I've had this weird growth on my acan for a bit, not really worried about it, but figured I'd share a pic and see what you guys think.

Looks like a sponge to me, probably nothing to worry about.

Thanks for the info zenoxa, I can stop worrying about it now. I've gotta say, I've never really paid attention to what a sponge looks like on an acan before, so that's good to know for future reference.

My rocks are loaded with these on the underside, they're harmless.

Looks like a pineapple sponge, pretty sure that's what it is.
