The aF4 Automated Frozen Fish Feeder is the first and only fully automated frozen fish food feeder designed specifically for aquariums. It delivers reliability, consistency, and professional-level feeding automation for both marine and freshwater systems. Ideal for daily use or extended absences, the aF4 ensures your livestock are fed on time, every time — even while you're away.

Say goodbye to the need for expensive or unreliable fish-sitters. With an over 50-cube capacity, integrated cooling, and automatic rinsing, the aF4 is a complete frozen food feeding solution.

Great for high-energy reef fish such as Anthias, predator tanks, seahorses, mixed reef tanks, and even freshwater fish and planted tanks!
