Anyone have any experience with these guys? Curious if they truly get to 5.5" as listed on liveaquaria. I've only kept occellaris/percula family clowns before but thinking about doing a pair in my 270. There is a pair of perculas (onyx and picasso) in a purple carpet in the far right portion of the tank. I'm moving a ritteri over to the left side of the tank and thinking about a pair of spotcinctus versus a pair of skunks.
