Frequently Asked Questions

Q: What types of fish is this 50mm incubator compatible with?

A: This fish egg incubator is designed primarily for cichlids and other mouthbrooding fish species. It works well with tumbler-style hatcheries used for African and South American cichlids, Discus, and similar egg-laying freshwater fish.

Q: Does this incubator require a battery or electricity?

A: No battery or direct electricity is required. This incubator is driven by your existing aquarium air pump or airstone, which provides the water flow needed to gently tumble and oxygenate the eggs during incubation.

Q: How do I set up the cichlid egg incubator in my tank?

A: Simply connect the incubator to your aquarium air pump using standard airline tubing. Place it in your tank at the desired depth, add the eggs, and adjust air flow so the eggs gently tumble. Ensure your water parameters are stable for the best hatch rates.

Q: Can this incubator help improve fish egg hatch rates?

A: Yes! By continuously tumbling the eggs, the incubator keeps them oxygenated and prevents fungal buildup, which are the two most common causes of egg loss. Many aquarists report significantly higher hatch rates when using a dedicated egg tumbler incubator versus leaving eggs with the parent fish.
