dont do it. two tangs in that size tank will fight. purples are very agressive, and blues are super ick-prone. that purple could chase your blue around, then the blue would get ick and you have a huge problem to solve. just stick with what you have. if you want another fish i would suggest a pygmy angel if your tank is mature. you can get another fish in there if you want one. look into grammas, blennys, gobys, pygmy angels, hawkfish, etc if you want another fish. i would also reccomend investing in some good books if you dont have any yet. do a search in the fo forum, you will find plenty on them. hth, bo
