my females attacked 2 of my (1 in)males.(they live in a 10 gallon tank, with 5 more small(1 inch) females and one 1.5 inch female. i tried to give them away, but nobody wants them. they're acting like they're fine now, except they have really bad fin damage(one of their gonopodium's been gnawed off). i don't have the heart to euthanize, but when i try to give them away nobody wants them, and i don't have the money to buy them another tank....what should i do?
