This is our 1 ounce or 30 gram resealable foil size. This is a good size for aquarist with 1 or 2 aquariums for about a month of feedings. We feed the Endlers and Guppies here 2X daily at dawn and dusk. Livefins blends the ‘Captain Munch’ food here specifically for Endler and Guppy fish. It contains a high quality flake along with Dried Daphnia, Tubifex, Silk Worms, Black Fly Larvae, pearl larvae, high protein fish meal, astaxanthin, spirulina and a few other ingredients, no preservatives. I am in the process of adding the food to my site and will have to let you know once it’s on the site. They also receive spirulina wafers, live mosquito larvae, scuds and daphnia.
