Spawning box for free spawners with integrated filtering.

The special feature of this spawning box is the open access to the spawning site. For long-term spawners, the preferred spawning substrate is placed directly on the spawning grid. Once discovered, the same spot is visited again every day to spawn.

Barbs, rasboras and also tetras sometimes have a difficult start in life. Spawning predators, which can even include the parents, ensure that only a fraction of the offspring make it through.

Barbs and rasboras have non-stick spawn. This falls through the spawning substrate (example: Java moss, very popular with guinea fowl danios) to the bottom where it is easy prey for many aquarium inhabitants.

This no longer happens with our spawning grid.

The spawning chamber is equipped with a practical door. Equipped for all breeding projects! Direct mating or spawning quarantine with the door closed. Long-term spawners such as rasboras can come to the spawning area every day with the door open and swim back into the open tank.

But tetras whose spawn is "glued" to fine-feathered leaves also have a much greater chance of growing in peace thanks to the wedge insert.

Immediately after hatching, the young animals seek shelter and follow the current through the narrow slots in the wedge.

The built-in HMF filter ensures a constant supply of fresh, oxygen-rich water. This helps to prevent spawning fungi and supports the existing filtering of the entire tank.


Details such as a hose feedthrough and rounded edges without visually disturbing adhesive spots or bulging silicone joints make the difference.

Our premium box is not only lighter than a glass container, but is also completely scratch-free for the aquarium panes.
