Seahorse Frequently Asked Questions / Are there any freshwater seahorses?

No. All seahorses are marine fish, though some tolerate brackish conditions (brackish being part way between freshwater and as salty as the ocean). Sometimes you may see a “freshwater seahorse” for sale in a fish store. These are actually pipefish, a close relative to seahorses. They don’t have the traditional horse-like body shape. They look like a stretched out fish, or even a tiny snake.
