Seahorse Tankmates: What’s Safe, What’s Not?

Pipefish can make very interesting and unique seahorse tankmates, although they pose some of the same problems as wild-caught seahorses.

Pipefish can make very interesting and unique seahorse tankmates, although they pose some of the same problems as wild-caught seahorses.

Let’s be honest, there are very few seahorse keepers who truly wish to keep their seahorses in a species-specific aquarium. Although there are some keepers who insist that no species of fish, coral, or invertebrate should ever be kept with seahorses under any circumstances, there are quite a lot of animals that will do exceptionally well with seahorses while still allowing the seahorses themselves to thrive. To guide seahorse keepers in stocking their seahorse tanks with non-seahorse inhabitants, I have compiled a list of species that are appropriate for keeping with seahorses. This list should be used as a guide only and not a definitive reference.

The species are categorized as either a 0, 1, 2, or 3. The 0’s are the most docile species around– they’re even safe with seahorse fry! The 1’s are completely safe all the time with small to large horses, almost no exceptions. The 2’s are, aside from the occasional rowdy specimen, safe. The 3’s are a bit of a gamble, but work in some cases; watch them with care and be prepared to relocate them if they become a threat to your seahorses. Species marked with an asterisk (*) are suitable tankmates for seahorses (based on their numbers– 0, 1, 2, or 3), but often fail to thrive in captivity for various reasons. These species are not generally recommended for any tank, but they should be referenced anyway. Anything not on the list may not be safe for seahorses ever, but they may just have been overlooked (or in some cases may be a newly-described species).

If you have any questions about unlisted species, feel free to e-mail the author or to visit our Tankmates discussion forum. By the way, the list so far only includes species safe for regular-sized, tropical horses. And please, please, please do not hesitate to ask about any one of the listed or unlisted species you may have a question about! Now on to the list…

    I think It would be good if I pick clown fish, star fish and shrimp (if i got a seahorse). Good information to keep us aware on species that safe for them. Thanks.

  2. bunniehightower Says:

    I have 3 horses and found this very interesting

  3. Michael Bendis Says:

    This was very good information, though I’m a bit more experimental and I think that survial of the fittest is best approach… I’m wanting to add a puffer fish with my seahorse, and I’m hoping they can survive any onslaught. If not … well than…damage!

    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    This is a very irresponsible way of thinking! if you can’t do whats right for the animals you keep then don’t keep them period!

  5. Will Wooten Says:

    I hope you realize this is like saying, “I’m a bit more experimental, and I think that survival of the fittest is the best approach. I’m wanting to keep a lion with my Golden Retriever puppies, and I’m hoping they can survive the onslaught! If not, well then, damage!”

  6. AMY Says:

    I HAVE BOUGHT 3 SEAHORSES I HAVE ONE CORAL BANDED SHRIMP AND I WANTED TO KNOW IF THE SEAHORSES ARE SAFE IN THE TANK WITH THE CORAL BANDED? THE TANK IS 55 GALLONS. THANKS

  7. Cindy Says:

    on a scale of 1-4, four being the least suitable tankmates for Seahorses
    a Coral banded shrimp is a 4. I would avoid them.
    Sexy Shrimp are really nice and they have a 0 threat level to Seahorses.

  8. amy Says:

    I HAVE TWO ADULT H. KUDA SEAHORSES ONE FEMALE AND ONE MALE. I RECENTLY PICKED UP TWO BABY SEAHORSES THEIR BLACK NOT DEF ON BREED BUT ITS SO CUTE THE ADULT SEAHORSES TOOK RIGHT TO THEM. AT FEEDING TIME THEY RIDE ON THE BACKS, TAILS AND SOMETIMES SNOUT OF THE KUDAS AND ITS SO NEAT TO WATCH. I ALSO HAVE A SCOOTER IN WITH THEM SINCE ONE WITH THE KUDAS GOING ON 8 MONTHS. I AM GOING TO ADD A CLEANER SHRIMP TO THE TANK. I HAVE GREAT PIX OF THE SEAHORSES I WOULD LOVE TO SEND AND SHARE WITH THE REST OF US SEAHORSE LOVERS PLEASE LET ME KNOW WHERE TO EMAIL THEM THANKS. AMY B. NEW JERSEY

