San Francisco Bay Brand Frozen Rotifers Mini-Cubes offer an excellent, all-natural micro-food source specifically harvested for filter-feeding marine invertebrates, hard and soft corals, and newly hatched fish larvae or fry. Rotifers (Brachionus plicatilis) are tiny zooplankton that serve as the foundation of the marine food chain. Because of their microscopic size, soft body walls, and slow, drifting motion in the water column, they are easily captured and digested by delicate reef organisms and tiny fish that cannot consume larger frozen foods. This 1.75 oz tray features smaller "mini-cubes" designed specifically to prevent overfeeding in desktop, nano, and small breeding aquariums.
Key benefits
Microscopic Particle Size: Perfectly sized zooplankton (ranging from 100 to 300 microns) that can be easily captured by filter-feeding invertebrates and small-polyp stony (SPS) corals.
Excellent Fry Starter Food: An essential starter food for professional and hobbyist breeders raising newly hatched freshwater or saltwater fish fry and reef larvae.
Highly Digestible Nutrition: Naturally thin, soft cell walls make rotifers incredibly easy for undeveloped digestive tracts to break down, minimizing bloat and digestive issues.
Clean and Pathogen-Free: Provides the exact same feeding response and nutritional profile as live rotifers, but without any risk of introducing harmful aquarium parasites or bacteria.
Ideal for Nano Aquariums: The specialized 36-count mini-cube format delivers tiny, controlled portions that make feeding nano tanks completely hassle-free with zero wasted food.
Specifications
Net weight: 1.75 oz (50 g)
Form: Frozen pop-out mini-cubes (36 cubes)
Primary purpose: Direct feeding for corals, filter feeders, and early-stage fish fry
Water type: Saltwater / Reef and Freshwater (for fry raising)
Target Species: SPS/LPS corals, anemones, feather dusters, clams, tunicates, and newly hatched fish larvae (clownfish, seahorses, tetras).
Suggested use
Feeding frequency: Feed twice daily or as needed for larval development. For mixed reef tanks, feed 2 to 3 times per week.
Portion control: Only feed what your reef inhabitants or fry can consume within 3 minutes. Remove any excess food to maintain clean water.
Feeding method: No rinsing or thawing is required. To target-feed corals, you can thaw a single mini-cube in a small cup of aquarium water and use a syringe or pipette to gently broadcast the mixture directly over the coral polyps. For fish fry, drop the thawed liquid directly into the rearing tank.
Important: Keep frozen until ready to use. Never use a microwave or hot water to thaw frozen fish food, as high heat quickly destroys delicate vitamins and lipids.
Ingredients
Rotifers, water, guar gum.
Guaranteed analysis
Crude Protein (min): 1.9%
Crude Fat (min): 0.4%
Crude Fiber (max): 0.5%
Moisture (max): 96.5%
Ash (max): 0.8%
Phosphorus (min): 0.1%
Storage and safety
Store continuously frozen in your home freezer at 0°F (-18°C) or below.
Do not allow the product to thaw completely and refreeze, as this ruins the physical structure of the rotifers.
Wash hands thoroughly with soap and water after handling frozen aquatic food.
Keep out of reach of children and household pets.
Warnings
For aquarium use only. Not for human consumption.
What’s included
1 x Package of San Francisco Bay Brand Frozen Rotifers (1.75 oz / 36 Mini-Cubes)
Why choose
San Francisco Bay Brand Frozen Rotifers Mini-Cubes offer the simplest way to successfully feed microscopic reef life and fragile fish larvae. By providing clean, flash-frozen marine zooplankton directly in pre-proportioned mini-cubes, this diet eliminates the constant effort and space required to maintain active live cultures. The convenient 1.75 oz blister tray delivers a reliable, nutritious, and pathogen-free solution that ensures high survival rates for newborn fry and robust polyp expansion for your corals without the risk of overfeeding smaller aquatic setups.
