Powder Blue Tang & Yellow Tang Together??

[adonegan15]

I have a yellow tang in a 100 gl cube tank and I would like to add a powder blue tang. I have a lot of live rock and swimming space but I want to get everyone's thoughts and experiences. Should I add a PBT? If not any other tangs you would recommend?

PBT need 6 feet back and forth of swimming room. The minimum tank I would put one in is 150 gallons.

Yellow tang will be fine.

Other tangs to consider: purple or scopas (if added you'll need a social acclimation box for sure if you only add one zebrasoma tang or tang as an existing isn't likely to welcome another), chevron, kole, etc.

I would avoid acanthurus as they're very demanding with regards to water quality, parasite prevention, and swimming space and also generally very aggressive.
