I have quarantined this chalk bass for 3 weeks and treated it with Cupramine and Prazipro. It's been on the main tank for a week and today it shows signs of what I think is fin rot. Question: is this really fin rot? If so, is it ok if I use and antibiotic like Maracyn Two in the main tank (I have corals, snails and crabs)? Otherwise, what are my options?
