I have a 20 gallon breeding tank for some apistos. And my 75 Gallon (the bichirs home) is going to be converted from an african tank to a south american tank (with some tweaks red-tail shark, and bichirs) But i need some Tank mated that will not nip at them. I have an ornate 5-6 inches, 4-4.5 inch palmas buettikoferi, and a senegalas 5-6 inches. As well as as 3 parrot cichlids and a pleco, (and going to add 4-6 apisto) I was thinking about some more apistos like 4 more or something like that, as well as 3-4 fire mouths, I haven't seriously considered it but angles. And i was going to let you guys suggest the rest. Anything will help. Thanks in Advance Dr.B
