Square Acrylic Fish Isolation Box — Aquarium Breeding & Hatchery Key benefits Protects fish from injury and stress: the square isolation design creates a clear physical barrier to separate fry, injured, or aggressive individuals, reducing finnipping and overcrowdingrelated harm. Supports better growth and survival: controlled separation helps young or vulnerable fish feed and develop without competition or harassment. Easy monitoring and care: fully transparent acrylic lets you observe behavior, health, and feeding without disturbing the fish. What it does Functions as an isolation box, breeding/hatchery chamber, and temporary quarantine space. Designed specifically for small aquarium species such as medaka, bettas, and clownfish. Features and materials Square design: stable shape that fits neatly into aquariums while maximizing internal volume for small groups or individual fish. Transparent acrylic construction: clear visibility for inspection and feeding; lightweight for easy handling. Small, lightweight accessory: simple to position inside your tank; no special tools required for setup. How it solves common problems Prevents aggression: separates territorial or aggressive adults from more vulnerable fish. Protects fry: creates a safe area for newly hatched fish to grow without being eaten or outcompeted. Enables quarantine: isolates sick or injured fish for observation and treatment without removing them from the tank environment. Typical use scenarios Breeding: place gravid females or eggs inside the box to protect fry during hatching and early development. Protecting betta or medaka fry: separate fry from adult tankmates until they reach a less vulnerable size. Quarantine/rehab: isolate a wounded or ill fish for observation and targeted care while keeping it in the main aquarium's water. Installation and care Place the box inside your aquarium in a calm area with gentle water flow. Monitor water conditions and clean the box as needed to maintain water quality. Lightweight design makes removal, inspection, and cleaning straightforward. Suitable for aquarium owners who need a simple, transparent isolation and breeding solution for small fish species such as medaka, bettas, and clownfish.
