Love my royal gramma... was my 2nd fish, got him as a baby. Anything new that goes in the tank he goes right up to, swims with his head straight down and side-eyes it. Picky as hell with pellets though, he'll eat Formula One small pellets (no other size) and spits anything else out (and HATES NLS). And so pretty for such a cheap/common fish! Lotta bang for your buck there.
