Repashy Grub Pie (Fish formula) is a high-protein insectivore gel diet built for insect-eating fish. Black soldier fly larvae lead the recipe, giving bettas, gouramis, killifish, and other bug-loving fish the meaty, insect-based nutrition they would hunt for in the wild. Explore the rest of our fish foods. Why Repashy Grub Pie Insect-protein rich: black soldier fly larvae and other insect meals match the natural diet of insectivorous fish. Great for picky carnivores: the aroma and soft gel texture tempt bettas, gouramis, killifish, hatchetfish, and archerfish. Conditioning staple: high protein to support color, growth, and breeding condition. Cleaner than live or frozen: a shelf-stable alternative to bloodworms and other live or frozen insect foods. Easy to portion: cut to size for nano tanks or full community setups. How to Prepare Grub Pie ships as a shelf-stable dry powder. Mix 1 part powder with 2 to 3 parts hot water, stir, and let it set into a firm gel (about 5 minutes). Cut into pieces and feed. Refrigerate prepared gel for up to a week, or freeze it for longer storage. This is the Fish formula; Repashy also makes a Grub Pie for insect-eating reptiles and amphibians.
