- Tool-free installation: suction cups secure attachment to most aquariums. Lightweight design makes it easy to handle and install. - Balanced water flow: evenly spaced perforations promote uniform water circulation, helping maintain a stable environment for fish and other inhabitants. - Flexible isolation: ideal for guppy breeding, betta isolation, and turtle separation; also suitable for isolating sick or pregnant fish and for easier feeding. - Upgraded isolation: compartmentalized divider creates independent spaces, reduces stress, simplifies feeding, and supports daily care. - Durable and safe: aquarium-safe materials designed for reliable performance in real tanks. - Size and compatibility: designed to fit most standard tanks and to integrate with existing setups. - Practical use scenarios: - Breeding: separate fry from adults while preserving water flow. - Recovery and care: isolate sick or pregnant fish for targeted feeding and reduced aggression. - Species management: keep tank mates apart during feeding or recovery.
