My LFS (Phishy Business) sold them as Venautu veil finned clarkiis. I've also seen them sold as Red Sea clarkiis. I haven't seen a full grown one though to know if the size of the fins remains so pronounced. They are gorgeous juveniles, but I'm wondering if they will grow into their fins in time, similar to the way some of the other clarkii complex fish who start out with long fins do.
