No ramsey is a boys name, i know thy'll be some territory issues but hopefully that will decrease in time
It seems a lot of myths are surrounding bumblebee gobies about how difficult they are to keep in non brackish conditions and that they are picky eaters. Well I can tell you that they are not! Great fish, one of which is very very active in open water and loves to swim up to the top then bottom of the tank constantly and very fast 
I think you might be right on this one!
The Brachygobius xanthozona has perfect unbroken black stripes and is best suited for brackish, but will tolerate fresh water much better than the Brachygobius nunus which has less well banded stripes, and occasionally black spots or broken stripes. It is not very tolerant of a fresh water environment. Technically its common name is the Golden Banded Goby, although I have not once seen these two species clearly distinguished when on sale in fish stores. They were for sale as freshwater BBG's in a lfs that also stocked brackish varieties
