Frozen Spinach / Vegetable Diet
Frozen spinach is a perfect source of food for marine herbivores and other tropical fish. Herbivores have a diet that consists of plant materials, and they consume significant amounts of algae and other plants every day. They require continuous grazing, and to accommodate this, food should always be readily accessible.
It's possible that frozen items could partially or fully thaw during shipping, but this shouldn't affect their quality as long as they're refrozen immediately upon delivery.
All our frozen foods are gamma heat treated.
