Thanks much SushiGirl
Some kind of anemone or coral?
ArrowCrab, it's a ball anemone. Some people say they aren't that bad, but they have infested my tank badly, I mean at least 30 (probably more) in my 55. They irritate the crap out of my zoas. I tried injecting with lemon juice, kalk slurry, and finally white vinegar. The vinegar is working, so I've been after them once a week. I'm going to start hunting them at night when they are really extended.
TheKman, just a regular featherduster & could be hair algae. Are they both on the same shell? Either way you can scrub the algae off with a clean toothbrush in some tank water in a bowl & rinse it off really well in the tank water.
It won't get large enough to host clownfish & they're not a true anemone but Pseudocorynactis, more related to mushrooms. If you could manage to remove it you could put it in the sump, but like aiptasia, any piece you don't get will grow another. They don't sting as bad as aiptasia or majano, but they do sting. My zoas hate them & will not open then wither away because they're closed & don't get any light. I cringe every time I hear someone say to leave them because they won't spread simply because I know first hand just how much of a plague they can be LOL. I started with one that I missed on a frag I got from someone local, and I decided one wouldn't hurt based on people saying that. That was a little over a year ago, and after looking last night after the lights went out I realized that I have much more than my last guess of 30. 2 months ago I counted 25 that I could see & that was with the lights on & only in the front of the tank.
My understanding is that this is the only way they reproduce, so if that's the case they wouldn't manage to get from the sump to the DT through the plumbing...well, unless they get through your pump because they do move around. Not sure what would happen if the pump chopped it up.
I just went through some pics I took the other night & got a pic of one spreading to create another. There are actually 4 in this pic.
