Lightweight and compact design floats steadily on the water, maximizing oxygen flow and gentle circulation around eggs to boost hatch rates and support healthy fry development. Compatible with a wide range of freshwater species, including tropical fish, snails, amphibians, and turtles, making it a versatile breeding accessory that improves breeding success and hatchling survival. Reusable and easy to clean; the durable foam ring is simple to maintain and supports ongoing breeding cycles in home aquariums and dedicated breeding tanks. Foam ring construction provides a gentle, floating surface that keeps eggs secure while reducing the risk of loss or predation. Use scenarios: In a dedicated breeding tank, it provides a safe egglaying surface for species such as gouramis and small cichlids. In nursery or quarantine tanks, it protects developing eggs and early fry until they are ready to join the main system. In multitank setups, it standardizes egg placement and simplifies maintenance across species.
