I went cruising the LFS's close to me today. I saw a couple of fish that I'd like to get.\r\n\r\n[I]Clown tang [/I]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.\r\n\r\nI also saw [I]Powder Blue [/I]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.\r\n\r\nSaw a [I]Kole Tang [/I]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.\r\n\r\nAnd of course both LFS's had the famous [I]Yellow Tang[/I] 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?
