Isolation/Breeding Box, Protection and Observation in Aquarium

The isolation or breeding box is an accessory used to temporarily isolate a fish, an invertebrate, or fry without removing them from the main aquarium. It helps protect a weakened individual, prevents aggression among peers, or secures reproduction, all while maintaining the same water parameters.

Historically, the first breeding boxes were simple floating containers or handmade partitions. With the evolution of aquaristics, specific models have been developed, incorporating perforated or meshed walls to ensure good water circulation and constant oxygenation.

Today, modern isolation boxes offer easy setup, good visibility for observation, and increased safety for the animals. They provide a practical solution for the temporary management of fish in reef or marine aquariums.
