A girl at school brought in two bettas as part of a ecosystem project she is doing. The fish were doing fine, water was changed regularly and they were fed. But some very mean and selfish person put the two males together! One came out fine, but the other is bleeding on his face, has torn fins, and breathing very heavily. Is there anything we can do to help him? Will a vet be able to do anything? Or is it a wait and see thing?
