Flexible modular splicing design - Combined splicing design that is flexible and convenient. Fully join and expand the divider to match the width of your aquarium by adding or removing panels. Thick, durable isolation mesh - Multi-functional isolation mesh with a filter mesh design. Thick material provides durability and helps it stay in place, not easy to detach. Professional aquarium divider - Helps isolate different fishes within the same tank, reducing aggression and stress and allowing safe coexistence. Versatile blocking capability - Can be spliced to block filter materials or to form barriers where needed during maintenance or configuration of the tank. Color options - Available in two colors to suit different tank aesthetics and preferences. Size and compatibility - Length and fit can be adjusted by adding or removing panels to suit a range of aquarium widths. Use scenarios - Scenario 1: In a community tank with aggressive or territorial species, use the divider to separate incompatible fish and prevent fighting, while still allowing visual contact. - Scenario 2: Quarantine new fish before introducing them to the main tank. Create a safe isolation area to observe health and acclimation. - Scenario 3: Create a controlled feeding or breeding zone, or temporarily block access to certain areas of the tank during maintenance without full tank disruption.
