Besides adding a dash of color, mystery snails double as efficient tank cleaners, keeping algal growth under control and clearing detritus. Read through for great insights on selecting the best breeder box for mystery snails.

What Is a Breeder Box?

A breeder box is a container designed to temporarily house snail eggs, small offspring, or breeding adults, isolating them from other tank inhabitants. While particularly useful during snail breeding, such as during mystery snail breeding, these boxes also serve as quarantines for unwell aquarium residents until they recover.

Most breeder boxes either float on the water surface or attach to the aquarium wall, allowing them to share the same water with the rest of the tank. They are connected to an air pump to maintain water circulation, preventing stagnation, oxygen deficiency, or contamination.

How Do Mystery Snails Breed?

Mystery snails are gonochoric, meaning each individual is male or female, unlike hermaphroditic species, where an individual can be both.

For breeding to occur, the male mystery snail mounts the female and releases sperm into the female’s gonopore. This leads to internal fertilization, and within a few days, the female lays her eggs in the aquarium.

The yellow or pink eggs look like small spheres enclosed in a sac. For safety, the female snail strategically attaches the egg sac to a sturdy surface such as glass, plant leaves, or gravel.

Unfortunately, this does not prevent other tank residents from preying on these eggs, which are set to hatch in about 3-4 weeks. Upon hatching, the tiny baby snails become easy prey for other tank inhabitants, including larger mystery snails.

In communal tanks, many newborns do not survive their first week, underscoring the need for a safer breeding environment. This is where breeder boxes step in as the ideal solution.

Available in various sizes and shapes, choosing the right breeder box for your mystery snails might seem challenging. However, the guide provided below should facilitate this decision-making process.
