Getting new fish. Advise!!!!

I am going to pick up a Starry Blenny on Wednesday. I have a 29g biocube about 2 months of with 4 snails, 1 emerald crab, and to much green hair algae. Will that algae be enough to sustain his diet? Or will I need to go buy more food to put into the tank?
Im also picking up a cleaner shrimp.
Thanks

 

I don't think a starry blenny will consume gha. Sea hares will consume gha. what are your prams?

 

Should be fine. What are your params? Is your tank done cycling?

 

Get some nori to supplement. Hermit crabs will help knock it down. You may need to rotate the hermits in and out mine seem to leave the bushy stuff after a little while.

 

Sorry im still new here. Only second post. Params? as in parameters?

 

my ammonia, nitrate,nitrite are 0. Ph is 7.8

 

Anything?
