You cant change their nature. You'll need to get rid of him.

Panthers are considered "peaceful"

you could get the panther out for a couple of days then try re introducing him to the tank... that way the panther is now the newcomer to the tank and hopefully it'll stop attacking....

If that still fails then take him back

What about rearranging all the rock

Saltwater Aquarium Fish for Marine Aquariums: Panther Grouper

Groupers are not peaceful. They are very aggressive. Esp. The panther grouper.

Btw they need a 300 gallon tank.

Not keeping it in a 90... It's a baby

Thats a story for another day. The point is that these are aggressive fish and you cant change nature. They will harass your other fish.

Lets back up for a sec. I've seen hundreds of panthers kept with other fish. Even one at my lfs has one with a flame angel that's 1/5th it's size. I've also kept one with a clown fish while be was young. He cannot fit any of these fish in its mouth. Does anyone have any suggestions that would help besides the ones alrdy given

Idlook for tank mates that could stand up to the grouper. Honestly, removing the grouper and letting the new fish settle in is what I would advise. How big is he?

I believe that its because you've introduced other fish to the panther's home and it doesn't really like that. as I said before I believe if you can rip the panther out and setup a mini aquarium for a couple of days with him in there then pop him back into your DP again..... that way the panther would now be the new fish which may stop the fighting.

Ive done this with a yellow tang before. introduced a vampire tang and the yellow practically destroyed it. I ripped the yellow out of the dp and left him alone for a few days in a mini tank... put him back in and no more fighting

Groupers at most 3 inches. The fox face is prob around 4

Panthers are considered "peaceful"

Where have you seen Panther Groupers classified as Peaceful? Groupers are aggressive and territorial. The best bet if you are going to keep it is the idea given to take it out, rearrange the rock, let the others establish their territory for a day or two and reintroduce it. I still think it will end up choosing a new spot and will likely cause the same issues.

As I am sure you know with all of your experience with them, they grow fast and add a tremendous amount to your bioload.

Good luck and keep us updated.
