I went cruising the LFS's close to me today. I saw a couple of fish that I'd like to get. Clown tang looked real healthy in the tank and was only about 3 inches. Did a little surfing and realized it can grow to 15" and needs a lot of swimming space. So this one is a definite no go for my 4ft tank. I also saw Powder Blue that also looked healthy. Average adult size is around 9" and this was is also aroun 3" or 4" so it should be fine in my tank. I really like the looks of this fish but things I've read say you can show the fish a picture of ich and it will break out. Saw a Kole Tang and this seems to be the perfect fit for my tank as it's one of the smaller tangs. But it just did not have the cool factor to me. I would like to have more colorful fish. I suppose I can add something a little more eye catching with my next purchase. I've got a decent amount of algae growing on some rocks some I'm sure he'll have a field day munching away. And of course both LFS's had the famous Yellow Tang that I was originally planning on buying. I'd love to buy the Powder Blue but I'm thinking it won't be a smart first purchase. Feel free to tell me I'm wrong about the powder blue. So I guess I'm down to the Kole or the Yellow. If I buy the Kole can I add a yellow or some other tang, maybe the powder blue later?
