You have a mixed reef tank with fish that all need feeding differently. Anthias, clownfish, chromis, wrasses, gobies, damsels — each one a little different, each one looking for food the moment the lights come on. Trying to rotate several specialist foods every day adds complexity most keepers simply do not have time for.

The result is often a compromise: one food that suits some fish reasonably well, but leaves others short on what they actually need. Over weeks and months, that nutritional shortfall shows. Fish become duller. Less active. More prone to illness. It rarely looks like a feeding problem, because it happens so gradually.

Reefphyto Marine Flake Premium is a complete daily food formulated specifically for marine fish. At 48% protein with a full B-vitamin complex including B1, B2, B6, B12 and Inositol, plus algae inclusion for the plant-based nutrition reef fish also need, it is designed to cover the full spectrum of a mixed marine community in a single daily flake. Vitamin C at 207mg/kg supports immune function and stress resilience across the tank.

Feed once or twice daily and watch a mixed reef community settle into genuinely consistent, healthy feeding. Fish hold their colour. Activity levels lift. The tank has an energy about it that tells you the nutrition is landing right.

At Reefphyto we have been working with marine fish nutrition since 2008 and Darren is available directly if you want guidance on building a complete feeding programme around your specific community. We understand that every tank is different, and we are here to help you get it right.

A complete marine reef community deserves a complete daily food — give yours the foundation it needs.

For reef keepers running a mixed community tank, the daily feeding routine can quietly become one of the most complicated parts of the hobby. You have fish with different requirements, different feeding behaviours, different positions in the water column. You want them all fed well. You want the water to stay clean. And you want something reliable enough to reach for every single day without second-guessing it.

That is exactly what Marine Flake Premium is designed to be.

What Marine Flake Premium Contains

Marine Flake Premium is a complete daily food for all marine fish, formulated with a composition of fish and fish derivatives, vegetable protein extracts, cereals, yeasts, algae, molluscs and crustaceans, oils and fats, and minerals. At 48% crude protein it sits at the higher end of the marine flake category, with 7% fat providing the energy density active reef fish need to maintain condition throughout the day.

The vitamin profile is the most comprehensive in the Reefphyto core flake range. Vitamin C is included at 207mg/kg four times the level found in the specialist supplement flakes, supporting immune function, wound repair, and stress resilience. The full B-vitamin complex covers B1 (Thiamine), B2 (Riboflavin), B6 (Pyridoxine) and B12 (Cyanocobalamin), alongside Inositol, which plays a role in cell membrane integrity and fat metabolism. Vitamins A, D3 and E complete the additive stack.

Algae is listed in the composition, providing the plant-derived nutrition that omnivorous and herbivore-leaning species need alongside their protein intake. This makes Marine Flake Premium a genuinely broader daily food than a purely carnivore-focused flake.

Analytical breakdown: Crude protein 48%, crude fat 7%, crude fibre 2.4%, crude ash 6.3%.

Which Fish Is Marine Flake Premium For?

Marine Flake Premium is well suited to the kind of mixed reef community most keepers are running: a combination of active mid-water swimmers, smaller reef-safe species, and opportunistic feeders that take whatever arrives at the surface.

It works particularly well for clownfish, chromis, damsels, cardinalfish, small wrasses, gobies, blennies, dottybacks, basslets, anthias, and similar species. Because the composition includes both marine protein and algae, it also covers the nutritional range of omnivorous fish that sit between the purely carnivorous and the purely herbivorous categories.

It is not the primary food for dedicated herbivores such as tangs, rabbitfish, and surgeonfish, which need a higher proportion of plant matter than any protein-forward flake can provide. For those species, Reefphyto Vegetable Flake is the better daily staple, with Marine Flake Premium used alongside it as a complementary protein source.

For fish that are primarily predatory and benefit from a high marine protein or specific ingredient focus, Reefphyto Krill Flake, Brine Shrimp Flake, or Squid Flake offer targeted supplementary feeding two to three times per week. Marine Flake Premium is the everyday foundation those specialist flakes sit alongside.

Complete Food vs Supplement Flake - Why the Distinction Matters

Not all flakes in the Reefphyto range are designed for the same role. Krill Flake, Brine Shrimp Flake, and Squid Flake are specialist supplement foods — formulated around a single high-value marine ingredient and fed two to three times per week to add targeted nutrition on top of a daily staple.

Marine Flake Premium is the daily staple. It is formulated to deliver the full nutritional range a marine fish requires every day: protein, energy, fat-soluble vitamins, water-soluble B-vitamins, trace elements, and plant-based nutrition from algae inclusion. The broader composition reflects a food designed to sustain health long-term, not just deliver a single nutrient hit.

If you are building a feeding routine from scratch, Marine Flake Premium is the logical starting point. The specialist flakes are then rotated in on top of it to add variety and specific nutritional boosts that the daily food does not need to provide alone.

Feeding Marine Flake Premium

Feed small amounts once or twice daily — only as much as the fish will consume within two minutes. Marine Flake Premium is a surface-floating flake. Flakes that sink unfed contribute to nutrient loading and water quality decline, so accurate portion sizing matters. Start conservatively and adjust upward if fish are actively competing for food and clearing the surface quickly.

For tanks running a feeding programme alongside live copepods or other Reefphyto live foods, Marine Flake Premium provides the consistent daily nutritional base while live food delivers the feeding behaviour stimulus and the nutritional complexity that dried food cannot replicate. The two approaches work together rather than competing.

Note: this product contains synthetic colourants E172, E102, E124, E129 and E132.

H2: Frequently Asked Questions

Is Marine Flake Premium suitable as the only food for my marine fish?

It is a complete food, so it covers the core nutritional requirements of marine fish when fed daily. In practice, most experienced reef keepers rotate in additional foods for variety including specialist flakes and live copepods which supports natural feeding behaviour and provides nutritional range beyond what any single food delivers. Marine Flake Premium is an excellent daily foundation; a varied routine builds on top of it.

How does Marine Flake Premium differ from Krill Flake?

Krill Flake is a specialist supplement food built around a minimum 40% krill meal inclusion, delivering natural astaxanthin and the specific fatty acid profile of krill. It is fed two to three times per week for colour enhancement and targeted marine protein. Marine Flake Premium is a broader complete food with a fuller vitamin stack, algae inclusion, and a composition designed for daily feeding across a mixed community. They complement each other rather than overlap.

Can I feed this to marine fish and tropical fish in the same tank?

Marine Flake Premium is formulated specifically for marine fish. For freshwater tropical fish, Reefphyto Tropical Flake Deluxe is the appropriate daily food.

How long does a 45g pot last?

For a small to medium reef tank with a community of six to ten fish, a 45g pot typically lasts three to five weeks when fed once or twice daily in appropriate quantities. The 45g portion size is intentional, it keeps the food fresh and reduces waste compared to larger containers that sit open for months.

Does this food contain live nutrition like your copepods?

No. Marine Flake Premium is a dry food and does not contain live organisms. For live copepods, phytoplankton, and zooplankton, see the Reefphyto live food range. Many keepers use Marine Flake Premium as their daily dry food foundation and add live copepods regularly to provide the feeding stimulus and nutritional complexity that live prey delivers.
