NorthFin Krill Pro – 85% Krill Color-Enhancing Pellets (1–6mm, Slow-Sinking)

The color-booster serious keepers reach for.

You've tried the color foods that promise the world and deliver a faint tint at best — usually thanks to artificial dyes, not real nutrition.

NorthFin Krill Pro is different: built around 85% whole Antarctic krill meal, it uses the krill's own natural carotenoids and astaxanthin to bring out deep, genuine reds and oranges — no synthetic dyes, in a slow-sinking pellet from 1mm to 6mm for fish of every size.

Krill Pro 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 — here led by whole Antarctic krill, alongside herring and sardine meal and 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.

1. Choose the pellet size to match your fish.
2. Feed 1–2 times a day, only what's eaten quickly.
3. Watch natural color intensify over a few weeks.

Why NorthFin Krill Pro

• Real color, naturally — 85% whole Antarctic krill meal delivers the krill's own carotenoids and astaxanthin for deep, genuine reds and oranges, never synthetic dyes.
• Whole-ingredient nutrition — a krill-forward marine diet supplies highly digestible protein, amino acids, and omega-3s to support condition alongside color.
• Cleaner water — steam-extruded, easily digestible pellets mean low waste and clearer water while your fish color up.
• No junk — no fillers, no hormones, no artificial pigments — just concentrated whole-krill nutrition.

Best For

Any freshwater fish where natural color is the goal — cichlids, bettas, goldfish, tetras, barbs, and more — as a color-enhancing staple or supplement. The slow-sinking pellet is offered from 1mm to 6mm, so choose 1mm for small mouths, 2–3mm for mid-size fish, and 4–6mm for large fish.

Key Ingredients

• Antarctic Krill — high-quality protein, amino acids, vitamins, and minerals, plus natural carotenoids and astaxanthin to bring out rich, vibrant color.
• 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. For the best condition and color, rotate with other NorthFin formulas through the week for dietary variety.

FAQ

Which pellet size should I choose? Krill Pro comes in 1mm to 6mm — pick 1mm for small mouths like bettas and tetras, 2–3mm for mid-size fish, and 4–6mm for large fish, feeding only what's eaten in a few minutes.

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 deep reds and oranges come from the krill's own natural carotenoids and astaxanthin plus spirulina — never artificial pigments or dyes.
