Overview

The Royal Gramma (Gramma loreto) is a Saltwater (Marine) fish growing to about 3 in and living 5+ yrs. It's peaceful (territorial) and best kept on its own. Plan a tank of at least 30 gal. With a typical lifespan of around 5 years, it's a shorter commitment.

Is the Royal Gramma right for you?

A good match if — you can keep water parameters stable.

Think twice if — you're not ready for the cost and complexity of saltwater; you wanted several of the same kind together.

What a Royal Gramma needs from you

The ongoing work is water quality: filtration, regular water changes and stable parameters. As a marine fish, expect a more complex and more expensive saltwater set-up. Keep it singly, or it will fight its own kind. Don't undersize the tank (minimum about 30 gal).
