Pics, yeah post them up.

Maxi minis can get rather quite a bit larger than that. Maybe you were talking about the similar looking mini carpets? Two maroon clowns hosting it still makes me think its a bta. When a BTA splits into thirds the smaller section usually has a hard time making it. If you or your fish feed them try to discourage this until the mouth has redeveloped. Also the clowns hosting them are going to stress the thirds out quite a bit.
