Cryptoheros nanoluteus is exactly what I am looking for, granted they similar to HRP's and Cons - yet they are very different. although, some places say they're difficult to keep? any input? I found a picture of a river in panama, which inspired me, so I think a panamese biotope is on the cards. now, to locate the nano's
Nano's are rarely available. Last time I saw them was on wetspots list on aquabid. There were panamensis and myrnae available on aquabid last time I looked.
