Overview
The red belly pipefish is a peaceful pipefish that needs a mature, gentle tank. Its slow feeding on tiny moving prey makes it a fish for experienced keepers.
Did you know
Slice a red belly pipefish across and its body is a seven-sided ring rather than a round tube. That shape gives the species its name, heptagonus, which means seven-angled.
Caring for the red belly pipefish
Give red belly pipefish a mature, planted tank of at least 21 gal (80 L) with soft flow. Add root and wood cover and dense marginal growth, since they hang low among the plants in calm water.
The red belly pipefish adapts to fresh or lightly brackish water. Keep it warm at 75 to 84°F (24 to 29°C), with a neutral to alkaline pH of 7.0 to 8.2. Stable water and a steady supply of tiny prey matter more than exact salinity.
It feeds only on small moving prey. Offer newly hatched brine shrimp, copepods, Mysis and small mosquito larvae several times a day.
It is peaceful and social, and you can keep it alone or in a small group. It is a slow, deliberate eater, so choose tank mates with great care or leave them out.
The female places her eggs onto the male, who carries them and later releases live young. Males can begin brooding at only six to eight centimeters. The species is not known to breed readily in aquaria, and breeding is hard.
Good to know
The red belly pipefish, Hippichthys heptagonus, is also known simply as the belly pipefish. It belongs to the family Syngnathidae.
In the wild
