I read Jack Wattley's column in TFH where he recommended Discus beginners to get a variety that is more hardy for a starting place. I've had a lot of aquarium experience but have never had Discus. I'm thinking of getting a set of 6 juvies to raise up in a 55g and see if I can get them to pair off. I want a variety that is reasonably pleasing to the eye, as robust as possible for Discus, and would command a reasonable price if I ever got to the point of having raised a successful brood. Any recommendations?
