Feeding your reef tank is one of the most enjoyable parts of the hobby. Watching your fish dart about at feeding time or seeing corals extend their polyps to catch food never gets old. But it’s about more than just a bit of fun – the food you choose plays a huge role in the health, colour, and growth of your livestock. The right fish and coral food gives your reef everything it needs to flourish.
At iReef, we stock a wide range of foods designed specifically for marine fish and corals. From nutrient-rich flakes and pellets to frozen foods and specialised coral feeds, our selection makes it easy to give your reef the diet it deserves. Whether you’re keeping a small nano tank with a couple of clownfish or a large reef packed with delicate SPS corals, you’ll find food that meets their needs.
Marine animals rely on a balanced diet just like we do. Fish need protein, vitamins, and minerals to stay active, fight off disease, and show their natural colours. Corals need the right blend of nutrients to grow and build their skeletons, as well as amino acids and trace elements to support vibrant pigmentation.
Poor or inconsistent feeding can lead to:
Pale corals that lose colour due to nutrient deficiencies.
Weak fish that are more prone to stress and illness.
Unstable systems where livestock struggles to thrive.
On the flip side, the right food enhances colour, boosts growth, and keeps your reef looking full of life.
A staple for most marine fish, flakes and pellets are easy to use and provide balanced nutrition. Many are enriched with vitamins and colour enhancers to keep your fish looking their best. Pellets sink slowly, making them ideal for bottom dwellers, while flakes are great for surface feeders.
Frozen options like mysis shrimp, brine shrimp, and krill are hugely popular in reef tanks. They’re packed with protein and mimic the natural diet of many marine fish. Frozen foods also help stimulate natural feeding behaviours, making them a favourite for picky eaters.
Corals may get a lot of energy from light, but most species also benefit from direct feeding. Coral foods often come as powders or liquids packed with amino acids, phytoplankton, and zooplankton. These feeds promote growth, improve colouration, and help corals recover after fragging or stress.
Many marine fish, such as tangs and herbivores, need algae in their diet. Sheets of dried seaweed or algae-based pellets provide essential fibre and nutrients. They also keep grazing species happy and healthy, reducing stress and aggression.
From high-protein fry food for young fish to target feeds for LPS corals, specialist foods let you fine-tune your feeding regime to match your livestock’s exact needs.
It’s easy to think of reef feeding as just throwing in some flakes for the fish, but corals need attention too. LPS corals, in particular, benefit from direct feeding with meaty foods, while SPS corals respond well to fine powdered foods and amino acids. Feeding corals regularly encourages better polyp extension, brighter colours, and faster growth.
Fish, on the other hand, should be fed small amounts regularly rather than one big dump of food. This reduces waste and keeps nutrient levels in your tank under control. A varied diet of dry, frozen, and algae-based foods usually works best.
Overfeeding is one of the most common mistakes in reef keeping. Too much food quickly leads to elevated nitrates and phosphates, fuelling algae growth and harming corals. The key is balance – give your fish and corals enough to thrive, but not so much that it overwhelms your system.
Using tools like feeding rings, target feeders, or even automatic feeders can help ensure the right amount is delivered consistently.
At iReef, we only stock reef-safe fish and coral food from brands we know and trust. These foods are formulated specifically for marine tanks, ensuring the right balance of nutrients without unnecessary fillers. That means healthier fish, more vibrant corals, and less waste breaking down in your system.
By choosing trusted food, you’ll not only see a difference in the appearance of your livestock but also in the overall stability of your tank.
We’re passionate reef keepers ourselves, so we know how important feeding is. We’ve chosen a range of foods that are proven to work, with options for every type of tank and every kind of livestock. Whether you’re feeding a pair of clownfish in a nano setup or a full reef full of tangs, wrasses, and SPS corals, we’ve got the right food to keep your reef thriving.
On top of that, we offer competitive prices, fast delivery, and the reassurance that everything we stock is safe for your reef.
A reef tank is a living ecosystem, and just like any other, it depends on good nutrition to thrive.
