Hey! I am new here, and I am having trouble identifying if my angelfish has fin rot .So this is my year old male angelfish. I’ve noticed his fin looks like it could be fin rot. I have had it in my tank before (more than 9 months ago),but this time I am unsure.
There was a fight with the other big male in my tank just now, so it could be from it, I have not noticed this during feeding.
