You should get the regular cherry barbs instead. The males are very impressive once they're ready to breed. Imo, a male cherry barb in breeding condition is far more impressive than a neon or cardinal. If you want brightly colored fish, get about 10 cherry barbs (5 females, 5 males). I plan to have at least 20 of them in my 70 gallon tank. Or none if I decide on angelfish, but I'm leaning towards the cherry barb swarm and some gouramis.
