have a 6" geophagus, a 6" jack dempsey, a 4" jewel, a 4" cigar fish, a 4" clown loach and 8 neon tetras...they are in a 72 gal-end quote
Well. Frankly, I'm surprised that you have any Neon Tetras at this point. I doubt you'll have them much longer. I don't know what a "cigar fish" is. I'd be concerned about the Clown loach and the potential for it to end up missing it's eyes and swimming around the tank soon to die... JD being the culprit I'd guess. the Geophagus and Dempsey and probably the jewel can go together in there. The rest of them... DOOMED!!!
