I bought a swallowtail recently and she developed ich, luckily I quarantined her. I started treating with Kordon ich attack and a uv sterilizer because it worked on our blue tang. I don't think it's working in this case though, her fins have started deteriorating. I did a 20% water change to bring down my nitrates which were at 30 PPM's. What do you think is the best route for me to take now? Should I use Cupramine to treat for ich? What should I do for the fin rot? I'll start reading the stickies to try and help me but if someone had a direct answer for immediate help I'd greatly appreciate it! TiA!
