Live Munnid Isopods - Reef Genetics

Marine Munnid Isopods (Munna sp.) are a unique and highly beneficial microcrustacean that serve both as an effective clean-up crew and a natural live food source for reef aquariums. Larger than copepods but smaller than amphipods, these tiny grazers spend their time feeding on biofilms, detritus, uneaten food, diatoms, cyanobacteria, and other organic waste throughout the aquarium.

Their small size makes them an excellent supplemental food source for mandarins, pipefish, anthias, and other zooplankton-feeding fish, while their constant grazing activity helps support a cleaner, healthier reef ecosystem. Once established, Muniid Isopods readily reproduce in most home aquariums, creating a sustainable population that continuously contributes to both nutrient recycling and natural feeding opportunities.

Key Features:

• 24–30 individuals per culture
• Maximum size of approximately 1–2mm
• Larger than copepods, smaller than amphipods
• Consume biofilms, detritus, uneaten food, diatoms, and cyanobacteria
• Excellent live food source for mandarins, anthias, pipefish, and other micro-predators
• Readily reproduce in established reef aquariums
• Supports biodiversity and natural ecosystem function

A great addition for reef keepers looking to increase microfauna diversity while providing a renewable live food source for picky feeders.

Maintain macroalgae to support sustainable populations over time.
