Rev I used to breed cards and they are easy, but make sure once you get them paired of that you remove the others that are not paired or they will be beaten up and sometimes killed. It happened with mine unfortunately. The first few days the parents will not eat them but the longer you have the babies in the same tank some will get eaten by the once parents. You also have to be careful that the female doesn't want to breed so much that the male eventually starves. The breeding pair I had would reproduce almost monthly. They are one of the easiest but costliest fish to breed because of the low birth count if you were to start a full operation. That is why there have been very few major breeding operations with these fish. The most young I got out of my pair was 29 babies at anyone birthing, so when you think about it you can breed other fish that give 100's maybe 1000's of young the birth rate is very low with cards.....I am thinking of getting another pair to try again, also check out wetwebmedia.com they have some get info over there on breeding cards and other fish as well.....I lost my pair when a yellow tang went nuts and killed my male and 3 days later killed my female. Good luck Rev.
