Lee’s Aquarium Divider – 10 Gallon – A mesh screen divider kit to partition a standard 10-gallon aquarium. It allows you to keep incompatible fish apart or create separate environments within one tank (for breeding, quarantine, or differing species). The divider is semi-transparent and perforated to ensure proper water flow and even heat circulation. It’s easy to install with the included side rails and can be trimmed to fit smaller tanks as well.
