Bubble alage on coral

[TheWalkman99]

Bought my first piece a coral ricodria and Zoa on a piece of live rock at my LFS for $35. After getting it home I saw one little bubble alage on it before I put it in the tank. Took it back to the store and he put it in the emerald crab tank for me.
So question is are emerald crabs that good at cleaning bubble alage?
Or should I find a different coral? My LFS said he would change it out.

Emerald crabs are really good at getting rid of bubble algae

Good catch on seeing the green bubble algae.. I wouldn’t put that piece of coral in the tank. People say the emerald crabs would clean it out.. I had no luck with them.

Guess I’ll just have to see what it looks like after a few days with the emerald crabs.
And it wasn’t I have to have it coral luckily
