Agreed. If you catch something in the wild and they begin depending on you for food, it's never good to release them back into the wild... at least this is true unless you're an expert at Sea World or similar
Anyway, yes, the Queen Angel will get HUGE really fast, so if you are able to, I'd try and see if any LFS in the area will give you credit for her, or maybe if you have a friend that has a big enough tank, give her to them...
Also, it may not be good to put fish directly from the ocean into your tank. They may have parasites that you don't want to infect your tank with. If you are allowed by your state to catch and keep the fish you catch, I'd highly suggest a quarantine tank (QT.)
And, reiterating what someone said above, definitely check on your state's laws about taking things from the ocean... you could wind up in big trouble.
Good luck!
