I currently have an adult Chevron Tang in my tank that is my favorite fish. Aside from the Chevron I have all Anthias and a few Chromis - everyone gets along just fine. I recently went to a larger tank and I've been thinking about adding either a Gem or a Powder Blue tang. I've had a Powder Blue in the past - however I've never had a Gem. I guess I'm looking for a Tang that would be "more likely" to get along with the Chevron - anyone one have any thoughts?
