Che,la mayoria de productos son lo mismo,yo uso sushi-nori.
i like the ocean nutrition brand because it is soaked in garlic first. you can get purple, red, brown and green i believe. as far as to what variety is best i think it varies between fish. i know my tangs like the green, i think the brown or red is softer and better for angels? i am not sure. hope that helps a little
The only difference is that nori seaweed has no nutricional value at all. That is why i asked wich ¨comercial¨ seaweed had the more fenificial added (vitamins, minerals, garlic, etc etc)
If it didn't have any nutritional value there wouldn't be a need to feed it to our fish at all. I read in a book recently that 100% of the algae eating fish that were taken for our hobby and were dissected had all algae in their gut when they were dissected.
