The Chrysichthys is in a CA-tank with big cichlids... so I dont worry for them, im more worried for the Chrysichthys because his skin looks a bit soft. But they seem to get along ok so far. The water is very hard and has a ph over 8. It should be perfekt I think.
I have been i contact with the previous owner, I he had fed him bolied ham

!!!
But now he is fed rozen bits of fish in the night, I think that must be better.
I have sent this photo to Prof. Sven Kullander (Senior Curator of Ichthyology, Swedish Museum of Natural History ) , maybe they will add it to the Chrysichthys brachynema illustrations at FishBase.com:
