I leave a noris sheet out for my tangs and rabbitfish almost every day. Not a whole sheet or anything, just a one by one inch square. I even will put out more than one in a day if they are being extra piggish. lol Like X said, a varied diet is best, I also feed daily mysis, brine, bloodworms and pellets. You may find the other fish in the tank also eat the nori, my filefish absolutely love it and so do some of my wrasses. Go figure. LOL

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
