Richardson dragonet is found in sandy areas of shallow waters. Its mouth is located on the bottom, which it stretches to capture creatures on the ocean floor like bristle worms.
You can tell males apart from females by looking at their dorsal fins.
Usually they stay at the bottom of the ocean, but during breeding season, the male approaches the female, puts them on their pectoral fin and ascends. About 2 m above, the female lays her eggs in the open and the male releases his sperm into it. This method is known as external fertilization. You can see this happen in the tank as well.
