Cause of nipped fin?

[Roman'sReef]

i’ve had my Banggai Cardinals for two weeks now and I added a royal gramma last week. The royal grandma likes to hang out exactly where the cardinal used to be but now the Banggai Cardinals is at the back of the tank. I often find the royal gramma going up to the banggai and he seems a bit uneasy. He appears to have a nipped fin

The royal gramma or banggai has the nipped fin?

It's probably from the royal gramma, yes. What size is your tank? Does the royal gramma have a "lair" where he mainly hangs out? Do you have any suitable caves that he could use as a lair?

For the longest time the bangai hanged out on the right in the caves there but now hes all the way on the right at the back and the royal gramma is where the bangai used to be

I would look at adding some more marco rock to create some more caves/hiding spots for your fish. It sounds like they both want that spot - but the royal gramma really wants it more and is prepared to defend his territory (my guess is he's "claimed" that cave and defending it against the banggai).

Ok imma move the rock infront of the caves since that all i can do for now…
Two questions in the longrun if the bangai cardinal doesnt go back will he be fine?
and could i add some type of wrasse such as a mckoskers flasher wrasse?

The banggai will be fine (provided he finds a new spot and the gramma leaves him alone). Mine just "floats" around all over the tank.

I've had both in a tank together without issue. I think the issue is probably not the size of the tank but the rock work. This is the rock scape for my Red Sea 750 to give you a few ideas. At any given time 40 some odd fish are hiding amongst it.