  9. REEFMAN Says:

    AMY I RECOMEND A PIPE FISH INSTEAD OF A CLEANER SHRIMP, CAUSE THE PIPE FISH WOULD BE MORE BENIFICAL IN THAT IT DOES EAT PARISITS OFF FISH LIKE CLEANER SHRIMP DO. ALSO PIPE FISH GET ALONG GOOD WITH SEAHORSES, THE SCARLET SKUNK CLEANER SHRIMP IS ALSO A GREAT ADDITION CAUSE IT WILL CLEAN YOUR TANK OF MYSIS THAT THE SEAHORSES DONT EAT OFF THE BOTTOM AND WILL ALSO CLEAN YOUR SEAHORSES AND ANY OTHER TANKMATES. GOOD LUCK WITH THE LITTLE ONES.

  10. Cindy Says:

    Great advise reefman, however I would be very careful adding any pipe fish in with my ponies
    that are wild caught like the ones you normally find at the LFS instead buy them from a reputable tank raised facility otherwise you run the risk of introducing disease to your ponies.

  11. admin Says:

    Amy, good timing – I am working on adding a photo section to the site and it will be up very soon. If you want to send your photos to me, I will make sure they will be included. Sent them to aquagrrl “at” gmail “dot” com.

  12. Michialah Says:

    I would love to add starfish to my seahorse aquarium but everyone else is saying its not safe.
    HopeLessGirl22@yahoo.com

  13. admin Says:

    It depends on the species of starfish. Some are predatory and are not safe. Chocolate chip starfish are ones that are NOT safe but a lot of places carry them. Other starfish might be okay but are really sensitive to captive environments or need extremely large, well established tanks to thrive. I personally wouldn’t try it.

  14. Nicky Says:

    Great information. Would you add any crabs at all? I need a cleaning crew the is suitable with my seahorses (Reidi’s) and i really don’t know what to put in. I don’t want starfish. Any suggestions? I have a 30 gallon tank. Argonite substrate.

  15. Aquagrrl Says:

    There are varying opinions on crabs. I’ve had no problems with blue leg hermits. I’d use caution with anything larger than that. I’ve also kept sally lightfoot crabs with seahorses, but I made sure to watch closely. A lot of it seems to depend on the individual crab’s personality.

  16. Sue Says:

    How well different species do in the same tank? I recently lost my H Reidi female and wanted to add a female and a new pair of reidi. I found they’re now hard to find… could I add a pair of another tropical seahorse species?

  17. admin Says:

    There is quite a lot of debate over whether its safe to mix species. Some say that one type of species can be a carrier for a disease that others are susceptible to. There as never been a clear answer. If you’re keeping true captive bred seahorses, then I think its much less of a risk, though I would absolutely make sure that they’re from a reputable breeder, as local fish stores often don’t really understand the difference between tank raised and captive bred. And always quarantine! Even captive bred seahorses should be quarantined in a cycled hospital tank so you can monitor their feeding, behavior, etc . . .

  18. Chuck Says:

    Great information! I was put off at first when doing my seahorse tank with two H. Kuda as I wanted a diverse and colorful tank. They have been living happily for nearly a year with several tank mates. My stock includes, scooter blenny, skunk cleaner shrimp, a variety of corals zoas, polyps, Florida Ric, common mushrooms, Kenya Tree, Corky Finger Gorg, and pulsing zenia. The only issue I had was a Diamond Goby that just got a little too greedy at meal times.

  19. Cindy Says:

    I have lots of live rock,live coral,seahorses,pipefish,firefish,jawfish,and a watchman with asst snails and they all get along great.

  20. Cindy Says:

    too bad you cant see the pics.

  21. Nicky Says:

    What size of a tank will also allow you to have many different things in you tank!!

