Crew Quarters

Give new arrivals a safer start with The Crew’s Quarters, a reef tank isolation box designed for new fish, coral frags, and anemones. This corner-mounted isolation system helps protect delicate tank mates while they acclimate, recover, or settle in before joining the main reef.

Built to sit neatly in the corner of your aquarium, The Crew’s Quarters uses the tank glass as part of the enclosure to save space and keep your display looking tidy. The open-flow design allows strong water exchange, helping maintain stable temperature and water chemistry while still keeping your new addition safely separated.

Whether you're introducing a new fish, protecting a coral from curious tank mates, or giving an anemone a secure temporary home, The Crew’s Quarters makes reef tank acclimation simple, safe, and stress-free.

Made from reef-safe PETG and designed for easy placement and cleaning, it’s a practical solution for reef keepers who want a cleaner, smarter way to isolate livestock in the display tank.

Isolation box or quarantine tank?

The Crew's Quarters is an in-display enclosure, so it shares water with the aquarium. It provides physical separation for supervised introductions, observation and suitable temporary recovery situations, but it does not isolate waterborne pathogens and is not a replacement for a separate quarantine tank or disease-treatment protocol.

There is no universal acclimation duration. Monitor the animal's condition, feeding response and interactions with established livestock rather than releasing it after an arbitrary fixed period.
