I have 3 female cpos in a 10 gallon. I really wanted 2 females, one male but was having a hard time finding a male in the batch. One of the females was berried with all black eggs when I bought her so I figured I'd just wait for the babies and eventually get a male. I don't know how long she was holding before I brought her home. Within a couple of days most of the eggs changed color. There are still a few that are black but most kind of match her body color now. I don't see any eye spots. She is still fanning them frequently and has picked a seashell in the tank to stay under. She stays in the shell all day and chases the other crays away if they try to walk past. Are these eggs fertilized?