  22. Nicky Says:

    One thing that I always wondered is with these true captive bred seahorses is how many are bred with thier own family (for a better word)? Doesn’t that have any affect on them say like dogs? What happens when they interbred??

  23. Cindy Says:

    I’m using a RSM 250 66 gallon because I like lots of room for all kinds of pony safe coral and other suitable tank mates “fish”. I really don’t think you need to worry about them being inbred lol they are not dogs. I purchased my seahorses and pipefish captive bred and it’s one on the best decisions I made, they do cost more but it’s well worth it and I figure if you can’t afford captive bred then find a different/cheaper hobby.

  24. Robert Says:

    Well being that i am just getting started. I have fresh water tanks for years. But the Wife have been after me to get a salt water tank set up and get here some sea horses. I got a 75 gal and a 55 gal store away. Its seam to be a large tank just for sea horses if i cannot add much else. But by what i have read they are enough by them self. So dos any one know if LED lighting is good for them? Brit white and deep blue at night? And i take it i cannot have sand not sure what to use or if i need lots of plants? Looking foward to it.

  25. Kevin Says:

    Are dwarf seahorses compatible with acan and chalice corals?

  26. Cindy Says:

    you can have lots of corals and fish with Seahorses most reefers like me do not want a species only tank but I would avoid LPS because most pack a sting. vertical is most important when choosing a suitable tank for seahorses unless you are going for dwarf/pixies. blue Linkia starfish work well in a seahorse tank because optimum temp for my ponies”Erectus” is 75 degrees the blue Linkia also do better in a cooler environment provided you have a big enough tank and live rock for the star to feed on.I use a chiller to keep the temp @75. Seahorses also do well in lower lighting I would imagine LED’s would be a bit too bright I use 6xT5 one white three blue plus and two actinics, I do supplement with LED’s on my 180 G reef along with 4 T5 and 3 HID’s but I don’t think I would use LED’s on a pony tank. I have sand in my pony tank I prefer the look much better then a bare bottom tank I vaccuum the sand bed with every other water change and keep lots of narcissus that help to keep the sandbed clean but I also feed my ponies with a turkey baster and let the enhanced mysis dance on the end of the baster and they grab it which keeps the mess at a minimum while feeding them, I make sure each pony gets 3-5 mysis @ each feeding twice daily they are pigs so I’m careful not to over feed.

  27. Evangelo Says:

    I got 6 chromis in my tank since on here it said they are a danger of 1 but i went on the seahorsesource and they said danger 3…:s what problem can they cause??? :s are the simple clownfish better?? aaaaa i dont know what to do now as i am buying my seahorses in 2 weeks!!! any ideas anyone? chriyonce@hotmail.com
    thanx!

  28. Kim Stanion Says:

    I just got a 7 gallon jellyfish tank. The manufacturer says I’ll be able to keep 3 Moon Jellies happily in this tank. It also says the Moon Jellies do not sting. I’m wondering if I could get 1 Jelly and a couple pipefish? Thanks

  29. admin Says:

    Unfortunately, jellyfish should not be kept with other fish at all. Fish can easily damage the delicate tissue of jellies. Additionally, it’s not exactly true that moon jellies have no sting, it’s that it’s mild enough that most people don’t typically notice it (be warned though, that if you have sensitive skin you too might feel it). A small fish like a pipefish feel it would, and would have no way of avoiding it. I would just stick to the jellyfish.

  30. aira Says:

    thanks for this useful information! i think i still need to educate myself before i could get seahorses to take care of. i have always loved to do this for very long now but i realized that it takes a lot of time to actually do this.

  31. Mamasreef Says:

    So I have a blue eyed royal dottyback in my 8 g rimless. My plan is to ad a few dwarf seahorses. Dottyback pretty much keeps to her rocks. Do you think think they will be ok together? Also another question would kuda seahorses be to big for this tank? I’m not sure that’s y I went for the adorable lil dwarfs. Thank u :)

  32. Aquagrrl Says:

    Your Dottyback will likely kill any dwarf seahorses. As for kuda, they need a much bigger aquarium, minimum of 29 gallons. Some stores have been getting in very young H. kuda, about 2 inches in size, but don’t let that fool you – they will get bigger. Those seahorses are also not a good choice – they’re being sold too young and tend to not be very stable at that age, so a lot of aquarists suffer losses.

