Having an issue with my clownfish

[ReeferNick13]

Noticed that my clown fish tail looked like this today. It looks like it’s split. Anyone know what may have caused this? Parasite? All of my parameters are in check. Any helpful info would be much appreciated. Thank you

Maybe a little bite from another fish? Eitherway, it should heal. I wouldn't worry. Do you have a second clown?

It looks like another fish nipped at its tail. If you tell us what else is in the tank, we may be able to give more helpful advice.

I have a banggai cardinal fish and I just added a small royal gramma today but he has been hiding since I put him in the tank so I don’t think it was the royal gramma. Maybe the cardinal fish?
