Jaysee: You are correct: the normal rosy barb is olive on the back. Not a good ornamental pond fish. It has to be the neon version: that's exactly the feature of this fish that makes it so outstanding as a resident for a small pond. The males are red dorsally, as well. Several years back, Tropical Fish Hobbyist did an article on other aquarium fish besides goldfish for outdoor summer ponds. This fish won by a landslide. They tried african cichlids, too, and decided that the red zeb ras and yellow labs were really the only "good ones" for this purpose. Blue cichlids didn't show up at all.
The Neon Rosy isn't distorted or deformed or balloon bodied or souped up with long fins which are all things I really HATE about contemporary varieties of fish. But the males are incredibly beautiful from above in the neon red version. The only problem is having enough tank space for the progeny when they come indoors in autumn.
