Material integrity: Thermally tempered acrylic glass resists warping and clouding, providing enduring clarity for reliable fish observation and brood care. Practical handling: Removable mesh cover with a stainless steel frame enables optimal water circulation; rounded edges reduce injury risk during breeding. Intuitive operation: Water level adjustment with an adjustable height allows tool-free installation; secure hold through a snap-fit design without complex settings. Conflict minimization: Creates clearly defined territories in the aquarium layout, reduces territorial fights sustainably, and supports healthy fry development. Use scenarios: - Breeding and fry care: Isolate a breeding pair or fry area in a community tank while maintaining visibility and water flow. - Territorial management: Use as a divider in mixed-species tanks to reduce aggression and provide stable zones for different life stages. - Quarantine and observation: Place in a quarantine tank to monitor new arrivals with clear sightlines.
