These fish are very difficult. From my experience here is what i know. Mine has been in my tank now for a couple years and its always a struggle. The little guy will disappear for weeks on end. they are nocturnal... meaning they hunt and only come out at night(at least mine). Luck for me i get up very very early in the mornings. This fish also feel much more comfortable where it can hide in rocks and scoot around the bottom. I have never seen it swim in open water. I fed mine live ghost shrimp at the end of a pair of tongs for a long time until it finally took to froze. maybe try some very small ghost shrimp. Give it somewhere to hide. Good luck!
