- Secure and practical fastening: Suction cups attach the breeding box stably in most aquariums with tool-free, quick setup. The lightweight design simplifies relocation and daily use. - Balanced ecosystem: Evenly spaced perforations promote uniform water flow, supporting a stable micro-environment and healthier inhabitants inside and around the box. - Versatility and compatibility: Ideal for guppy breeding, betta separation, and turtle isolation; integrates smoothly with most community tanks and routine care. - Targeted care: Partition walls enable true isolation for individuals needing special attention, with simple feeding and ongoing aquarium maintenance. - Use scenarios: • Quarantine a new betta or separate aggressive fish without disturbing the rest of the tank. • Raise guppy fry in a controlled section with targeted feeding and reduced predation risk. • Isolate a stressed or injured turtle to promote recovery while maintaining overall tank stability. - Material and size: Made from durable, aquarium-safe materials. Compact footprint fits smaller setups and preserves viewing clarity. - Performance: Reliable suction, stable positioning, and low-maintenance operation.
