The Royal Gramma, also known as the Fairy Basslet, is a vibrant, brightly colored saltwater fish.

This fish is small, peaceful, and easy to care for, making it a popular choice for beginner and experienced aquarists alike.

Reef Safe?

Yes, Royal Grammas are considered reef safe and are unlikely to cause damage to coral or other invertebrates in a reef aquarium.

Environment

Royal Grammas are native to the Caribbean and are used to warm waters. They prefer plenty of hiding spots in the tank, especially caves and crevices. They can tolerate a range of lighting conditions, but may prefer areas of the tank that are not too brightly lit.

Behavior

Royal Grammas are usually peaceful fish that can get along well in a community tank. However, they are territorial and may show aggression towards other Grammas or similar species. They are known to be cave dwellers and will often claim a cave or crevice, which they will defend.

What You Feed: Tropical Blend Flake food, Frozen Marine Blend.

I love this fish, one of my favorites. He hides pretty often if you move too fast by the tank. He’s not aggressive unless other fish go near the cave he’s claimed. This fish has a good little personality and adds a ton of color to the tank. I’d definitely buy again given the chance.

What You Feed: Eats anything

My first saltwater fish and the reason I got into the hobby. Beautiful coloration and fairly peaceful. Will sometimes shake his head or yawn at fish who get too close to “his” cave but has never gone after anything, even fish he probably could eat if he had the attitude. Lives in and around the rockwork, comes out for feeding time. Usually sticks his head out of whatever cave he is hiding in. Has funny habit of orienting himself to the back wall of the tank, so I often find him “sideways”. Can jump if startled. Pros: very colorful, easy to keep Cons: hides a lot, some individuals can be territorial Availability: easy to find

What You Feed: Anything Frozen

Territorial with hiding spots. Wants all of them. Is all bark no bite runs around “yelling” at other inhabitants trying to scare them off. Made a firefish mad once trying to steal the firefish’s hole so got the crap beat out of him. Fins recovered nicely and hasn’t been a bully since. Hides often. Easy to care for.

What You Feed: Pellets, flakes, mysis erc

I have one and it’s really aggressive to all my smaller fish. He is always hiding and it’s hard to feed him. Really nice colors but would never get again. If I would get one I would get a smaller tank for it.

Been a model citizen fish. Noticed it was a little aggressive towards new additions but nothing crazy and everyone gets along now. Good beginner fish and adds a nice pop of color.

Some people have issues with royal grammas being aggressive but mine is always hanging out with my clownfish. The royal gramma is always visible during the day but hides at night.
