how big is your niger? o, most nigers i see have a tealish color, mine is a very dark blue, is the dark blue color only the juvenille color? err dont nigers change colors?
mine is about 4" he does have some pretty impressive teeth now, he bit me today. i couldn't believe it, he has always been such a nice fish. well, i guess that's what i get for sticking my hand near "his" live rock
