Very neat little laid back fish, if you have a tank that can support it. I have two of them and neither of them will eat any prepared foods as previously posted. The do sift sand, but ever so minimally, and even in a nano sized tanbk its not a problem. Its too bad they are not that easy of a fish to keep as they would certainly be nice in a lot of tanks as the prices in this area are good....$12.50 or so each. Just like a mandarin, nice cool fish, cheap enough to have, hard to keep in most tanks.
