Naso tang, rabbitfish or sea hare?

[Snappy]

Doug the naso is a 99% guaranteed solution for keeping those varieties of algae in check. I have yet to find a foxface or other rabbit that will do the job. The Naso is a safe bet and as stated by untamed, other tangs don't seem to get aggressive with them like they do with other tangs. Well at least this has been my consistent experience with them.
Good luck,
Greg
