I just moved a pair, or so I think, of convicts into my 55 from my 240 gal to spawn. The female has already had one previous spawn but it was with my third con. Now the odd male out from the first spawn has a large bump on his head. The one and only female he is with now has a red belly again. Do those two factors always mean its a spawning pair? Was I right to move them. Is there anything else I should know to raise a successful spawn?
