Naso tang with brain injury?
Here is the deal. I look in my tank and notice my naso tang is nowhere to be found. I look and look then finally spot him in a corner under some rock fluttering against the rock and back wall UPSIDE DOWN! I immediately get him into my QT tank. I notice he has a large gash/chunk of his forehead missing! What on earth?! After I place him in my QT upright, he immediately flips himself over and starts swimming upside down! He refuses to flip himself back over... My questions:
2) How could he have been injured like this? Banging head on rock? Attacked?
3) is he a goner?
4) what should I do to help him?
