My 5 year old Yellow Tang experiencing Tail Fin Recession

[Cire]

I appreciate any help in advance.

My Yellow Tang (who has been with me for 5 years and counting) is experiencing tail fin recession. First I thought he got in a scuffle with my Maroon Clown, then I noticed that there are a couple of orange "dots" on the its tail. My "hospital tank" has turned into a frag tank over the years so tonight I will be setting up a proper hospital tank to take care of my buddy. Any advice on what this could be, treatment and/or recommendations on setting up the hospital tank would be appreciated. I plan to use some sponge material from an established tank for nitrifying bacteria. 20 gallon. HOB filter. Heater. PVC for hiding. Power head for a little flow. Please let me know if you have any advice. I love this little one and want to make sure I it the best. Thank you.

Those chunks missing are so defined I would assume bites on first glance too. What makes you think it isn't? This is the first time I've heard of orange dots on the fins signifying something specific.

I agree with Steve - that that is not 'tell recession' - instead - its tail 'injury' from 'something' in the tank - my guess is its the maroon clown. There is no indication that I can see of infection. hope this helps - was the maroon clown added later?

Dropping my 2 cents, sure looks like a couple of bites, very clean bites. Looks a lot like my Flame Angel's tail when he angers the purple tang. Grows back quick though.

Reminds me of the melanurus wrasse I had that really liked to follow my Indian black trigger way too close, like right under his tail. One day the trigger turned around and bit a chunk out of his tailfin. Melanurus figured it was better to keep his distance after that.

Maroon clowns are on my list of ‘never again’ fish!

Definite bite marks and will grow back, but the aggressor has to be separated
