About this species
Trimma nasa, commonly called the nasal dwarfgoby or nasal pygmy goby, is a species of goby from the Western Pacific. They are small fish, averaging at around 2 cm (0.79 in) in length. They are bright orange and transparent yellow in life, with a white stripe running down from between the eyes to the upper lip and a dark brown spot at the base of the tail fin. They are usually found in large schools in the sloping or vertical drop-offs at coral reef edges.
