Coral maybe?

I just seen this in my tank it doesn't look like aptasia to me but I could be wrong. Can someone help. It's in the middle. It's pretty much clear with a bunch of tips with little bubbles on them. It hasn't spread just looks like it got bigger.

The thing in the middle of the indent? That looks like a sponge. The right of the rock has palys on it though.

The one in the indent. It comes out and hides

Oh that! That looks like a majano anemone. Not as bad as aptasia but still bad. You should try to kill it with aptasia x. They will multiply if you leave them there.

Google psudocorynactis

psudocorynactis is exactly what it is. I take it it's bad and get it out of there.

Well most people say kill them. I have three on one of my rocks and love them. They aren't spreading, so that's good. I like to look at them and even feed them. I say it's your call on this one.
