With that said, I have one in a 29 gallon with some other more aggressive fish and some soft corals and LPS. I just have to do more frequent and larger water changes to keep water quality in an acceptable range for the corals and reduce algae, as these fish are messy PIGS!
Me and my coworkers do really enjoy having him and his tank mates, just a little more work due to the nutrient levels in this type of tank.
Edit: You will need a tight fitting lid. While I have not seen mine try to escape, they are well known to be quite the escape artist.
