I have two pairs of ocellaris and they bite. My original pair used to be really mellow so I was smug about that. However after they were moved to the small tank, they got very territorial (they have no interest in hosting and just sleep on the sand). The bigger one started biting which is SO annoying in a small tank. I think the size of the tank definitely makes a difference. My pair in the big tank, the larger one bites but very lightly, more like a tap, and only if I'm close to their nem. The smaller males don't bite.
I would still be sad though, as I do get very attached. My first pair were my very first fish so I didn't re-home them - I set up the small tank for them.
Btw I like these gloves as they're quite tough and have a better fit. I had to order them from the US before but recently they started carrying them at Lee Valley.
