Sorry, I am reposting this question bc no one commented on the last thread. Anyways, back to my question.

I recently bought two clownfish from the lps and I noticed one of them has a piece of it’s tail gone. I am wandering if anyone knows what may of caused this. Ich? finrot? another fish nipping?

Here’s a couple photos
