The Robustus Butterfly (Chaetodon robustus), also known as the Three-Banded Butterfly, is a beautiful and elusive fish found among the reefs of the Atlantic and Caribbean Ocean. They have a silver or white body with three dark vertical stripes and yellow accents. Reaching a maximum size of 6 inches, they do best in FOWLR tanks with tankmates of similar temperaments.

Reef Safe Status of the Robustus Butterfly

The Robustus Butterfly is generally not considered reef-safe, as it tends to focus on a diet of coral polyps. However, caution is advised when introducing it into a reef tank, as individual preferences may vary. Regular observation and monitoring are crucial to ensure compatibility with coral specimens.

Aquaculture and Availability of the Robustus Butterfly

The Robustus Butterfly is not widely aquacultured, making wild-caught specimens more common in the hobbyist market. It is crucial to source individuals from reputable suppliers to ensure the health and sustainability of the species.

Compatibility with other fish and invertebrates depends on the specific dynamics of the tank, and careful observation is required when introducing new tank mates.
