Well, that depends on what else you have in the tank. I can tell you from experience, almost monthly, lol, that quarter size angelfish will chase baby BNs down and eat them. So will my convict cichlids. And my rope fish loves them. My guppys and plattys pick at their tails and fins. The biggest problem with baby BNs is that they think they are much bigger than they are, and will refuse to hide. I would not put them in a community tank until they are at least an inch long if at all possible. It has gotten to the point where i will take the male and put him in a little tank and let him kick out the babies, then put him back in the big tank. That is, the ones I want to raise, all the others, they are on their own, some actually end up surviving, and grow up.
