changing flow pattern will make RBTA move?

[DMK]

i've had a beautiful 6-7" RBTA for about a week. it's been settled for about 4 days. it's foot is attatched in crevice of LR. from that crevice it can expand up and out 3 different holes. 1 towards front, 1 towards top and other towards wall in direct flow of MJ 1200. this is my least favorite spot. my new maroon juveniles are cozy here w/ it. if i suddenly shut that MJ off, will it most likely expand through 1 of other holes? without that MJ on, it is a very low flow area. front hole is mod flow. top hole is mod-high. i don't really want it where it is. u can only see about 1/3 of it. besides that u barely see the clowns since they never leave the RBTA.

bump.
i shut down that MJ1200 last night and placed a small rock where he was, after he went in for night. lights come on in an hour. there's a small rock where he was last night and no flow. he should come out in another spot. hopefully 1 of the 2 i want. them damn clowns are in him like flies on shi*!. where ever he is they are.
