So I've noticed one of my mollies today now has it's eye hanging out. Another one of my mollies seems to have some sort of whitish patches kind of on it's skin. I'm thinking it's a bacterial infection and I'm wondering if it can be transferred to the other fish in my tank? If it can be well then I'll treat the whole tank but if I just have to treat the affected fish then I'll move them to my other, smaller tank. Thanks for the help.
