Make hatching fish eggs simple and effective with the BST3D Egg Hatchery. Designed for quick setup in just minutes, this hatchery provides an ideal environment for incubating and hatching fish eggs. The integrated lid design positions your air stone directly above the eggs, creating a gentle circulation of water that flows over the eggs and back to the top of the jar. As the air bubbles rise, they simulate the natural fanning action and water movement that parent fish provide, helping keep eggs oxygenated and healthy throughout development.

The BST3D Egg Hatchery also allows you to hatch eggs outside of the breeding tank, giving you greater control over the incubation process. For breeders who use methylene blue to help prevent fungal growth, the separate hatchery makes it easy to monitor and adjust treatment concentrations without affecting the parent fish or the main aquarium.
