Yellow tang was munched on?

[Laddair]

Hello everyone, so I come home from work to day and as I am feeding I notice that my tang is missing some skin.
I don't think no one is biting the tang or chasing during the day. I only have 2 other fish and they are clowns. One almost 4 inches could she be the culprit?
Please help out if you know what could have happened or any tips so it does not get infected.

I wouldn’t worry about it, it will grow back!

I'm not talking about the fins. They got messed up in the house move a month back. I talking about the white patch under the pectoral fin.

What type of fish food you feed, looks a lot bit skinny! It could be of lack of vitamin.

I have been feeding my tank with a mixture of pellet foods. PE Mysis pellets, Hikari Marine food Pellets, and Nori pellets mixed together. I keep it in a small jar with a silica packet to keep it dry.

I have been supplimenting with Two Little Fish Nori. every few days.

Last Sunday I have switch to Hikari Bio-Pure Frozen Mysis and Spirulnia Brine shimp cubes. I have noticed that all fish have started getting fatter.
