Here he is being still for a change which means the shredding can't be seen but the front of the dorsal fin looks suspect to me.
Here's the red spots on the caudual fins I was talking about. Also the front of the dorsal fin looks uneven and white, and I think that's shredding on the anal fins.
A different view of the caudual fins.
What I think is shredding on the pelvic fins.
As my posts no doubt suggest - I am a complete newbie trying to do my best by this fish and knew nothing about fish care or upkeep before he was given to me. I've tried researching fin rot and looking at images and it seems to match what I'm seeing above but I'd appreciate more learned opinions.
Please correct me wherever I am wrong in what I post and/or assume - I'm still learning.
