which one is better for my 20gL?

[cubanheat1]

I currently have a 20gl reef setup up.i have a pair of ocellaris percs and want to introduce a small anemone to my tank. my ? is if i have a few corals which will be better a small BTA or a small sebae?i saw a nice 3in rose,and a small white with bright purple tip sebae.Which of the 2 when place will move least?i setup up the left side of tank with no coral for the anemone,does it depend on flow an lighting?Will they stay stationed in the front were most of the light is and good flow?ive seen small tanks with little anemones for the clowns and these tanks look stocked and great, i just dont want it to destroy the coral i have.
Thanks

they arent fans of good flow but good light yes.

Ocellaris usually wont hose either. Mine only hosted a carpet.

The anemone will find a spot he likes, not where you like.

A BTA would be a better choice. They are a bit easy to keep and sebae might get to big for a 20gal. Ocellaris can use the BTA as a host, they don't only use carpets as hosts, I've seen them in BTAs and LTAs as well. And when placing the anemone in a spot you like, try feeding it. That works for some people to get it to stay in a spot.
