Behaviour and Tankmates
Spends much of its time resting on the bottom, and darts short distances, often claiming a small territory.
Can usually be kept in a small group if each fish has its own shelter.
Males often defend a small home range.
Best with small, peaceful fish, or in a species tank, because it may struggle to compete for food. It may eat baby shrimp. Choose its tankmates with care.
Water Parameters
Keep the pH steady, because this fish is sensitive to swings. This fish prefers cooler water than most tropical fish, and it may not need a heater in a warm room.
Parameter caveat
Add this fish only to a mature, fully cycled tank, and keep up regular water changes.
