Buffy has a lot of weird lumps/dark patches all over her body. She is by herself in a quarantine tank and was treated with AQ salt for 10 days. I thought it might be columnaris, so I adjusted her heater to 74 degrees, but she's already been like this for over 2 weeks.
There are no other symptoms, just a lot of dark patches over her body. The patches are raised and some of her scales are popping up. However, she is still active and has no other obvious symptoms.
Could this be a tumor? I was originally going to put her in a sorority, but now I'm scared to. Any suggestions would be great.
