i have heard convicts are supposed to be quite hardy fish, but i would like to know the best spawning conditions. since i have bought mine they rarely come out from under their separate caves and when they do it is only to move to a different one. i had to take out my filter and pump for about 30 min. and by the time i came back both fish were more active than i have ever seen before. do they need calmer water or might that have been what they needed to loosen up? i'd like these thing to breed as soon as possible?
