I bought this little (4 inches) juvi 2 weeks ago and its fins were already like this, hasn't really shown signs of healing if any. Can anyone tell me if its fin rot and what's the best way to treat it? Thanks in advance.
i would try to cut (U shape) the portion that is missing but not all of them so that the new grow out fin will have an existing structure to grow along. I cut the tail of my RTG before and it grow out just fine so don't worry about it's healing matter. good luck.
