Acrylic Breeder/Isolation Box — clear, tool-free separation for healthier tanks What this product does and why you need it Creates a secure, separate habitat inside your aquarium to prevent territorial aggression and stress between species. Makes breeding, treatment, and rearing easier by isolating individual fish without removing them from the main tank. Maintains visibility with high‑transparency acrylic so you can monitor behavior and health without obstruction. Key benefits Reduce aggression and injury: solid internal partitions keep incompatible fish apart while preserving natural tank visibility. Simplify care and feeding: designed access and independent compartments let you feed, medicate, or observe fish with minimal disturbance to the rest of the tank. Promote healthy development: evenly spaced water-flow holes provide steady exchange and a cleaner environment, supporting robust growth of fry and recovering fish. Fast, reliable installation: suction-cup fixation secures the box in place in most aquaria; no tools required and the lightweight construction allows easy repositioning. Main features Material: high-transparency acrylic for clarity and durable separation. Structure: solid divider design integrates into the aquarium without blocking sightlines. Water management: consistent hole placement ensures steady water flow between tank and box. Isolation: internal dividers allow independent sections for separate fish or stages (pregnancy, recovery, fry rearing). Mounting: suction cups hold the unit stable on glass or acrylic tanks—tool-free setup. Practical use scenarios 1) Breeding and fry protection: keep pregnant females and newly hatched fry in a protected compartment with steady water flow and easy feeding access. 2) Quarantine and treatment: isolate sick or medicated fish to prevent cross-contamination while preserving tank circulation for water quality. 3) Temporary separation: separate aggressive individuals or introduce new fish without removing them from the tank, reducing stress and handling risk. Compatibility and performance Designed to work in most aquariums using suction-cup mounting; clear acrylic maintains observation quality. Lightweight and easy to reposition to match changing tank needs or fish life stages. Care and maintenance Rinse with aquarium-safe water; avoid harsh chemicals to preserve clarity. Routine checks of suction cups and holes keep water flow and placement reliable. A practical, transparent solution for breeders, hobbyists, and aquarists who need safe isolation, easy feeding, and steady water flow without removing fish from the main tank.
