+1 No problems with fish,but kiss your cleanup crew good bye; mine has also recently taken a liking to my cleaner shrimp. I have went with about 4 tuxedo urchins instead of snails or hermits.
Not sure what they would do with a sea hare.
I tried turbo snails and as I'm placing them in the tank he was up there nipping away. Never saw them again.
It is a great looking fish.
