I need help with my mandarin

[mistergerardob]

My tank is a 80 gallon, I have between 90 to 100 pounds of live rock. I have the following fish:
a ocellaris clown fish.
yellow tang.
Fairy wrasse.
Wheeler's watchman goby.
royal gramma.
And yesterday I got a mandarin, which I think is my final fish. My tank have 9 months. My problem is that the clown fish is attacking the mandarin, he bited his tale, and then something got in the clown fish mounth, something sticky.
what can I do? Should I try to catch the clown fish? Do you think is something that past with time?

I had a Tomatoe Clown that got mean with age. Now he lives in my Trigger tank. Some fish seem to get aggressive when they get a little bigger or older. Many get a favorite space and defend it. You may have to give it away ,or try to trade at the LFS.

I'm very surprise that a ocellaris clownfish can be agressive, mine is a tank bred.
I will be very sad if I had to choose between the mandarin and the clownfish. I was thinking that my biggest problem will be feeding the mandarin, no my clownfish.

She may have just showed the new guy who's tank it is.
I'd just keep an eye on them to see if it continues.
I'd be more concerned w/ that fairy wrasse for pod competition.
Hope you have a fuge.

If I move the clown fish out of the main tank, How long will it take for the clown fish to be able to return?
I just saw another attack.

If it's just bumping I wouldn't stress.
If it's tearing fins, I'd pull the clown, rearrange tank to fool clown into thinking it's the new guy.
