Made right here in the USA, Repashy Morning Wood is a high quality top choice supplemental food option for your isopods. It's packed with nutrients and can be served as is in powder form or mixed with water to create a gel. Either way, isopods love this stuff! Our 50+ species we culture waste no time to eat up any powdered Repashy diet we offer them a few times a week. Repashy makes numerous other blends that are completely suitable to offer your isopods so they can have some variety.
Please note, while Repashy Morning Wood is a superb option we highly recommend, an isopods primary diet should always consist of dried leaf litter and decayed wood. These two items must always be available in abundance. Isopods have evolved as detrivores consuming any dead plant and/or animal matter they encounter in the wild. Strictly feeding powdered diets may seem logical, but it will not work for isopods. So limit supplemental diets to a few times a week for best results. Mixed veggies and some protein like fish pellets or freeze dried minnows should also be offered on a supplemental basis as well.
