Hello it’s my first time keeping apistos and WC fish. I am thinking of buying a trio of atahualpas because their gender cannot be identified yet due to them not being adults. My LFS is very specialized in wild caught fish and very helpful so they gave me a lot of information about this amazing fish. My question is: is it better to keep them in 12 gallon species only (if I get 2m and 1f I plan on rehoming the one male to one of my other South America tanks) Or in a 40 gal with 13 cardinal tetras and a breeding pair of albino bristlenose plecos? Thank you in advance. Any interesting tip from anyone who owns this fish would be greatly appreciated.
