Ive had the rock 2 years and in that time it has been the weirdest rock in my tank.

First it started to grow those green polyps after a year of being in my tank.

a REALLY weird sponge grew out of a hole with strings all thru it. Lots of critters.. cool stuff.

Well the last 5 months this algae (i think?) has been covering the rock.

Very slowly. Its starting to grow over the polyps and choke them.
Its ugly brown, and rubbery (was easy to peel from around the polyps, but when on rock i can barely even scrape it.

And i guess this is bubble algae, but not the regular kind..

Im really sorta worried about this brown stuff. I have nightmares of it taking over the tank.

ANY idea what it could be?? ive looked thru algae pages and I havent found anything similar.

Same for the green leafy things, any id?

Thankyou thankyou! :)
