Hammer sweeper tentacles

[Rmckoy]

We have had this hammer for about 9 months, and Xenia has been very near it for at least the last 3. Suddenly, over the past few weeks we’ve seen these tentacles, increasing in length and quantity, all coming from the right side of the coral as pictured. The closest Xenia are taking a beating.....

Those look like sweepers to me . Kinda goes against what I have been hearing that hammers don’t have sweepers lol

You’re going to have to move one of them. And I would vote move the xenia. The hammer is going to kill whatever part it touches and your xenia is going to start detaching parts of itself and start spreading to parts of the tank where you don’t want it. If you don’t keep an eye on it it will take over the tank.

Do Sweeper tentacles always come out of the top of the colony ?
I knew it was one if the euphillia killing the neighbouring Xenia but not sure what one .
I have a purple tip hammer frag sitting inside a rock .

is it sweepers or worms ?

Could be a tentacle of a spaghetti worm. But i dont think that would cause your xenia to shrivel, it could be that your hammer stung in when the lights are off.

Hammers don’t have sweepers per say, they elongate one or more of their regular tentacles. It’s really obvious. Galaxea, chalices, pavona, leptiseris, and some others have sweepers. They look almost transparent and obviously longer than their regular tentacles. My galaxea has 6 inch sweepers that come out of a
2 1/2 inch colony. That stuff that looks like tentacles coming out of the rock are something else.

Sweeper tentacles or waste?
