When they get out of quarentine my Nannos will be the only cichlid (and only non-Asian fish) in my Asian loach tank, but I hope to replace them with Pearl Chromides at some point. If/when I do that, I like the Nannos so much I am interested in setting up a small tank for a group of them. Other than livebearers, are there any good fish that could go in the Panamanian biotope with Cryptoheros Nannoluteus? Obviously they would have to be very peaceful toward them, since the Nannos are easily intimidated. I think most of the other Crypto species, or other bigger cichlids would be too aggressive, but maybe a group of Nannos could be kept with a single specimen of some other cichlid species that wouldn't seem them as competition and would leave them alone. Anything that would work? Any other non-cichlid fish that would go well in a Panama biotope?
