Oh, I saw him getting chased! He is not suffering from the injury any longer, I am just asking how far is too far on this type of injury. I am asking if the tail has been chewed beyond the point of no return on growing back.
Yes I understand I shoulda rescued him sooner. I only have one tank (for now) and i ended up using a "breeding trap" net. And this was right after he colored up and decided to press the issue for dominance with an awesome red shoulder who perished. I am just sick over that, but now I have a contingency plan.
75 gallon tank is for growing out, new 125 for show and spare 10 gallon with a catfish for hospital.
