Marine fish pellets, flakes and dried foods

Browse New Life Spectrum Marine Fish Regular 1–1.5mm sinking pellets, Vitalis Marine and Algae formulas, Dymax Marine Complete and Marine Superior pellets, Tropical Bionautic foods and Sera Marine Granules. The range also includes Ocean Nutrition Brine Shrimp Plus Flakes and selected Aqua Natural freeze-dried foods. Match the formula and food size to your fish's diet and feeding habits.

Seaweed for grazing fish

Ocean Nutrition offers green, red and brown marine algae seaweed listings, while Julian Sprung's SeaVeggies includes green, purple and red options. Compare pack sizes and whether a clip is included. Separate seaweed clips, VeggieMag and MegaVeggieMag holders provide additional feeding arrangements; check the selected accessory's mounting and glass-thickness requirements.

Coral and invertebrate foods

Polyp Lab Reef Roids is listed in 37g, 75g and 150g packs. Other options include Seachem Reef Phytoplankton and Reef Zooplankton, Continuum Phyto Blast and Zoo Blast, Two Little Fishies MarineSnow, Coral Essentials Coral Power Food and selected Aquaforest foods. These differ in composition, particle size and intended feeding targets. Check the exact formula's suitability for your corals or filter-feeding invertebrates before choosing.

Vitalis Anemone Pellets and New Life Spectrum Invertebrate pellets provide separate feeding formats. AcroPower amino acids and Polyp Booster are also listed, but their roles differ from particulate foods. Follow product-specific dosing instructions rather than treating supplements and foods as interchangeable.

Live copepods and phytoplankton

Little Creatures listings include live copepods and the Hulk Juice and Gold Rush phytoplankton blends. These live-food listings are marked for in-store pickup only. Check availability, storage and use instructions for the selected product. Ocean Nutrition Instant Baby Brine Shrimp is a separate prepared Artemia product, not a live copepod culture.

Choosing and feeding your reef

Compare livestock requirements, food format and the exact product instructions. Check particle-size specifications on current packaging, especially when choosing coral powders. Adjust portions to consumption, avoid overfeeding and monitor aquarium water parameters. Feeding rings and pouch feeders are listed separately from foods; confirm what is included before ordering.
