No mate but I know the seller pretty well and have had a pup direct from the female you're buying - pup was a retic X mm.Yes that was me, are you the seller ?
Unless I'm mistaken, the Ray was bred by Richard at Wharf, from mini parents. If in any doubt at all I would contact him. Saying this, the seller is a friend of mine and has only ever referred to her as a mini.
I've not seen her in the flesh, but have seen plenty of video and pics of her over the last year. She's a quality ray no doubt.
