Do Acropora have sweepers?


Reef Enthusiast
Just wonder if Acros have sweepers because 2 of ours have had what seems to be sweepers waving in the current from them. Our Super Blue has them all the time.. just wondering if it is sweepers or if something is wrong.
LPS have sweeper and feeder tentacles. The sweepers are used for defense (or in a case that a neighboring coral pissed it off, offense) and the feeders are primarily used for catching, immobilizing and transporting prey to its mouth. They can sting, too, which is how they catch and immobilize their food.
