I am treating my yellow tang for hexamita, the hexamita was brought on as a secondary infection of lateral line. He got the lateral line because of a lack of vitamins, after I started feeding him more vitamins the lateral line got a little better and stoped spreding, the lateral line has either gotten better or not moved for a couple weeks now. i am finishing off the hexamita, but i noticed that his upper lip is gone, he is alomost full grown so the thought that his teeth might show has he got older, but I can see his whole gum line as well. I am assuming that the lateral line made a come back and took his lip because he is all alone so no one else is to blame. What im asking is, does anyone know for sure why this happend? and can i help him grow it back, or is it gone for ever? i fear this my affect his eating
