Ive gotten a few tangs with hlle. One yellow tang from a tank that the guy literally just stopped doing anything to. The tank was nasty and the rocks literally looked like they had cobwebs on them.
He stopped feeding them so it was extremely skinny.
Got him home and got him eating. Eats lots of pellets, nori and frozen once in a while. Hes nice and fat now.
His scares healed but he no longer has the long flowing top and bottom fins, he has a few "horns" at the front that are healed up and some of his back fins left. His face is scared white.
But he eats like a pig and isnt shy at all!
Other one was a blue hippo and purple tang. Immaculate tank, fed daily, but had carbon in a reactor in the sump-which is what i think caused it
Hippo i gave away as i already had one. Purple tang got healed up, most its fins recovered but still has white scares around the eyes that will never heal.
Feed well and dont run any carbon is my opinion. Some people say its if the carbon tumbles, it gets in the tank and causes it. I just stay away from it
