I think Platinum and Ying have fin rot. Platinum has a white patch on his dorsal fin where it looks torn. He also has it on one of his other fins. Ying's tail looks torn up like he was digging or something and I'm not even sure he's still alive. If I can I'm going to Birds Galore to get medication. If there's anything I can do now, please tell me. Also, what meds would you suggest?
