I have no idea what this is. As you can see they look like a green bubble almost plastic looking. There is about 4 of them in my tank and the first one I noticed a while ago has gotton bigger. It is about half the size of a dime. Any help would be great:)

Looks like its the first one on the list. I guess I should try to get it off. It says to use a sharpened screwdriver. But if I break it I'm doomed!!!!!!!!LOL Wish me luck. Wait a minute I wonder if I would be better off taken the hole rock out and removing the bubble then rinsing it with the water i take out for my water change.
 
I didn't realize it was a bad thing...I would think it would oxygenate your water...?
 
mynthrax (emerald) crabs eat it.

you can "scrub" it off.

but its not "favorable"
 
lol really it spreads? I think I pop a few and does'nt seem to spread...yet. lol looks fun to pop anyways.
