The Red Tail Dottyback can actually range in color from a golden yellow to orange to red then to black, depending on their location. The lighter variety that are male, are more spectacular because when courting and spawning their thin horizontal lines become bright blue and more visible.
Females have a red oval or circular red color in the middle of their body that runs from in front to just behind the anal fin and from the belly to the upper back, but not to the top of their back. The body is elongated and their tail fin is rounded. The color of the fins are typically the main color of the body. They can reach 7.8” (20 cm) and are mature around 5.8” (14.9 cm). It is unknown how long they live, however other dottybacks have lived at least 10 years in captivity.
All dottybacks share a few traits, which are scales on their heads, their pear shaped black pupil and continuous dorsal fin to name a few. In the wild, dottybacks are quite fearful, however this quickly changes in captive environments.
Dottybacks are born female and change to male as needed, similar to wrasses. They will ambush prey, sitting and waiting for dinner to come to them. If nothing comes around, after 20 to 30 seconds, they will move onto another spot. In the wild, they are low on the food chain, which explains why approaching them is very difficult. In captivity, it is quite different!
