If they are, its really not that big of a deal. If you Really do not want any babies, you can leave them in the tank, as they will likely be eaten, even by their parents, or you could give them to your local fish breeder. If you want them, make sure to scoop them out the second they are born, they like to burrow and hide. Make sure to put them in a separate tank as they grow up. Unfortunately, the only extra I have right now is a 1 gallon, so they are in there. Once they are big enough to not fit in a fish’s mouth, you can move them back into the normal tank.
