Care

Tank: an estimated minimum of about 100 litres (our estimate from its 10 cm adult size), with plenty of rockwork and perches to sit on, and moderate flow. Water: 24–27 °C, pH 8.1–8.4, salinity SG 1.023–1.026. These are general marine aquarium figures for a tropical species, not species-specific values from the sources. Keep nitrate low and oxygen high. Behaviour: a small, camouflaged fish that sways to look like a drifting leaf. Safety: the fin spines are venomous. A sting is very painful, so keep hands out of its reach during tank work, use long tools, and get medical advice if stung. This entry was written from the list only; check details before relying on it. Sources: Wikipedia, List of marine aquarium fish species (en.wikipedia.org/wiki/Listofmarineaquariumfishspecies).

Diet

An ambush predator of small fish and crustaceans. Start with live or moving foods if needed, then wean onto frozen shrimp, mysis and chopped fish offered on a feeding stick, two or three times a week for adults.

Compatibility and tank mates

Listed as reef safe with caution: it ignores corals but will eat small shrimps and fish. Keep with peaceful fish too large to swallow, and avoid boisterous tankmates that outcompete it for food.
