Species group: Dottybacks and Pseuedochromis
Other common names:
Scientific name: Pseudochromis fridmani x sankeyi
The Indigo Dottyback was created by crossing the Orchid Dottyback (Pseudochromis fridmani) and the Striped Dottyback (Pseudochromis sankeyi). One of the few marine hybrids available, breeders find it an interesting species to work with.
Appearance / health:
The 7.6 cm (3 in) body is clad in a shade of indigo blue that is rarely if ever exhibited by other fish. A dark stripe runs along the back and the lower edge of the body.
Indigo Dottybacks prove quite hardy when provided proper care. They will not thrive in bare aquariums, being subject to stress-related diseases if not provided with numerous rock and coral caves.
Behavior / temperament:
Indigo Dottybacks are very active, darting in and out of rock and coral caves in the tank’s lower and middle levels. They get along well with many reef fishes and invertebrates, but may harass others of their kind or fish of similar size and body-shape.
The Indigo Dottyback requires a well-filtered and cycled aquarium that is provisioned with numerous rock/coral caves to serve as retreats. Live sand and live rock, which will provide additional food in the form of bristleworms and other tiny invertebrates, should be utilized if possible. They are best housed singly in all but large aquariums.
The following water quality parameters should be maintained in order to assure long-term health: Temperature: 22-25.5 C (72-78 F); Specific Gravity (Salinity): 1.020-1.025; pH: 8.1-8.4.
The diet should include finely-chopped squid, prawn, and other meaty foods, live and frozen rotifers, cyclops, Mysis and brine shrimp, and flakes/pellets formulated for carnivorous marine fishes.
Several Dottyback species have been captive bred. They are hermaphroditic, with any individual being able to function as either male or female. The eggs are deposited inside a rock or coral cave, after which the male chases off the female and then aerates – and sometimes relocates – the eggs. The tiny fry may be reared on brine shrimp naupli and rotifers; plankton preparations are also worth trying.
