Product features and benefits Clear, durable acrylic construction Made from highly transparent, impact-resistant acrylic so you can monitor isolated fish without visual obstruction. Keeps small or vulnerable fish visible while preventing attacks from larger tankmates. Secure, tool-free installation Assembles quickly without tools and mounts with strong suction cups for stable positioning anywhere in the aquarium. Designed for easy repositioning or removal for cleaning and maintenance. Independent isolation with divider design Internal dividers create separate compartments for individual or grouped isolation. Ideal for isolating sick, injured, pregnant fish, or separating fry while still allowing targeted feeding and observation. Optimized water flow for health and development Evenly spaced holes allow gentle, continuous water circulation through the box. Maintains water quality and natural conditions to support respiration, waste removal, and healthy development. Practical, space-conscious fit Low-profile design integrates into most aquarium layouts without obstructing the overall appearance. Provides maximum safety while fitting seamlessly into existing setups. How this product solves common problems Prevents predation and stress: isolates vulnerable fish from larger, aggressive tankmates while maintaining visual contact and water movement so isolated fish remain healthy and stress is minimized. Simplifies care and feeding: separate compartments let you feed and treat individual fish without disturbing the entire aquarium, making treatments and targeted feeding straightforward. Supports recovery and breeding: continuous water flow and a protective enclosure create a controlled environment for healing or fry development. Typical use scenarios Breeding: Place pregnant females or newly hatched fry in the box to protect them from adult fish and to provide stable, gently circulating water for healthy development. Quarantine and recovery: Isolate sick or injured fish for treatment and observation while keeping them in the same water conditions as the main tank. Aggression control: Temporarily separate aggressive individuals during acclimation or while resolving compatibility issues without removing decorations or rearranging the tank.
