Anybody have experience keeping Centromochlus perugiae (oil/honeycomb catfish) with apistos? They remain small (5-6 cm) and are apparently surface feeders, which bodes well for apisto fry. SeriouslyFish suggests that they are "safe with all but the smallest of fry." Do you think a single specimen in a 40 gal tank (36x18x16") would be alright? I'm only looking to casually breed A. cacatuoides, so as long as I don't lose too many fry, I may give it a shot. Thoughts?
