One of the mollies in my overstocked tank has been biting the other fish. Especially my swordtails. One is missing a ton of scales from the top of her head as a result. At first, I thought the swordtail was sick or had hole in the head. But discovered it was a result of the bully Molly. I watched it happen. Look at the poor thing. Her behavior has caused other fish to start biting too. So I removed her from the tank and put her in a 5 gallon carrying case. She looks so sad but I can’t put her back in the 60 gallon where she will continue to terrorize the other fish. My lfs won’t take her. I don’t know anyone else to take her. I do have another tank with a red tail black shark. My bully Molly is small. Probably only 4 months old. She also looks pregnant. I’m afraid that she will be killed or hurt by the shark. I’ve never had other fish in with the shark, so I don’t know for sure. What do you think? If she tried to bite my shark... I don’t think it will end well for her. I’ve had my shark bite me, and she is strong, scary. and huge. She almost hurts me when she’s annoyed. I don’t know what other options I have. I can’t purchase another tank. I have a 3rd already with other mollies, and she will just end up biting them. I hated this fish when she was in my 60 gallon. I kept wishing she would die. Because the way she was biting the other fish was horrible and I felt so bad for the fish she was constantly attacking. No one deserves to go through that. But now that she’s all alone in this little cage, I can’t help but feel horrible for her. It’s breaking my heart. What would you do? Should I risk putting her in with the shark? Or is there a way I can get her to stop attacking other fish? She seemed to bite everyone. But focused on some of the larger fish primarily. Especially this one swordtail who was always minding her own business and didn’t deserve to be bit. And to make it worse, she never fought back. She just tried to swim away. So the fish would just keep biting her until I intervened. And this has been going on for weeks. You can see what has happened to her head. This bully wasn’t stopping. Any advice please?
