The royal gramma, Gramma loreto, is a very popular fish in the aquarium trae. The fish begins as a dark purple which fades to yellow. The royal gramma resembles the false gramma (Pseudochromis paccagnellae), with the two main differences between the two being that the false gramma has clear fins and does not fade, but rather has a distinct change in colour. Royal gramma averages slightly over 8 cm (3 inches) and has been tank bred. Their natural range covers the Bahamas, Venezuela, and the Lesser Antilles. They are carnivorous and eat most meat-based diets.
