need identity of green things on live rock

[ryan0292002ca]

I've had a 30 gallon saltwater tank setup for about 10 months now with 20 lbs. of live rock, 2 clownfish, 2 hermit crabs, and 12 snails. Recently I just noticed shiny small perfectly round dark green balls attached to my liverock in clusters. Are these eggs from the clownfish? or are they something growing from the liverock, and if so does anyone know what they are? thanks in advance

Sounds like it may be bubble alge but hard to tell with no pics.

Agree - sounds like bubble algae.

I also believe it sounds like bubble algae (valonia)

you can carefully pull them off the LR without popping them to get them out of the tank.

 

[i have crabs]

dont pop them they spreed like crazy if you can have a emerald crab it might eat them

I pick them out with my nails, if you do not have nails try prying them out with something skinny, but do not pop them, you'll get a lot more if you do.
