I saw in my LFS, it was a bottom dweller, very small, maybe 1/2 an inch to an inch. It was a blue and yellow mix, if I recall correctly it was blue towards his head and yellow around the tail, but not sure exactly. But it was definitly blue and yellow. The guy at the store told me it was a brackish. Im cant remember the name of it and am trying to find some info on it. Anyone have any idea?
