Before You Buy: This tumbler requires an air pump (not included). Use fully submerged. Gentle Mouth-Brooding Simulation: Adjustable bubble lift creates a soft tumbling motion that keeps eggs separated, improving oxygen exchange and helping reduce fungus for higher hatch success.
60 mm Chamber with Rounded Base: Arc-shaped bottom minimizes dead spots and abrasion on fragile eggs; clear body lets you monitor flow and development at a glance.
Top Guard & Fine Mesh Screen: Prevents eggs or fry from escaping and keeps curious fish/debris out of the chamber—protecting developing embryos.
Simple Air-Driven Setup: Connect airline and valve to a capable pump, keep the inlet upright, and fully submerge with the cup top below the tank’s waterline for consistent tumbling.
Easy Cleaning, Aquarium-Safe Materials: Tool-free disassembly for quick rinsing in tank water; inert materials are safe for freshwater cichlids (peacocks, haps, mbuna) and other delicate egg batches.
