Fish Tank Breeder Net Mesh Box for Fry Separation - 2 Pack

Our review of the 2 Pieces Fish Tank Breeder Net Mesh Breeder Box finds it best for hobby aquarists who need a simple, low-cost way to protect fry, injured, or timid fish inside an existing aquarium. The biggest reason to buy is straightforward: the pair of lightweight polyester mesh boxes creates isolated spaces that keep small fish safe while allowing water to flow through, which helps maintain similar tank water quality without adding a separate breeding tank.

Key Features

• Soft polyester net: A see-through, gentle mesh keeps newborn fry and small fish contained while reducing stress from handling.
• Plastic frame: A lightweight but durable frame makes the breeder boxes easy to lift and reposition without disturbing the tank.
• Suction cup mount: Included suction cups let the box attach to the aquarium wall so it stays in place near the top where visibility and access are best.
• Small holes design: Relatively small side and bottom holes minimize the chance of tiny fish escaping while still allowing water exchange.
• Large internal volume: At about 10.3 x 5.9 x 5.9 in each, the boxes can hold multiple fry or an injured fish while preserving water flow from the main tank.

Who It's For

The breeder net is ideal for home aquarists breeding small tropical fish or keeping injured or bullied fish separate without buying a dedicated breeder tank. It suits people who want a simple in-tank incubator that is easy to install and move and who appreciate being able to watch fry develop in the same aquarium.

It is less appropriate for very large or highly active aggressive species that could damage the plastic frame, or for setups where extremely strong attachment is required; some users report suction cups losing grip. If you need a heavy-duty, permanent isolation tank, a standalone breeder tank may be a better choice.

Pros & Cons

Pros

• Provides a safe, visible isolation area for fry and injured fish without removing them from the main aquarium.
• Lightweight construction and soft mesh make handling and repositioning straightforward and low-stress for fish.
• Design allows water to flow through so conditions inside remain similar to the main tank.

Cons

• Suction cups can be unreliable for some tanks and setups, occasionally causing the box to slip or float if not firmly attached.

Specifications

The Shappy 2-pack breeder net is a practical, budget-friendly solution for home breeders who need temporary isolation for fry or vulnerable fish; it preserves tank water quality while keeping fish visible and protected. It represents good value if you accept a lightweight plastic build and take care to secure the suction cups properly.
