    Food and feeding: Crustaceans, worms, molluscs. A bold unfussy feeder which will accept most food offered right from day one.

    Additional notes: Best kept in a FOWLR (fish only with live rock) set up with other robust fish. Picasso triggers are inteligent fish and will soon learn to recognise when they are about to be fed, they will even take food from your fingers after just a few days, but beware. Even a 2" specimen is capable of removing a bite sized chunk from an unwary finger tip.
