Here's a few fotos of Mexichromis porterae. As I was trying to photograph the nud, there was quite a bit of surge and it lifted up the mantle, revealing the underside of the critter and its oral tentacles (I'm guessing).

Yes the flattened triangular shaped flaps are its oral tentacles. Most chromodorids have more tapering cylindrical tentacles, so this is an interesting observation. I don't think its a character of the genus Mexichromis however, because species I am familiar with from the Indo-West Pacific don't have this shaped oral tentacles. I guess its another thing to add to the 'to check up' list.
