The royal gramma (Gramma Loreto) along with 4 others, the flame angel (Centropyge oriculus), yellow tang (Zebrasome Flavescens), blue tang (Paracanthurus Hepatus) and the percula clownfish (both ocellaris and percula) are the most recognizable fishes in the hobby. It is commonly called the fairy basslet as well.

The royal gramma is a beauty. It is blueish-purple from the front as it fades into a bright orange/yellow towards the back half. It has a thin dark stripe that runs from its snout through its eyes.Also present is a black spot on its dorsal fin.

Royal gramma’s are found around the Caribbean Sea where they are quite common. They go for as little as $15 USD, are disease resistant and hardy. A winning combination. Always available, cheap, beautiful and easily kept in a home aquarium. They are commonly mistaken for the bicolor dottyback (Pseudochromis Bicolor) as they both have very similar colors. Telling them apart is easy. The bicolor dottyback does not have a black streak running from its snout through its eyes.

The royal gramma is a good candidate for a wide variety of aquariums. They are a relatively peaceful fish, provided they have a small territory of their own. I have personally kept the royal gramma with clownfish, dwarf angels, large angels, gobies, damsels and dottybacks and have found that it does well with all of them. Again, only if they have their own territory. There can be trouble if any fish continually attempts to enter its shelter.

Royal grammas can reach lengths of nearly 4 inches in the wild. In captivity however, they usually reach a maximum of 3 inches. Royal grammas have been successfully kept in aquariums as small as 10 gallons. Minimum tank size should be at least 20 gallons since they will eventually attain a length of 3 inches.

Royal grammas are carnivores that eat copepods and plankton in the wild. Your corals are safe with them as they are reef safe. Offer them a variety of meaty foods. Frozen foods such as Krill, Mysis shrimp and Prime Reef (A good blend of raw seafood) are all great choices. They normally begin eating very quickly after introduction.

Efforts to breed the royal gramma have been successful. They are a nest building fish, utilizing macroalgae as for their spawning site (usually a cave). The male tries to lure the female into its newly built spawning site by quivering and flaring its fins. Assuming the female is receptive, they will begin mating in the males cave. Their larvae accept rotifers and eventually baby brine shrimp without hesitation.
