Quote from RB
New Era has some great food products and the company’s latest offering New Era Mini Marine Grazer rings are highlighted in a couple of videos that might be helpful for reefers on the fence. Anyone with a few hearty herbivores in their system would like these as a tasty treat. The small rings of food are secured to the side of the tank with a simple suction cup allowing the fish to eat at will.

The videos not only show the simplicity of the feed system but also shows the impressive feeding response the food gets from the fish. We can say from our personal experience with New Era products that the food is high quality and have had positive feeding responses in our systems.

Very cool concept... Do you know how slow or fast they deteriate if not eaten. I may be interested in these, but don't want to pollute the water.

With any food 24 hours should be a maximum.
