jeez, I'm kind of ruining your thread here aren't I?
I feed the fish a 1cmx1cm chunk of frozen mysis every day. I thaw it out and drain off the liquid before I feed it. I used to feed a 5cmx10cm chunk of nori every day but have since stopped doing that and only feed it about 2x a week now. If everyone ate nori I'd stop with the frozen.
Currently I have a 4" regal tang, 4" scopas tang, 5" tailspot wrasse, 3" bangaii cardinal, 2-1" neon gobies and a 1-1" lined blenny. Mostly the frozen food is for the cardinalfish, he's a picky little bugger.
