Little White Sponges

[LINK]

I have a ton of little white sponges that look like little barrels with a flared end. They grow out from my LR and seem to be popping up everywhere, anyone know what these are, or if they are anything to worry about?

i've got some of those too. i've even got them growing in the return portion of my skimmer. i'm also curious to see if they're a bad thing.

Claw-
These sponges are very normal and often very numerous in newer systems. I had a zillion of them for the first few months, now I only have a few. They are filter feeders and won't hurt anything.
Good Luck

in fact, those sponges are a great thing. as mentioned above, they are excellent natural water filters. consider yourself lucky - wish I had some in my reef

Claw:

I have had these for almost two years. When I asked what they were someone replied glass sponges. I am not sure if that is correct but they certainly seem harmless. I had many when the tank was young a little less now. They seem to like the darker areas.
