do emerald crabs eat bubble algae?

[new reefer 03]

i thought they did, and i used to have alot of them just because they looked cool. not i am having a lot of red buble algae pop up, and i need it gone. it looks horrible. i just wanted to make sure they ate it, before i ordered alot of crabs lol.
Also, how many would you recommend for a 55 gallon tank? there are hundreds of small red bubbles

I used to have some bubble algae and my emerald crab got rid of all of it.

My Emeralds ate green bubble algae, I didn't have any red bubble algae so I don't know... but I wouldn't get more than 4 or 5 in a 55.. IMO

I bought am emerald to fight off red bubble algae and he did not eat it.
I have heard it is hit or miss with emeralds eating bubble algae

Normally they will eat it and eradicate it from the rocks completely but some are picky like golden said.
I had a friend that was overwhelmed by that algae and one emerald crab cleaned the whole tank in under a week. It may have to do with where the crab originated from that makes the difference.

I have had emeralds eat the green bubble, but never the red bubble. IMO, the red is much harder to control than the green too.

my emerald doesn't even eat the hair algae( not that ive seen)
With emerald, about 1 per 10G is ideal
