White stuff growing

[Bankertanker]

Hey everyone,

Does anyone know what these little white stuff that are growing on the rocks,

What is the cause of them?

And how do (Or should I) get rid of them?

Thank you!

Pineapple sponge - let it stay or nuke?

Guys, earlier today I discovered pineapple sponge that was bothering my zoa. Removed that one, then later researched and found out that many people say its actually very good for the tank and arguably more rare than any zoa. Well, I just found another one, about the size of a nickel on the back...

Agreed, they are pineapple sponges. I have them and IME they are totally harmless and stay in shaded areas.

Later in that thread the OP posted a pic of a sponge that was growing on a coral. But, it appeared to be some type of a ball sponge and not a pineapple sponge. I think pineapple sponges are too small to smother anything and as far as I've seen, don't grow in dense groups.

The ones in my tank are growing really fast and there's a lot as well.

They're pretty easy to remove. I had some on the back part of a powerhead so I just plucked them off with my hand because they were kinda ugly against a black background.
