I have these small white things growing on my LR. They kinda look like doughnuts. And also, that white tube thing. It came on my LR and looked like it was dead. In 2 months it has doubled in size although I've never seen anything come out the "mouth". Any ideas?

Little round things Spirorbis sp. harmless filter feeders, will come an go with available nutrient.

The long white thing looks like a sponge.

Man you're fast. That's why I love this site. Yep, they're deffinatly Spirorbis sp. thanks! Also, with the long white thing, the clear end is open. Kinda looks like a fancy vase with the way it's shaped. I just thought I'd post that because the pic isn't the best.
