It is NOT unheard of to house these two fish in your tank. Please understand. Don't be scared out of having beautiful, colorful community members by neuroses. :headwally:

"The Sailfin Tang needs a bigger aquarium and should
not be housed in tank smaller than 40 gallons of water. It is a hardy and tolerant species who thrives well in a temperature range of 74-82 degree Celsius and pH range of 8.1 to 8.4. The Sailfin Tang feeds chiefly on leafy macroalgaes, therefore natural growth of algae should be encouraged in the tank by incorporating live rocks."
"Powder Blue Tang has a scalpel at the base of their tailfin which is very sharp and is used by the fish for protection from predators as well as a way of establishing itself with other saltwater fish.Powder Blue Tang Care: It is a fast-swimming vigorous fish that needs plenty of room so it would be
recommended to keep in aquariums of 90 gallons or more with hiding places like live rock. The Powder Blue Tang like most all other surgeonfish are herbivore and marine seaweed and algaes should be part of their diet."
