Tannable i have the answer, my Oscar, BGK & JD !!!
Michael, I doubt they will fetch anything. firstly being a hybrid and secondly being a potentially highly agressive fish. Convicts are very very common.
if they had hundreds of babies (which is likely) then you would be better of trying to catch and seeing if anyone will buy feeders off you although they would need to be of some size to be worthwhile even for that purpose.
i personally would just leave them to be eaten by whatever tank mates you have.
