Green bubbles & wierd disc like thing

[djones169]

Hi guys. I bought this live rock from a guy that I think let his tank go to junk. These are on the good piece I got. The green bubbles concern me. The discs, there are 12 of them. 1-2 mm across.

Green bubble algae. It will get worse if you don't remove it. I tried plucking it but you have to do it without breaking the bubble.

I got some emerald crabs, which are amazing grazers, and they ate it all, and they love macro algae, which I also had. But I really wanted the emeralds, you could take the rock out and pluck it off in old saltwater, then rinse with more saltwater and put it back to see if you got it all off.

I just watched one of the discs move across the rock...

The algae is a problem, as it is all over the 4 pieces I got from the guy.
I have a coral banded shrimp, hermit crab, star fish, blue damsel, moray eel,and a coral beauty angel in the tank right now. Will any of them take a swing at it?

Nothing in your existing tank will take care of the algae but your eel will eventually take care of the fish you have...
