Introduction
The Electric Blue Jack Dempsey (Rocio octofasciata cf) is a mesmerizing colour morph of the Jack Dempsey Central American Cichlid, making it one of the most sought-after freshwater aquarium fish. Its vivid blue colouration sets it apart from its standard-coloured counterparts. Despite its stunning appearance, the Electric Blue Jack Dempsey is relatively small in size compared to its natural variant. Therefore, it requires a spacious aquarium of at least 190 litres, preferably larger. If live plants are a must-have in your aquarium, choose rooted plants that can withstand repositioning or go for thicker-leaved species. These peaceful Cichlids thrive in large aquariums with like-sized, calm tank mates. They are not as aggressive as other Cichlid species and prefer being housed individually or in small groups with only a few other tankmates. However, when breeding, they become fiercely territorial and will defend their nesting sites. To provide these Cichlids with a home, add a cave or a similar structure where they can retreat when threatened. The Electric Blue Jack Dempsey 's stocky body contrasts its brilliant blue colouration with iridescent metallic blue dots and broken lines standing out against the dark brown background. In conclusion, the Electric Blue Jack Dempsey Cichlid is a stunning addition to any aquarium. With its peaceful demeanour and striking colours, it will surely be the centrepiece of your aquatic display.Electric Blue Jack Dempsey Photos
Sexual Dimorphism
Distinguishing between the genders of Electric Blue Jack Dempsey is a relatively straightforward process. Several physical characteristics can differentiate males and females. Notably, males possess a distinctive round black spot at the centre of their bodies and on the base of their tails. They also have elongated and pointed anal and dorsal fins. In contrast, females display fewer dots, shorter, rounded fins, and a more gravid appearance when ready to breed. These gender differences are valuable to fish enthusiasts and breeders, as they provide an effective means of distinguishing between males and females, facilitating their management and reproduction.Quick Facts
