7 things to know before welcoming a Foxface Rabbitfish

Since adults reach 20-25cm, provide a tank with ample swimming space. Adding live rock for hiding spots helps the fish settle in comfortably.

5Intermediate Care Level
While fairly hardy, it requires solid knowledge of water quality management and basic marine fishkeeping, placing it in the intermediate category. First-time marine keepers may want to start with an easier species.
6A Long-Term Commitment
With a lifespan of 5-10 years, keeping this fish is a long-term commitment. It's worth having a sustainable tank maintenance routine in place before bringing one home.
7Preparing the Tank Beforehand
Before introducing the fish, make sure the tank has completed cycling and water parameters are stable. If planning a community tank, it's also worth researching compatibility with existing tankmates in advance.
