ID help please

I have had some tubeworms under my overflow box for months. Now I look this week and I have some new critters that I can't ID. Any Ideas? I hope they aren't majano or aiptasia.

Looks like pineapple sponges by the tubeworms

Yep, that's what they are. Both are harmless filter feeders.
