mobert:
I looked at the video of your anemones with less circulation and the one with more circulation.
Monday I installed a Hydor Koralia Magnum 8 (3,250 gph) on the left end about five inches below the water line and one to two inches in from the front glass.
I aimed it toward the center of my five foot tank with a very slight upward direction.
My red BTA decided it liked the high flow created by the Mag 8 with a 175 gph penguin power head with sponge prefilter in the lower right corner to off set the Mag 8's flow on my Green Goniopora on the left front substrate. Everything worked like a charm and the tank seems more alive and healthy including corals, crustaceans, and fish. I just put a true red goniopora on the front right substrate.
The brown/gold (How do you tell the difference) BTA which is about one inch when open, is sticking its little mouth up from the top of one of the rocks.
One strange things was my green BTA has shrunk back under the live rock in the back right corner. I could barely see its tentacles, maybe it is expelling waste as it ate razor clam on the weekend.
My Long Tentacled on the left side reached out and snapped up one of five one inch black mouth damsels I purchased for $5 a piece over the weekend.
The increased current must increase appetite?