  33. Mamasreef Says:

    Ok well ill wait till my husband 75g is set up to get the dwarfs that way I can move her first. Is there any other seahorse that would be small enough for this tank? I want to be able to get at least a pair. So far I have come up with dwarfs as my best option for having seahorses :) thank you so much for your help :)

  34. Tami Says:

    Yeah, they really are the best option. There are some other species that could be kept in it such as H. fisheri or H. tuberculatus, but neither are really found in the hobby.

  35. Luna Says:

    I have 2 seahorses, 5 blue legged crabs, 4 nassarius snails, 4 turbo snails, 1 cardinal, 4 peppermint shrimp, 1 pipefish, 1 spotted mandarin and a banded serpent starfish…everyone gets along great! i have a good amount of liverock, super fine substrate (live sand) and a non photosynthetic gorgonian. i add in phytoplankton for the gorgonian and “reef bugs” every so often to help everyone out and keep my copepod population up for everyone too. love all my little guys and 2 of my peppermint shrimp are pregnant and will let those just hatch and do their thing…im sure itll be an edible treat for everyone and hopefully a cpl of the babies will survive and grow up too!

  36. Cynthia Says:

    Luna: What size is your tank? Thank you! What species are your seahorses? Thank you for any additional information.

  37. Cynthia Says:

    Luna,
    How long have your Seahorses been sharing a tank with the fish you listed above? Again, thank you for any info!

  38. anatolianlady Says:

    What about the dragon goby?

  39. Tami Says:

    Dragon gobies, a.k.a Banded Sleeper Gobies (Amblygobius phalaena) are generally peaceful except towards conspecifics. However, they do eat all the good microfauna out of your sand bed. Also watch, they can become greedy. I think it’s fair to say they’re mostly safe, but watch closely.

  40. anatolianlady Says:
  41. Andrew Says:

    Are pipefish safe with dwarf seahorses and how big of a tank do they require?

  42. Andrew Says:

    Are pipefish safe with dwarf seahorses and how big of a tank do they require? Also do all of these tank mates apply to dwarfs as well as bigger seahorses?

  43. admin Says:

    It depends on the type of pipefish. Florida pugnose pipefish are generally a good choice for wild caught dwarf seahorses. If captive bred, you don’t want to mix with wild caught pipefish with captive bred seahorses.

    As for if the same list applies for dwarf seahorses and larger ones, it doesn’t. Dwarf seahorses really do best only with the 0’s on the list, and maybe some of the 1s due to their diminutive size.

  44. Marg Says:

    Does anyone keep lephastrea or lithophyllon with seahorses?
    Please let me know if you do, or if i shouldn’t.
    thanks!

  45. Tami Says:

    I’ve not kept either coral, but a look at their biology, they’re probably only a small risk, but a risk none-the-less. I would think lephastrea would be the safer of the two, but I personally wouldn’t be comfortable trying either in my tank. If you decide to give them a try, watch closely for areas of discoloration on the seahorse, with these corals especially on the tail where they would be most likely to drag over one. And please report back your findings.

  46. Sharyn Says:

    great information on what to,,,,, not put in with horses……… i also asked down at local marine aquarium, they said if i was to put ,, any corals in at all,, which i still am not sure, they say to just start off with soft corals, which they label, for real beginners,,,,,,,,,,,,,,,, whats your thoughts on this

  47. Aquagrrl Says:

    Soft corals are fine with seahorses, as long as you have the light to keep the corals healthy.

