I am going to go against the grain also. I have a Yello, Powder Blue, and a Sailfin. The other tankmates are a maroon clown who has been about 3 inches long for about two years now(male?), a purple firefish, a sixline, two CLEANER SHRIMP (VERY IMPORTANT WITH THE TANGS), and snails and hermits. I agree that this maybe too much but they are well fed, they each have a cave, and lots of swimming room. I watch the water parameters very closely and watch their activity closely as well. If you are going to add so many make sure they are your main focus until they become very familiar to you don't try a lot of new things.
And of course, this is all IMO.
