Anenome Id's Please

[95harley]

I picked up some LR a week or so ago for a new tank and I've spoted about 10-12 Anenome's on various pieces in various sizes. The LR is Florida LR and I didn't think they had Aptasia. But it sure looks like it. Should I be concerned? This is for a FOWLR tank so I'm not worried about corals, but I would hate for my fish to get stung or to get the tank taken over by them.
BTW, this will be a large Agg tank (lions, eels, grouper, tusk, queen angel)
Thanks for the Id's...some are brown, some are clear/white, and some are striped brown with white rings.

And finally

All of them are Aiptasia.

Thought Aiptasia was a Pacific problem anemone, not an Atlantic species.
Do they casue issues on a FOWLR tank? Do they do more good than bad as far as filtering water.
Trying to decide course of action.
Include Racoon butterfly into stock list or let them be and add extra filtration from high output predators.
Risk to livestock?
Sorry for the questions, these are my first Anemones.

They can sting fish, but probably won't until they get to be larger or more prevalent. They can also multiply faster than rabbits so a small problem can get out of hand real fast. Personally, I just think they are ugly and would try to get rid of them. I'm going to my LFS tonight to pick up some Joes Juice to work on mine with. I've been trying the hot water + syringe trick, but the little buggers retreat faster than I can inject them w/ super heated RO (10 min in a microwave on high)

The risk to large fish is minimal. The major problem is that they will eventually cover every surface of every rock.
The Caribbean is also home to Aiptasia.

I read that the Queen Angel will eat aiptasia. Can anyone confirm?
I don't mind letting them be if they are a food source and possibly have some filtering benefits.
