I have found very hard to count the fish in one of the tanks to determine if it could handle more babies. So what I have done is set up one tank with just the breeder fish (usually no more then eight) and as they have babies, move the offspring to the other tank. If that tank has reached its limit it will tell you and will not move any more fish to it. I’ll then use my sale tank to hold babies and move them out before I click on the sell button.
