The best food for corals depends on what the animals can capture and how you manage the aquarium. PolypLab Reef-Roids is our powder option for a mixed reef feeding routine; Reef Nutrition Oyster-Feast offers a documented small-particle range; Fauna Marin LPS Grow + Color provides soft granules for targeted feeding; and Red Sea Reef Energy Plus AB+ supplies dissolved and suspended nutrients in liquid form.
This shortlist compares current manufacturer descriptions, instructions and storage requirements. It is a buying guide based on those documents, without hands-on growth trials, invented rankings or promises that a particular food will improve every coral’s color.
Start with the livestock: identify the corals you keep and their feeding needs before choosing a food. A small-polyp stony coral, a large fleshy polyp and a non-photosynthetic coral do not automatically need the same food or feeding routine. Tank volume alone is not a complete feeding plan.
Four coral foods for different feeding jobs
| Exact product | Format | Useful fit | Main limitation |
|---|---|---|---|
| PolypLab Reef-Roids, 75 g refill pouch | Marine-plankton powder | A dry food option for filter-feeding corals | Requires mixing and a tank-specific feeding plan |
| Reef Nutrition Oyster-Feast, Small 6 oz | Oyster eggs and ovarian tissue; 1–200 microns | Small-particle feeding, including the maker’s SPS and LPS examples | Refrigerate before and after opening |
| Fauna Marin LPS Grow + Color M, 60 g | Soft-based granules | Targeted feeding of suitable larger polyps | Granule acceptance and size must suit the animal |
| Red Sea Reef Energy Plus AB+, 500 ml | Dissolved and suspended nutrients | A liquid nutrition routine with careful monitoring | Refrigerate after opening; dosing-reservoir handling has separate rules |
1. PolypLab Reef-Roids: a powder option for filter-feeding corals
PolypLab describes Reef-Roids as a marine-plankton blend and lists a 75-gram size. Its intended coral examples include Goniopora, zoanthids and mushrooms. The retail option linked here is one 75 g refill pouch, with no jar included.
We would start the comparison here if you prefer a dry food that you mix with aquarium water. The manufacturer’s directions allow targeted feeding or dispersing the mixture in the aquarium. That flexibility is useful, but it does not mean every coral will capture the same amount or that a whole-tank addition is automatically appropriate.
- Pros: dry powder format; a clearly identified 75 g refill; targeted or dispersed feeding options in the maker’s instructions.
- Cons: preparation is required; a refill pouch does not include a jar; the quantity and frequency still need to suit your livestock and nutrient processing.

Compare the manufacturer’s Reef-Roids description with the exact package you buy. Follow a clear current label; if a direction or unit is ambiguous, confirm it with the manufacturer before feeding.
2. Reef Nutrition Oyster-Feast: for a documented small-particle range
Oyster-Feast combines oyster eggs and ovarian tissue. Reef Nutrition specifies particles from 1 to 200 microns and names Acropora and Montipora among its SPS examples, with Goniopora and Favites among its LPS examples. The Small 6 oz bottle is the size compared here.
This is the strongest fit in our list when a documented particle-size range helps you match food to the corals. It also brings a storage commitment: the maker says to refrigerate it at 33–42°F, or 1–5°C, both before and after opening. Check the bottle’s best-by date and storage history when buying.
- Pros: explicit particle-size range; specific coral examples; a small bottle option for comparing with your expected use.
- Cons: refrigeration is essential to the stated storage routine; undiluted target feeding is not advised by the manufacturer; adding more because polyps respond is not a complete nutrient-management plan.
Check Oyster-Feast Small 6 oz and its use-and-storage instructions.
3. Fauna Marin LPS Grow + Color M: for deliberate target feeding
The exact option here is LPS Grow + Color M in the 60 g package. Fauna Marin describes it as a soft-based granular food made with natural marine ingredients, intended for LPS corals and other non-photosynthetic corals. Its directions include soaking the granules in saltwater before placing food at the polyps.
We would compare this with the powders and liquids when the goal is feeding individual polyps that can accept the chosen granule. “LPS” on the label should not replace checking the needs and feeding response of your particular animal. The M size is also part of the product identity, so do not substitute another granule size without checking it.
- Pros: granules support deliberate placement; the maker specifies a soft-based format and a preparation method; the exact M/60 g package is identifiable.
- Cons: more attention to individual animals than a simple whole-tank addition; suitability depends on the polyp and granule size; it is not our default choice for every small-polyp coral.

4. Red Sea Reef Energy Plus AB+: for a managed liquid feeding routine
Reef Energy Plus AB+ contains an organic complex of dissolved and suspended carbohydrates, amino acids, fatty acids and vitamins. The selected bottle is 500 ml. Its liquid nutrient approach differs from feeding a visible granule to an individual polyp.
This is worth comparing when you want a liquid product and can follow a regular monitoring and storage routine. Refrigerate the bottle after opening. For dosing pumps, Red Sea’s manual permits a week’s supply in an unrefrigerated dosing container, with thorough cleaning between refills; that is a separate arrangement from leaving the main bottle out indefinitely.
- Pros: combined nutrient formulation; manual guidance for dosing-pump use; a clearly identified 500 ml bottle.
- Cons: refrigeration and reservoir maintenance need planning; the manual warns that overfeeding can be associated with biofilm and algae; it is not evidence that other husbandry needs disappear.
Read the current Red Sea product information and its feeding and storage manual before choosing the bottle size.
How to choose without overfeeding the aquarium
- Match the format: compare the animal’s feeding needs with the actual particle or nutrient format. Oyster-Feast publishes a numerical particle range; LPS Grow + Color M is a granule; Reef-Roids is a powder; AB+ includes dissolved nutrients. These are different jobs, even when several labels mention the same coral group.
- Consider the whole feeding routine: account for other foods added to the aquarium. Reef Nutrition explains that captive systems process nutrients at different rates. Adding several foods does not make each one’s full feeding recommendation independently suitable for the same tank.
- Watch the corals and water together: Red Sea’s manual advises monitoring coral appearance and changes in nitrate and phosphate. It also notes that apparent feeding problems may have other causes. Avoid treating poor color or a closed polyp as proof that it needs more food.
- Buy a manageable package: choose a size you can store correctly and use within its label guidance. Oyster-Feast needs refrigeration before opening; AB+ needs it after opening. Follow each food’s own instructions instead of treating all liquid coral foods alike.
Frequently asked questions
Is one coral food best for every reef tank?
No single pick earns that claim here. Select by the corals present, food format, feeding method, storage and the aquarium’s nutrient response. A mixed reef may require more than one approach, but that is not a reason to add all four foods automatically.
Can I use the same dose for every product?
No. These products have different forms and manufacturer instructions. Use the current product label as a starting reference for the appropriate animals and system, and monitor the response. This guide intentionally does not provide one dose or schedule for every tank.
Will coral food guarantee faster growth or better color?
We do not make that promise. Food choice is one part of coral care, and Red Sea’s own manual says signs attributed to feeding may have other causes. Compare suitability and handling requirements before treating a manufacturer’s growth or color claim as an expected result.
