I know this topic is old, but I'd say go for it! They are a truely gorgeous fish and has been a wonderful addition to my tank. I have one about 4" along with a 4" Fowleri, 6" naso, 3" sailfin, 5" blue, 4" chevron, 12" vlamingi. I have a total of 8 tangs in my 300g tank and they all get along beautifully! If you wanna see a video of them eating a 1/2 sheet of seaweed, go to youtube and type in "feeding time in the tang tank". That video was only about 2 weeks after adding the pale lipped, fowleri, naso, and chevron. For all the "haters" out there that think I have too many tangs, I also have a 180g sump for a total of about 400-425g of total water volume and all my fish get along great and are all super fat and healthy. So in short, I say get the pale lipped tang, you will love it. It is my favorite fish in my tank. Its kinda plain in comparison to some other tangs, but none-the-less its a gorgeous fish. I really like the orange fin tips.
