I have 11 pygocentrus nattereri (RBP) and what were the chances of them breeding ? There was a thread in the piranha section of the forum, which 2 paired together out of like 8-10 and decided to breed right in the end of the tank. Ofc they were extremely protective of them and fought out any that came close. You guys think that may be possible for my RBPs to do the same? Is there anything I can do to make the chances higher ? thanks in advance!
