Thought my pbt was a goner... Took a + turn

[Viggen]

A few days ago I think my pbt and Sohal got into a spat..... He had a pretty severe .75-1in gash on his side that lasted for probably 6 days.  The first day or so I was worried but he continued to eat and was fine. Mother 2 or so days ago the pbt who is normally probably close to .5 in thick balooned up to 1-1.5 in thick.  Very funky growth bubble in the center of his body..... He kinda just wallowing around looking like he wasn't going to make it..... But somehow he still ate

Today I get home from work and 100% of the swelling is gone and he seems mostly back to himself......

Last night my mata tang had a inch plus long gash on his side..... It was very deep with blood color in part of it...... He seems ok today

Thinking of putting a mirror in the tank to hopefully dilute the attitude......

My yellow eye kole tang also seems to have quite the attitude..... But I think the Sohal is who picked on the pbt and mata

Can you add a referee fish to help control things in the tank.  Sounds like some time out would help:)  At least the 2 tangs are healing.
