Needing some suggestions on a fish to help with a small green hair algae issue. Tank is a Biocube 32g mixed reef. Any recommendations would be appreciated
 
Please describe your GHA issue a bit more in detail.
Is the tank new? Was it started with dry rock? Do you have any other fish? If so, what kind?

Is the GHA very long or more turf like?

Do you know you nutrient levels?

Photos would help.

I have a total of 5 spots like this in my tank. I have 2 clowns, a flame hawk, and a pj cardinal. I have roughly 15-20 hermits and 10-15 snails plus an emerald crab for clean up. I just did a 5 gallon water change. nitrates are at a 15 right now. Tank is pushing almost 1.5 years. I have upgraded my lighting to an ai prime 16. Flow I use a Nero 3 and an axis 40.
I will say all my coral see happy but my gonis and green slimmer.
 
The absolute best critter for gha is a seahare, my son’s 55 g was infested and in 10 days it was completely gha free. It won’t take long in a 32g so be prepared to rehome it. While it’s doing its job try to correct the issues causing the problem.

Oh, that’s not much at all. Manual removal.

This is what the tank looked like before I picked it up from Facebook marketplace. It was covered in green hair. I got it all gone and now just a few small spots have came up. It’s been gone for 4 months now and just popped up
 
Tuxedo urchin has been amazing in my 40B so far... but I would agree with manual/toothbrush as well.
 
I would just beef up your cuc, use a bristle toothbrush, and your hand to remove the GHA. You luckily don't have a bad case of GHA, so it should take no time to remove all of it!
 
I can't think of a Fish that would fit in your Tank that will eat GHA. In fact, there really are no fish that will eat GHA as it's too bitter.
 
I agree with everyone,, in this case manual removal is probably your best bet. If you wanted to get extra thorough and are able to, you could also take the rocks out of the tank and apply peroxide directly to any remaining bits as well.

Also just for the sake of conversation, I second a sea hare for GHA removal, but as mentioned, prepare to rehome in fairly short order, and just keep an eye on it in general. This was years ago, but I put one in a 10 gallon that was overflowing with hair algae with the intention of removing it after it had cleaned the tank up. I left over the weekend once and it died while I was gone, and it completely nuked the tank.

Another personal opinion, but a links goby might be an option to look at as well. It would fit fine in a 32 gallon, and I have seen them happily munching GHA before. Mine will eat it if its in the tank, and they have the bonus of being a light duty sand sifter as well.
