Reefphyto Squid Flake
Reefphyto Squid Flake. 46.5% protein mollusc-based supplement flake for carnivorous marine and tropical fish.
Predatory marine fish encounter a wide range of prey in the wild. Alongside the small crustaceans and zooplankton that form the bulk of many reef fish diets, cephalopods, squid and cuttlefish are a significant protein source for larger carnivores, triggering a distinct feeding response that crustacean-based foods don't replicate in the same way. A reef tank fed exclusively on a single staple food will never fully satisfy that predatory range.
Dietary variety in carnivorous fish is not just about palatability. Different protein sources deliver different amino acid profiles, and rotating supplement foods alongside a complete staple gives fish access to a broader nutritional spectrum than any single food can provide. The response to an unfamiliar prey-type food the alertness, the speed of the strike, the completeness of the feed reflects biology working as it should.
Reefphyto Squid Flake is a 45g supplement flake built around squid as the key mollusc protein source, within a composition of fish and fish derivatives, molluscs and crustaceans, derivatives of vegetable origin, cereals, algae, yeasts, and oils and fats. Crude protein is 46.5%, fat 5%, fibre 3%, and ash 6%. This is a supplement food designed to be offered twice per week alongside a complete staple diet, not as a daily replacement. Feed sparingly, offering only what your fish will consume within two minutes on supplement feeding days.
In a reef tank where carnivorous species are fed well and with variety, the difference shows in how they carry themselves. Richer colour, a sharper feeding response, and the settled confidence of an animal whose nutritional needs are genuinely being met rather than approximately managed.
Reefphyto sources, packs, and labels this flake ourselves from a trusted European supplier, so we can stand behind the quality of what reaches you. Darren and the team are available directly at [email protected] or on 01267 611533 if you have questions about building a complete feeding programme for your specific fish.
Give your carnivores something worth hunting, and watch the difference in how they respond.
Marine fish are not opportunistic feeders in the broad sense that phrase sometimes implies. Many are highly specific predators, tuned over evolutionary time to particular prey types, and their feeding behaviour in captivity reflects that specificity whether or not we acknowledge it. A lionfish, a grouper, a hawkfish, a moray — these are animals whose neurological response to different prey shapes how they feed, how actively they hunt, and how well they convert nutrition into condition and colour.
Squid and cuttlefish occupy a significant place in the prey spectrum of many predatory marine fish. Unlike crustaceans, cephalopods offer a different protein profile: high in taurine, rich in the specific amino acids that support muscle condition in fast-moving predatory species, and carrying a scent signature that triggers feeding in fish that might respond only weakly to generic flake. In the wild, larger reef predators encounter squid regularly. In a captive tank fed exclusively on a single staple, that encounter never happens.
Reefphyto Squid Flake is designed to bring that encounter back into the feeding rotation.
What is Reefphyto Squid Flake?
Reefphyto Squid Flake is a 45g supplement flake formulated with squid as the primary mollusc protein component, within a full composition of fish and fish derivatives, molluscs and crustaceans, derivatives of vegetable origin, cereals, algae, yeasts, and oils and fats. The analytical profile is 46.5% crude protein, 5% fat, 3% fibre, and 6% ash a high-protein, low-fat formulation well suited to the metabolic needs of carnivorous marine species.
Reefphyto sources this flake in bulk from a trusted European supplier and packs it under our own label, allowing us to control freshness and quality from the moment it leaves production to the moment it reaches your door. The 45g format is sized for regular supplement use without the deterioration risk of a larger container opened infrequently in a humid fish room environment.
Supplement Food, Not a Staple - The Right Way to Use Squid Flake
This is the same principle that applies across the Reefphyto supplement flake range: Squid Flake is a twice-weekly supplement to be used alongside a complete staple diet, not as a daily replacement for it.
Squid is a nutritionally valuable protein source but does not in isolation provide the full vitamin and mineral spectrum that carnivorous marine fish need for long-term health. Used as directed — twice per week alongside a complete food — it adds genuine prey-type variety and a different amino acid contribution that a single-protein staple cannot replicate. Used as the only food, it will leave nutritional gaps over time.
Which Fish Is This For?
Reefphyto Squid Flake is suited to carnivorous and omnivorous marine and tropical fish. In a reef context it is particularly well suited to hawkfish, dottybacks, larger damselfish, wrasse, anthias, and any species that in the wild hunts actively for invertebrate prey beyond small crustaceans. For larger predatory marines in a fish-only or FOWLR system — lionfish, groupers, moray eels, triggers — squid-based foods are a more natural nutritional match than crustacean or plant-derived flakes.
It is not suited as a primary food for herbivores. Tangs, rabbitfish, and marine angelfish should be fed an algae-dominant food as their staple, such as Reefphyto Premium Soft Algae Pellets.
How Squid Flake Differs from Brine Shrimp Flake
Both products are high-protein Aquadip-sourced supplement flakes at the same price point and in the same 45g format. The distinction is the protein source and the prey type it represents.
Reefphyto Brine Shrimp Flake is built around Artemia a small crustacean that represents the copepod-and-zooplankton prey profile most relevant to reef community fish like clownfish, chromis, damsels, gobies, and blennies. Squid Flake is built around a cephalopod protein source, which represents the larger invertebrate prey profile more relevant to active predators and larger reef carnivores.
For a reef community tank, rotating both on alternate supplement days gives omnivorous and carnivorous species exposure to two distinct protein sources and two distinct feeding stimuli, producing a more complete nutritional rotation than either product alone.
Pairing Squid Flake with Live Marine Nutrition
For reef keepers already using live copepods or zooplankton from Reefphyto, squid flake makes a practical high-protein supplement on non-live-feed days. Live copepods provide the highest-quality hunting stimulus and the most nutritionally complete crustacean prey experience; squid flake adds a different protein dimension on the days between live food additions without the cost or planning of a second live food order.
The most complete carnivore feeding programme combines a quality complete staple, a live crustacean food such as live copepods, and a rotation of supplement flakes including squid. Each element adds something the others cannot replace.
HFeeding Guide
Feed sparingly once or twice on supplement days. Offer only as much as your fish will consume within two minutes. Do not use as a replacement for your complete staple food offer alongside or immediately after the regular feed, or as a separate feeding event at a different time of day. Twice-weekly supplemental feeding is the recommended frequency.
Store in a cool, dry location away from direct light. Close the container promptly after each use.
Frequently Asked Questions
Is this a complete food? No. Reefphyto Squid Flake is a supplement food for use twice weekly alongside a complete staple diet.
Is it reef-safe? Yes, in normal feeding quantities. Feed sparingly and remove any uneaten flake promptly to protect water quality.
How does this differ from Brine Shrimp Flake? The protein source is different — squid rather than Artemia. Brine Shrimp Flake suits reef community fish and omnivores; Squid Flake is particularly well suited to active carnivores and larger predatory marines. Rotating both is the best approach for a mixed carnivore community.
