I bought them because they were paired and Im working on breeding clownfish, but after I read up on how difficult these guys are to breed I figured I could put them in the main system instead, but if they are going badger the tank inhabitants I will have to look for that receipt and return them (Which I hate doing) but Im not going to risk it.
I found a thread on MOFIB heres the link:

Mean disposition was not consistant with my experience with them. They were some of the least aggressive clowns I've kept. I even kept them with other clown species that were smaller without issue.
