I have an obviously male blonde naso tang, his streamers are starting to develope nicely. What are my odds of adding a female naso and having them cohabitate peaceably? I would love to have a pair of them but I REALLY don't want the one I currently have to be lost. He is head and shoulders above the rest my favorite fish. What would be the best way to go about adding a female if the risk/reward is low enough to do so?
