So I don't want anyone to think I'm disregarding any advise or information provided to me thus far. However, I see this information on a website for the Blue Hippo Tang:
Description: This beautiful fish is royal blue, with a black palette pattern on the side and a yellow tail. Of the thousands of fish available to the trade, this is one of the most popular of them all! It is widely distributed throughout the Central, Southern and Western Pacific, and like all fish collected from many different locations, quality varies from one collection location to another. Beware of cheap specimens. It is shy, especially when first introduced to the aquarium, and should be provided with coral, live rock, or other suitable shelter sites. This tang will lie on is side (often startling those unaware of it's behavior) if it cannot find a suitable hiding place, or when first introduced into the aquarium. This species is usually more docile than many other Surgeonfishes, and gets along great in a peaceful community or reef tank.
Recommended Tank size: Requires a 20 gallon or larger aquarium with a number of hiding places and plenty of room to swim.To keep multiple specimens, introduce the entire lot at once into the marine system.
Food and diet: In nature it feeds almost entirely on brown macroalgae and should be offered a wide a variety of foods including plenty of algae. Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of seaweed and algae. These are the foods that will strengthen their immune system, reduce aggression and improve their overall health. Offer dried seaweed tied to a rock or use a veggie clip, and feed at least 3 times per week. Sea Veggies, Seaweed Salad and Ocean Nutrition are all ideal products and are very easy to use.
Reef Compatability: Good reef fish
Level of Care: Easy
Approximate Purchase Size: Small: 1 to 2"; Medium: 2-1/4" to 3-1/4"; Large: 3-1/2" to 5"
It looks to me like they're implying that I can keep it no problems in a 125 gallon... however, the power blue tangs information is:
Description:This gorgeous fish is sky blue overall, with a yellow dorsal fin, a white anal fin, a black head and a white band behind the head. It is perhaps the most beautiful members of the genus.This fish will be shy when introduced to the aquarium and will require plenful hiding places to refuge in if threatened. A tank with a flourishing algae crop or live rock will help it adapt to the aquarium. Like most surgeonfish, this species can be aggressive toward surgeonfish tankmates once it acclimates, especially members of its own kind (keep only one per tank). Provide with plenty of swimming room, as well plenty of hiding places.
Note: We ship Powder Blue Tangs in very large bags. Because of this there is an additional $10.00 added to the shipping cost to make sure it gets to you in great shape..

And also claims it's a bit harder to take care of than the blue hippo tang... is this just wrong?
