Oh he's tiny. I thought he was maybe bigger after looking at one of your photos where he looked huge. Guess it was justa really good closeup.
I really like the Nigers .. love their blue colour. I always heard they are sorta hit and miss in a reef? But not sure why or what it is that they reputedly do to earn that "rating." Was thinking if I setup a FOWLR I'd try one. I have a baby (3") crosshatch in my main reef right now and so I'm sure it could not support a second trigger.. I'm not sure my next tank is large enough to support 2 triggers either..
