I am bursting out of my seams with no market for them... I think everybody in town has at least 30 of my guppies, I've given to every kid on the block, every classroom at school has a tank of my guppies.... and I think at least 200 new ones are born daily.... My swords, Mollies and Convicts are all going the same way... I just cannot stop them from breeding.... Is there some sort of birth control that I can add to the water??... What can I do???
