doesnt it float?... I tried just cutting it up, but I didnt soak it. Thats were I went wrong
Yeah you have to soak it and then mush it up. That way all the air gets out of it. Most of my tangs won't even look at the bigger pieces. They go for the small mushed up stuff. All of my fish have taken to eating nori when I feed it this way even my non algae eating fish like sand sifting gobies, basslets, wrasses etc.
