This is enough to supply all the dietary needs of at least 6 medium sized tangs. I'm a hobbyist. And remember, at any time you can start up a new Tang Heaven farm with healthy, genetically selected starter stocks from Indo-Pacific Sea Farms. It is naturally sun-dried daily on our farmsite on the Kona coast. Use Tang Heaven Nori just as you would use store-bought Japanese Nori.
Healthy tangs tend to graze continuously during the day.
I still have questions. We'll respond promptly with helpful technical advice.
