I don't have any RCS, but I do have a ton of swords, a trio of marigold, 2 neon females, a neon blue pair, and a young group of northern mountain swords (wild type/captive bred).
All are pure-bred, they probably have platy lines way back, but not anytime in a few generations
Please PM me if you are interested in any/all of them and we can discuss price.
