One of my cory cats has fin-rot and it is just not getting better!
It started about 3 months ago, her dorsal and tail fin got torn during a spawing chase. She started to heal up, but then I noticed the beginings of fin-rot and began treating with Melafix and Primfix. During the 7 days of treatment the fins heal, but as soon as she is released into the main tank her fins get bloody streaks and a opaque white edge again. With-in a couple days I'm right back were I started. For the past three days she has rapid gill movement, but not gasping or darting frequently to the surface. I'm now running an air stone to see if it helps.
I've had her for about 8 years, she is my oldest fish. I don't know how old she was when I got her, but she has alway been big (for a cory), about 3 inches from tip to tail.
Currently she is in a planted 35 gallon tank with 2 other (younger)cories, a single discus, some ottos and shrimp. One 50% with gravel vac and two 25% water changes are done weekly; Ammonia 0, Nitrites 0 and Nitrates are less than 10, so I don't think it's a matter of water quality.
She used to "cuddle" and play with the other female and male cory, but they have been ignoring her. Now she just sits alone under a plant or diftwood.
Could the high temp of the tank (82 for my discus) be causeing the rot to come back?
Why isn't she healing up?
