I dought it, but feed him on meaty foods like bloodworm and prawns. I always recomend feeding prawns to more carnivous fish. Just thaw them out and hand feed him. This will stop the other fish getting a share. Do you know its scientific name? There are a few species called Bumble Bee cats, and some may prefer different foods to others.
Hope this helps, Max
When i kept a microglanis, he ate whenever I wasn't looking. I fed with a variety of foods, and I kept him for some time, but I couldn't tell you what he ate.
