A double-compartment fish tank isolation box, specially designed for precision aquaculture, features an innovative fully open side design—the side door can be fully opened or completely removed—paired with a honeycomb‑perforated top cover. This solution effectively addresses the common pain points of “difficult fish handling during insertion and removal, poor water circulation, and suboptimal space utilization.” The isolation box itself boasts a two‑compartment independent design (left and right sections, with customizable dimensions), compatible with fish tank glass up to 15mm thick. It is securely fastened using a combination of clips and non‑slip silicone pads, ensuring stable placement without scratching the glass.

• Full‑open Side Door: The side door employs a “clip‑and‑magnetic” (or all‑clip) mechanism, allowing it to be fully opened or detached for quick and effortless insertion or removal of fish, aquatic plants, or breeding substrates—no need to disassemble the entire isolation box.
• Honeycomb‑Perforated Top Cover: The top cover features a honeycomb grid structure with a porosity of ≥70%, which ensures efficient water circulation while preventing juvenile or small fish from escaping. The top cover is also designed to be easily removable for convenient cleaning or feeding.
• Two Independent Compartments: The left and right compartments can each be used to isolate fish with different behavioral needs—for example, guppy fry paired with betta fish, or broodstock breeding alongside sick fish undergoing treatment—minimizing inter‑species conflicts and boosting overall aquaculture efficiency.
• User‑Friendly Design: Rounded edge chamfers prevent finger injuries, while non‑slip silicone pads on the base protect the glass. The lightweight, streamlined design (approx. 80g) ensures minimal impact on aquarium water quality and flow.

Design Highlights

• Full‑Open Side Door: Fish and items can be inserted or retrieved with “zero obstruction,” eliminating the frustration of traditional isolation boxes that often feature “difficult flip‑lids” or “fish getting stuck” during use.
• Honeycomb‑Perforated Top Cover: Balancing circulation and escape prevention, the top cover is removable for even more convenient cleaning and feeding.
• Two Independent Compartments: One box serves dual purposes, seamlessly accommodating diverse scenarios such as “breeding and isolation” or “sick fish versus healthy fish.”
• Precise Glass Compatibility: With its clip‑and‑non‑slip pad design, the isolation box is compatible with glass up to 15mm thick—and can be installed tool‑free, locking securely in place with just a single click.
• Customization Options: The 3D‑printed model supports adjustments to color, compartment size, side door opening mechanisms, and honeycomb pore diameter, making it ideal for a variety of aquarium sizes—including 40cm and 60cm tanks.

Technical Specifications

• Compatible Glass Thickness: ≤15mm (customizable for 10mm and 12mm)
• Number of Compartments: 2 (independent spaces; default dimensions: left compartment 15cm × 10cm × 8cm, right compartment 15cm × 10cm × 8cm—adjustable based on user needs)
• Recommended Materials: PETG (water‑resistant and corrosion‑proof, perfect for aquatic environments), PLA (eco‑friendly and easy to print, though waterproofing treatment is recommended)
• Printing Recommendations: Use a 0.2mm nozzle, maintain a 30%–40% infill rate to enhance structural strength; ensure the side door clips and top cover mesh walls are at least 1.2mm thick to prevent breakage, and reinforce the clip areas with a higher infill rate of 40%–50%.
• Dimension Reference: Approx. 32cm × 12cm × 9cm (fits most standard 40–60cm medium‑to‑small aquariums; total double‑compartment dimensions are customizable)

Application Scenarios

▸ Breeding and Isolation: Place broodstock and fry in separate compartments; the fully open side door allows for easy observation and transfer, while the breathable top cover helps ensure high survival rates for fry.

▸ Sick Fish Treatment: Use one compartment for sick fish and another for healthy fish to prevent cross‑infection; the side door makes medication administration and water changes quick and hassle‑free.

▸ Transition Period for Mixed Stocking: Before introducing new fish into the main tank, isolate them in separate compartments—allowing them to acclimate gradually; the fully open side door facilitates close monitoring of their condition, while the top cover keeps them safely contained.

▸ Aquatic Plant and Shrimp Farming: Cultivate different types of aquatic plants or ornamental shrimp in the two compartments; the side door simplifies maintenance, while the breathable top cover helps preserve the health and vitality of your aquatic inhabitants.
