Nano-friendly Bryopsis eating info needed!!

[chemistmike]

I have Bryopsis in gametophyte form starting to spring up on all of my live rock. I have some strands that started out three days ago, and now some strands are about 4" long. I have some hermits and snails in the tank, but I need somebody that can work the tank faster. Is there a nano-friendly fish that I can use that is interesting (colorful or personality)? I have a Biocube 29.

Thanks for the help!
