Thanks, King-eL. 118, I didn't see that you had edited your post. You don't think a 75 gallon is adequate for those fish? Do you think it would be enough for just a pair of P. delhezi? I already have the tank. If it's not big enough for two P. delhezi I'll just stock it with some other kind of fish.
Also, does anyone know if P. delhezi can hybridize with P. teugelsi? I don't want to breed them together, I want to make sure it won't happen accidentally if they are in the same tank.
