I am tanking advice. That is why I am here. I love my fish and would not hurt them. I am going to let mama fish eat her fry, that is all I can do. I did not know getting female fish would cause this kind of problem. If I did I would not have bought them.You have very small odds of rehoming fish for free let alone trying to sell them even for the $4 they sell them for at petsmart. It took me months to find mine a home. I will never put myself through that again. You won’t take the advice you haven’t yet. Your tanks are overcrowded and it’s a pure lack of respect for the animals. Play god now to avoid a several month or longer headache of musical tanks and new set ups, or most likely in your case since you said you can’t add another, dead fish.
