Emerald Crab?

[tbrown]

Ok, I have a small amount of bubble algae starting to grow on a frag of stylo I got from a friend. It's two bubbles but seems to be shrinking... I've also got a small amount of hair algae growing right in the middle of my tank. Should I get an emerald crab to help or should I hope the bubble algae goes away? Also, will an emerald crab even help at all with the hair algae?
I have a few small frags of Zoas and a couple of sps.

5 gallon AIO
1 clown
1 trochus
1 blue leg
1 peppermint shrimp
2 nassarius

Remove the bubble algae by hand outside the tank immediately without popping it

I still like emerald crabs for prevention I the future. Still remove what you see by hand. But the crabs can eat it before you notice it next time.