  48. Joann Says:

    I haven’t gotten any sea horses yet, but would love to. My question is my son saw these neat Blue Dragon Slugs and was wondering if they were compatible with sea horses. I was reading about the Dragon Slugs on line and it says in the wild they feed on Jelly Fish so I was concerned if they would attack sea horses. If so then I would just have to get 2 separate tanks.

  49. Tami Says:

    Most slugs you see (nudibranchs, to be more accurate) have poor survival in captivity because they have such specific dietary requirements. It isn’t that the slugs eat jelly fish, it’s that is all they’ll eat. There isn’t really a good way to supply jellyfish to keep it alive. It wouldn’t bother seahorses, but it would likely perish.

    Lettuce nudibranchs are one of the exceptions. They are still difficult to feed, but can live on certain algae types. They are also pretty neat in their own regard (Google Image Search)

    It still takes some dedication to keep them, you have to have the right algae, they are partially photosynthetic so need bright enough light, and they are easily sucked into powerheads so protecting any intakes needs to be taken to the extreme. That being said, if you can meet their needs, they are really cool, and even have a blue variant.

  50. Alexis Says:

    Can dwarf seahorses live in the same tank as a non stinging moon jellyfish?

  51. admin Says:

    No. Moon Jellies do still sting, it’s just much milder than other jellyfish. Having been stung in the face, I can say more sensitive areas are not immune to their sting. Seahorses have very sensitive skin.

    Additionally, while I do not know much about jellyfish, I know they need an environment with as little obstruction as possible. Any hitching posts for the seahorses would likely be dangerous to the jellyfish.

  52. Michelle Says:

    I have seen many many many purple firefish in with seahorses at the monterey bay aquarium in California. I’m always confused when said they over compete with seahorses and or are aggressive to each other they both interacted with each other and left each other alone and completely ignored seahorses waiting for food to pass by like some seahorses (and my own firefish). some of the tanks in the “secret life of seahorses” display weren’t that big so its not a space principle.

  53. Michelle Says:

    I was wondering should prepackaged “live” sand be treated?

  54. admin Says:

    Most live sand has directions on the bag, I’d start there. It’s an obvious suggestion; but different companies may have different directions. Most don’t require rinsing, just adding directly to the tank because they’re kept damp to keep the bacteria alive.

  55. admin Says:

    Michelle, they’re listed as a low threat in this thread for the reason you indicated. They really don’t bother seahorses at all, and while they can be fast at eating, they fill rather quickly. As long as you’re feeding adequately, the food will get to a seahorse just fine. It’s just important with any fish to observe closely and make sure there isn’t any problems.

    With that being said, I had some firefish with a pair of H. comes and they were very shy, and did not mate until the firefish were removed. I think the bolting behavior of the firefish bothered them. Firefish are easily startled, and H. comes is a fairly timid seahorse, so I think the combination was bad. It’s just an example that every situation is different.

  56. Nathan Says:

    Ive been wanting to setup a nano reef specific with dwarf seahorses, I have a 24G JBJ nano cube that im already cycling. Whats the opinion of having nano whip coral in with them? is a 24G too big for dwarves or the LED fixture too much light? Also what are accpetable water params for them from top to bottom, and my biggest concern is feeding them, and keeping stock of their food source? Ive only seen brine shrimp as a source, are there others, and how would you keep them stocked enough to always have a supply of them? Im definently interested in doing things the right way before I buy horses, but also looking at cost effective ways being a single parent, my son just really loves all things saltwater!

  57. admin Says:

    Hi Nathan, have you seen the article on here Dwarf Seahorses As Pets? It answers some of these questions. As for brine shrimp, you must hatch baby brine shrimp, getting eggs from places like Brine Shrimp Direct. You also want to enrich the brine shrimp. I’d take a moment to join the forums so we can go into detail about your setup and questions.

  58. Elaine Says:

    As always such a reassuring reference site. Don’t know what i’d do with out it!!!

  59. Tera Says:

    What about Lion Fish?

  60. TamiW Says:

    Lionfish eat seahorses, so would not be a good choices for obvious reasons.

    Can u put tuxedo sea urchin in with sea horses thank u
