Freshwater Pipefish Tank Setup
Give them at least 120 litres (32 US gallons) with gentle flow, plenty of things to hitch onto, and no rowdy feeders to outcompete them. Keep the water at 75-82°F with a pH around 6.5-7.5. They reach about 15 cm as adults, so don't be misled by the small juveniles sold in stores.
What Do Freshwater Pipefish Eat?
They're not fussy eaters - feed a varied diet, rotating good-quality dry, frozen, and gel foods rather than the same thing every day, and match the food size to their mouths.
Freshwater Pipefish Tank Mates
The Freshwater Pipefish is peaceful, which is the first thing to weigh up when you choose tank mates. Good matches come down to the whole stocking list working together - temperature, tank size, and temperament - not any single label. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are Freshwater Pipefish Good for Beginners?
Care demand varies by line and setup. Match the care level to how often you actually test and change water.
