40mm Cichlid Egg Tumbler Incubator Hatchery for Aquariums
40mm Aquarium Cichlid Egg Tumbler Incubator — Hatchery for Tropical Fish Eggs
Give your cichlid eggs the best possible start with this purpose-built 40mm fish egg tumbler incubator. Designed to replicate the gentle, oxygen-rich tumbling motion that keeps eggs healthy and developing, this hatchery is an ideal alternative to mouth brooding — protecting your precious clutch while keeping stress on the parent fish to a minimum.
Key Features
- Wide-angle air-lift joint (>90°): Greater than the standard 45° found on most market tumblers, allowing smoother, more comfortable water flow so even a small air pump can drive the unit effectively.
- Ultra-transparent thickened acrylic incubator tube: Precision flat-cut edges for a crystal-clear view of your eggs at every stage of development.
- 1mm sieve plate holes: Fine mesh prevents fish eggs from escaping the main hatching chamber — the lower sieve plate is securely bonded to the incubator body for added security.
- Black biochemical filter cotton: High-quality biochemical cotton (not standard black sponge) provides superior biological filtration within the unit.
- Full acrylic bracket: Keeps the tumbler stable and fully visible inside the aquarium.
- Four transparent suction cups: Reliable aquarium-wall mounting — the unit continues to function normally even if one or two cups need replacing.
- AD-grade connecting parts: Durable gas-lift joints for long-lasting performance.

How to Use: Egg Extraction Guide
- Draw a basin of water from the tank using the aquarium's own water.
- Carefully net and remove the female fish.
- Hold the fish gently with her head facing forward — do not pull from the rear.
- Submerge both hands and the fish in the basin of tank water throughout the process.
- Using a fingernail, gently open the fish's lower jaw — take care not to touch the lips.
- Apply gentle downward and forward pressure simultaneously to open the mouth.
- While keeping the mouth open, move the fish against the direction of her head to release the eggs into the water.
- Repeat until all eggs are released. If the fish escapes, retrieve her promptly before she re-ingests the eggs.
- Inspect the fish's mouth to confirm it is clear, then return her to the main tank.
- Transfer the eggs into the incubator tumbler. If fry are already present, use a separate isolation box placed in the tank with adequate water flow and oxygenation.
- For the first day after extraction, use only the original tank water — avoid water changes during this critical period.
Important Notes
- Actual color may vary slightly from product photos due to monitor and lighting differences.
- Please allow ±1–2 cm measuring tolerance due to manual measurement.

Frequently Asked Questions
Q: What size aquarium is the 40mm cichlid egg tumbler incubator suitable for?
A: This 40mm cichlid egg tumbler incubator works in most standard aquariums. It attaches to the tank wall via four suction cups and requires only a small air pump to operate, making it compatible with a wide range of tank sizes typically used for cichlid breeding setups.
Q: Do I need a special air pump to run this fish egg incubator?
A: No special pump is needed. The wide-angle (>90°) air-lift joint design means even a small, standard aquarium air pump can generate sufficient water flow to keep the eggs tumbling properly inside the incubator chamber.
Q: Can this tumbler hatchery be used for other fish species besides cichlids?
A: While designed specifically with cichlid egg incubation in mind, the tumbler hatchery can also be used for other egg-laying tropical fish species that produce eggs of a suitable size relative to the 1mm sieve plate holes.
Q: How do I clean and maintain the cichlid egg tumbler incubator?
A: Rinse all components thoroughly with aquarium-safe water (never tap water with chlorine) between uses. The biochemical cotton filter insert can be gently rinsed in tank water to preserve beneficial bacteria. Inspect suction cups regularly and replace any that lose grip.
