Live Rotifers for Reef Aquariums, Daily-Harvested Coral and Newly Hatched Fish Feed in Four Sizes

Give corals and newly hatched fish a live food that encourages a strong feeding response while fitting naturally into your reef-care routine. These live marine rotifers are harvested daily, packed the same day, and never diluted down.

The rotifers come in clean, sterilized Instant Ocean water. Unlike feeds that add unwanted nutrients, they support feeding without adding nitrates or phosphates to the water column. Choose from four bottle sizes to suit your aquarium volume and feeding schedule.

Key Features

• Daily harvesting and same-day packing provide a freshly prepared live food for your reef aquarium.
• The culture is never diluted down, so each bottle contains the stated dense supply of live rotifers rather than a watered-down mixture.
• Live rotifers encourage an active feeding response without adding nitrates or phosphates, supporting thoughtful water-quality management.
• A light shone into the bottle makes the tiny rotifers easier to see, giving you a simple way to check their density before feeding.
• Regular feedings are consumed quickly and may increase mysid shrimp populations, adding useful live prey to the aquarium.
• Feeding the culture live phytoplankton mix keeps the rotifers nutrient-rich for corals and newly hatched fish.

Specifications

• Available sizes: 16 ounce, 32 ounce, 64 ounce, and 1 gallon.
