Product Introduction

This is a 3D-printed isolation device specifically designed for ornamental fish, such as guppies and tropical fish. It features a floating, lid-equipped design that allows it to stably float in the aquarium water without the need for additional fixation. The box is equipped with perforated ventilation holes around its sides and on the top, providing a separate breeding/isolation space for the broodfish while allowing fry to freely move into the outer layer (thus preventing them from being eaten). The top lid offers dust protection and prevents fish and shrimp from jumping out, while also ensuring natural water circulation. The overall design is simple and compact, making it suitable for various small ornamental aquariums; it serves as a practical auxiliary tool for fish breeding and for isolating sick fish.

Design Highlights

1. Floating Design: Thanks to a lightweight structure combined with bottom weighting (or buoyancy design), the device can stably float in the water without requiring glue or supporting brackets, making installation quick and easy.
2. Lid for Dust and Jump Prevention: The included top lid effectively keeps dust and debris from falling in while also preventing fish and shrimp from jumping out of the isolation box.
3. Multihole Breathable Structure: The box body and top are densely perforated, ensuring good water flow and promoting respiration and water exchange for fish and shrimp.
4. One-Piece 3D-Printed Construction: The compact, seamless design features rounded edges with no sharp corners, reducing the risk of injury to fish and shrimp; the perforated and mesh design balances breathability with safety.

Technical Specifications

• Model Format: STL (the standard format for 3D printing)
• Printing Process: FDM (or SLA photopolymerization; PETG or PLA materials are recommended)
• Applicable Aquariums: Small ornamental aquariums (water level ≥15 cm; tank size is flexible as long as it can accommodate the floating box)
• Dimensions (approximate): Length × Width × Height = 6 cm × 6 cm × 4 cm (internal isolation space ≈ 4 cm × 4 cm)
• Printing Accuracy: A layer thickness of 0.1–0.2 mm is recommended to ensure clear hole and structural details
• Assembly Method: The entire unit is printed in one piece, with the lid simply placed on top of the box body

Application Scenarios

• During the breeding season of guppies (or other small ovoviviparous fish), to isolate the broodfish from the fry
• “Temporary quarantine” before introducing new fish into the tank (to monitor their health status)
• Isolation and treatment of sick fish (to prevent cross-infection while maintaining water exchange)
• Display or standby use in an empty tank (can be left in the aquarium at all times without affecting the aquascape)
