Green Bubble Algae?

[akriegsfeld]

Hi Everyone,

I am having an outbreak of bubble algae. I have been reading that Emerald crabs will eat it. I have purchased 5 of them but they seem faily small. thebodies are about an 1/2 inch wide. It is a 90 gallon tank. Should I get more than 5. So far they are picking at the rocks but not eating any bubble algae.

All advice Welcome.

Thanks
Alan

It's hit-or-miss with emeralds eating bubble algae. Give them time....
