User blog:Yeit/Just a question on Vander Decken IX.

Wait so we all know he's a fishman that can't swim. But he still a fishman...so can he still breathe underwater? or not? Or is it because the devil fruit powers makes him weak in water, so he can't breathe? Either way he still should be able to breathe underwater cause he still is a fishman, all fishmen and mermen have gills,...am I correct?
