Clownfish Tail Rot

[Patow]

Hey folks,

Went away for the weekend with my tank in tact. I noticed before I left that one of my clownfish had slight damage to its tail fin. I thought nothing of it, and assumed he just damaged it. Came home to find that the tail has completely rotted away. There is barely anything left of it.

I'm wondering if it is worth trying to treat this fish (I'm guessing the fin will not grow back?), or whether I need to bite the bullet and put this guy to rest?

Any advice?

Cheers,

Dave

Is he alone in the tank?

No, there are a few other fish (one other clown, watchman goby, and a mandarin). None of them are showing any symptoms....
