Automatic Feeders
Automatic aquarium feeders ensure regular meals even when you're away: they dispense precise portions of dry food (pellets, granules, flakes) with daily and weekly schedules, reducing waste and nutrient spikes.

How they work: a drum or screw (spiral) releases a set dose at programmed times. Advanced models offer multiple meals per day, fine-tuning of portion size, feeding pause, and app/Wi-Fi control.
Food compatibility: granules/pellets (0.5–2 mm) flow more uniformly; flakes can clump: prefer small doses and a feeding ring to prevent food from ending up in the filter.
Anti-humidity: a sealing lid, desiccant packet, and positioning away from strong evaporation (splashes/sump) keep the food dry and the portion consistent. Some models have integrated ventilation to help keep the food dry.
Power & mounting: batteries (AA/AAA) or USB with a clip on the tank edge or a bracket on the lid. Check tank capacity, number of programmable meals, noise level, and freshwater/marine compatibility.
Best practices: test the feeder 7–10 days before you leave, do not fill beyond 70%, use portions that fish consume in 1–2 minutes, and periodically clean the drum.
Tip: combine fine granules and a feeding ring to concentrate food on the surface and precisely calibrate portions; in reef tanks, set micro-meals to avoid stressing the skimmer.
