The Ultimate Tang food! These are the best thing you can feed your tangs. Tried tested and used by the pros at Reef Wholesale, this is what they use to fatten up your fish before this shit to your LFS.   For best results there should ALWAYS be a sheet of nori in the tank. Have you notice3d that you feed your tangs and they go crazy and tear up the sheet right away? That's because your not feeding them enough! Day and night there should pretty mush always be a sheet of nori in the tank. This will help you keep your iodine levels up too! To stop the sheets from breaking down and blowing around the tank, we recommend you use the Two little fishies Pouch feeder.   This is an algae that we discovered on our trip to Japan.   Each sheet is a blend of two types of algae in each sheet. No need to feed multiple types of nori to keep your fish happy and healthy. Check out the pic of our nori at 1500 times magnification. You can very clearly see two totally different types of algae in each sheet.
