A fish tank isolation box specially designed for aquarium keeping, crafted from 3D‑printed materials and secured to the aquarium glass using a clip-and‑latch system. It’s perfectly suited for fish tanks with glass thicknesses of 15 mm or less, addressing key challenges such as isolating sick fish, providing a safe environment for breeding and egg hatching, protecting juvenile fish, and facilitating the stable planting of aquatic plants. The isolation box features a square design with a transparent, view‑through construction that remains securely in place without scratching the glass after installation.

• Precise Glass Compatibility: The clip‑and‑latch design accommodates 10 mm, 12 mm, and 15 mm glass panes, enabling tool‑free installation—just snap it into place and it stays firmly secure.
• Multipurpose Functionality: Ideal for isolating sick fish to prevent cross‑infection; providing a dedicated space for breeding and egg hatching by separating mother fish from eggs; safeguarding juvenile fish from being eaten by larger adults; and supporting the stable planting of aquatic plants like mosses and Java ferns.
• Escape‑Proof & Water‑Permeable: The box is equipped with a dense grid or perforated holes (with hole diameters ≤ 2 mm), effectively preventing fish and shrimp from escaping while ensuring adequate water circulation to maintain stable water quality.
• User‑Friendly Design Features: Smooth, rounded edges minimize the risk of injury to fish and shrimp; the transparent material allows for easy observation; and the bottom can be configured as either angled or flat, catering to diverse aquarist needs.

Design Highlights

• Dual Fixation System: Combines mechanical clamping via clips with secondary reinforcement through latches, offering flexible installation options to accommodate various aquarium structures.
• Escape‑Proof & Balanced Water Flow: The grid and perforated hole design not only prevents fish and shrimp from escaping but also ensures continuous water circulation, helping to avoid stagnation and degradation of water quality within the box.
• Precise Glass Adaptability: The clip spacing and latch dimensions are meticulously calibrated to fit glass up to 15 mm thick—guaranteeing a snug, vibration‑free fit that won’t loosen or fall off.
• Customization Options: The 3D‑printed model supports adjustments to shape (square), size (length, width, height), and hole configuration (grid patterns), making it compatible with a wide range of aquarium specifications.

Technical Specifications

• Compatible Glass Thickness: Up to 15 mm (customizable for 8 mm, 10 mm, and 12 mm glass)
• Box Dimensions: Approximately 10 cm × 10 cm × 8 cm (adjustable to meet specific needs; available in mini and large‑capacity versions)
• Recommended Materials: Acrylic (transparent, highly water‑resistant) or PETG (ideal for 3D printing, offering excellent temperature resistance and wear‑proof performance)
• Hole Type/Diameter: Grid holes (2 mm × 2 mm), round holes (2 mm diameter), with a density of ≥ 80 holes per square decimeter (designed to prevent escape).
• Printing Recommendations (for 3D‑printed models): Use a 0.2 mm nozzle, set the infill to 30% for enhanced structural integrity, apply R1 edge chamfers to prevent scratches, and ensure grid hole walls are at least 1 mm thick to resist breakage.

Application Scenarios

▸ Sick Fish Isolation: Isolate ailing ornamental fish to prevent cross‑infection and facilitate targeted treatment.

▸ Breeding and Egg Hatching: Separate mother fish after spawning to protect eggs and fry from being consumed by adult fish.

▸ Juvenile Fish Protection: Newly hatched juveniles are small and vulnerable—isolating them helps shield them from predation by larger fish.

▸ Aquatic Plant Planting: Use the grid to anchor the roots of shade‑loving plants like mosses and Java ferns, while still allowing sufficient light penetration and water flow to support healthy growth.

Real‑World Application Examples (with Images)

• The isolation box is securely fastened to the aquarium glass using a clip‑and‑latch system, with a clear, transparent view of the interior. The internal grid is crisp and well‑defined, offering a clear visual overview of the fish, shrimp, and aquatic plants inside.
• The box features a angled bottom (or a flat bottom, depending on user preference), allowing it to adapt to different aquarist requirements—angled bottoms make it easier for juvenile fish to swim out, while flat bottoms provide a stable surface for planting aquatic plants.
