Hello everyone, this is my first post on this forum so hello again. I have a 90ga tank with a yellow tang, blue tang, sailfin tang, green manderin, maroon clown, dottyback, and lots of corals. I really would like to purchase a Naso tang but the people at the fish store say that it might fight with the other tangs. Whats the possablitly that this might happen? Also, I am fairly new into the marine fish world so is there any fish that are reef safe, gets along with my tangs, and are beautiful? Thanks for your help.
