About a year ago i purchased one of these and he unfortunately never ate. They seem to have dropped in price recently so i thought i'd give it another round. The geometric pygmy hawk is a very cool little fish. This guy is about 1 inch long and hides throught the rockwork all day. They would really be lost in a large tank, but in my 12 gallon nano you really get to see alot of him. The only thing he will eat is mysid or brine shrimp. They also have a very cool eye color pattern. I'll try to get a better shot but its a little tough since he hangs around the rock work.
