When I started this thread I was concerned I wasn’t feeding my tangs enough Nori. I actually seem to be feeding as much or more than most others. Something else I have noted that might be of interest to some. My tank is still young, and I’ve recently increased the light intensity because I’ve introduced SPS corals to the system. Algae is not a problem “yet” but it is gradually increasing.
I watched my Tangs and how they spend their day and noticed something that kind of gave me an Ah Ha moment. I usually would put the Nori out early afternoon. About noon, the tangs would stop grazing and go over and hang out where the Nori clip is. Once I put it out, they would pretty much destroy it, but then they wouldn’t graze for the rest of the day. Result……algae started getting thicker. Decided to cut them off and see what happened. From the first day of No Nori, they spent the entire day grazing the rocks. After a week now, the is practically no algae left on the rocks in the tank.
I will give them a Nori treat maybe every 3-4 days, but I’m liking what I’m seeing by not over doing the free food. They are doing a better J.O.B. Of keeping the rocks clear of algae. It is fun watching them go after the Nori, but I guess even fish get lazy when they get free stuff. It’s also fun watching then keep the rocks clean.
