I started out with a trio. But as Diana said, very finicky eaters. Two lasted about two months. The other lasted over a year. Never really fattened up like most fish. Also, it lost most of its color. Ended up very pale. I now have some Hawaiian bicolor anthias that are doing very well at 4 months. They have maintained their bright colors on a diet of frozen Formula I, mysis, clams, and pretty much whatever else I put in the tank. Good luck if you decide to try the evansi.
