Gifted a harlequin sweetlips

[N.Sreefer]

So my gf comes home with a fish that I at first thought was a lionfish then I realized her well intentioned birthday gift gets 36 inches long and eats fish. How long can I keep this fish in a 6 foot long 150 gal? How long before my clowns and mandarin become food? Rest of my fish are large but I feel like the clowns and mandarin will be prey eventually. I imagine I will have trouble rehoming this fish so I will probably have it for at least a year.

They dont accept returns on livestock, I'm sure I'll find someone to take it that has a fowler but it may take awhile so I'm wondering just how quick they'll outgrow a 6 foot long 150 and how long until fish the size of occ clowns are on the menu?
