Yesterday, I brought home 2 maroon clowns, one yellow one white stripe. They had been together for the last 6 months. I watched them closely, and they got along beautifully. I put them in my tank, and they were side by side all night. This morning, the white stripe was chasing the other clown and taking bites out of its fins. Then it would get close and back up right in the yellow stripes face. I don't have another tank, I know shame on me. What should I do next?
