Royal Gramma

A peaceful, reef-safe Caribbean basslet with a stunning purple-yellow split body, perfect for beginner reefs.

The Royal Gramma (Gramma loreto) is one of the most beginner-friendly saltwater fish: hardy, peaceful, reef-safe, and visually spectacular with its sharp purple-to-yellow color split.

Care requirements

  • Min tank: 30 gallons
  • Diet: Carnivore — mysis, brine, pellets

  • Reef safe: Yes

Notes

Royal grammas claim a single cave and rarely leave it. Provide rockwork with overhangs and they will thrive for 5–7 years.
