The clown in question is about 3" and the anemones are much larger than the clown, the LTA we just got was approx dinner plate size. Also the clown doesnt just put the tenticles in its mouth and blow them out, it spits out the tenticles and they are not attached to the anemone but floating...
I'm with the Pistol shrimp crew, I smooth out the hills and he has them back by morning. I would watch to and see if there are small pieces of coral or debris around any cave openings. Pistols like to decorate their burrows.
My Maroon clown for some reason has just about beat to death any BTA I have ever gotten it. It finally seem happy with the LTA but the Clown will bite the tentacles right off the anemones, has anyone else ever seen this???
