NorthFin Tropical Sticks – Floating Staple for Oscars & Large Tropicals (3mm)

A staple your Oscars will rise to the surface for.

Big South and Central American tropicals — Oscars, Severums, large cichlids — are greedy eaters, and low-grade sticks leave them dull and the tank hazy.

NorthFin Tropical Sticks are a floating 3mm staple diet built for exactly these fish, with marine protein and natural color enhancers and no artificial dyes or fillers. Floating sticks make it easy to watch every fish eat — and keep an eye on their appetite.

Tropical Sticks come 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.

1. Feed 1–2 times a day.
2. Offer only what's eaten in a few minutes.
3. Skim off anything left behind.

Feed the personalities of your tank. Add to cart.

Why NorthFin Tropical Sticks

• Real color, naturally — Antarctic krill, astaxanthin, and spirulina bring out the rich color of large tropicals through natural carotenoids, never artificial dyes.
• Whole-ingredient nutrition — a marine-protein blend of whole herring, sardine, and krill meal fuels the growth and condition greedy large tropicals demand.
• Cleaner water — steam-extruded, easily digestible floating sticks mean low waste and clearer water, and let you skim off anything left behind.
• No junk — no fillers, no hormones, no artificial pigments — just whole-food marine nutrition for your tank's big personalities.

FAQ

How much should I feed? Feed once or twice a day, offering only as many 3mm floating sticks as your fish finish within a few minutes, then skim off anything left at the surface.

Will it cloud my water? No. The sticks are highly digestible and low-waste, and they hold together as they float 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.
