Oceans Reefs & Aquariums is offering limited availability of its captive bred black margin dottyback (Pseudochromis tapeinosoma), an aggressive member of the Pseudochromis genus, especially with conspecifics, reports ReefBuilders. Male fish sport a yellow body with a navy blue stripe that starts at its nose and ends around the edges of its tail.
The black margin dottyback is known to flash their colors at the presence of potential mates or competitors. Females are gray with a yellow tail. They are known as protogynous hermaphrodites, with males beginning to show their coloration at around 1.5 inches, according to ORA. In order to acquire one of these specimens, you’ll need to find a local fish store that ORA ships their fish to and hope they can get one in for you.
