Tank Setup
Royal Grammas do best in a stable saltwater aquarium with plenty of live rock, caves, and hiding areas. They often choose a cave or crevice as their territory and may swim upside down or sideways near rockwork, which is normal behavior for this species.
A secure aquarium lid is recommended, as Royal Grammas may jump when startled. They appreciate peaceful tank mates, stable salinity, and good water quality.

Royal Grammas are carnivores and should be fed a varied marine diet. They usually accept prepared foods well once settled into the aquarium.
- Frozen mysis shrimp

- Small marine pellets
- High-quality marine flakes
- Plankton-based frozen foods
Feed small portions once or twice daily and avoid overfeeding to help maintain clean water.
