Feed your predators like they'd eat in the wild. Big carnivores — large cichlids, predatory catfish, oddballs — need serious protein to hold their color, condition, and growth. Fillers and grain-heavy pellets leave them hungry and washed out. NorthFin Carnivore Formula is a high-protein, marine-based diet in a hearty 10mm slow-sinking pellet, made from quality proteins with no artificial dyes. It sinks slowly so mid-water and bottom feeders both get their share. Carnivore Formula comes from NorthFin, created by Darius Chodocinskas, an aquatic specialist with more than 30 years of experience who grew frustrated by the fillers, hormones, and artificial pigments in ordinary fish food. NorthFin is built on whole-ingredient marine nutrition — whole Antarctic krill, herring, and sardine meal, plus whole organic kelp — steam-extruded and made in Canada to preserve nutrients, stay easily digestible, and keep your water clean. No fillers, no hormones, no artificial pigments or dyes. Feed 1–2 times a day. Offer only what your fish finish in a few minutes. Scoop out any leftovers to keep the water clean. Give them the meal their size demands. Add to cart. Why NorthFin Carnivore Formula Real color, naturally — Antarctic krill, astaxanthin, and spirulina keep big predators richly colored using natural carotenoids, never artificial dyes. Whole-ingredient nutrition — a marine-based, high-protein blend of whole krill, herring, and sardine meal fuels the growth and condition large carnivores demand. Cleaner water — steam-extruded, easily digestible pellets mean low waste and clearer water even in heavily stocked predator tanks. No junk — no fillers, no grain-heavy padding, no hormones or artificial pigments — just concentrated whole-food marine protein. Best For Large predatory freshwater fish — big cichlids, predatory catfish, arowana, oscars, and other carnivorous oddballs that need a high-protein diet. The hearty 10mm slow-sinking pellet suits large mouths and lets both mid-water and bottom feeders get their share; for smaller predators, pair with a smaller NorthFin pellet. Key Ingredients Antarctic Krill — high-quality protein, amino acids, vitamins, and minerals, plus natural carotenoids and astaxanthin to bring out rich, vibrant color. High Omega-3 Herring Meal — top-grade fish meal with a higher concentration of DHA for healthy development, growth, and coloration. Certified Organic Kelp — marine seaweed supplying roughly 60 minerals, 21 amino acids, and 12 vitamins to improve overall health and activity. Spirulina — natural blue-green algae rich in protein, vitamins, and minerals that supports immune function, with natural pigments for color enhancement. Calcium Montmorillonite Clay — provides 67 minerals and essential trace elements to help correct dietary deficiencies. Feeding Feed 1–2 times daily, offering only as much as your fish will consume within a few minutes. Remove any uneaten food to keep water quality high.

Feed once or twice a day, offering only the number of 10mm pellets your fish finish within a few minutes, then scoop out any leftovers to protect water quality. Will it cloud my water? No. The pellets are highly digestible and low-waste, and they hold together as they slowly sink rather than breaking apart and fouling the water. Are the colors from dyes? No. The color comes from natural sources like krill-derived astaxanthin and spirulina — never artificial pigments or dyes.
