Electric Blue Jack Dempsey native habitat, distribution, behavior & aquarium compatibility.
Nandopsis octofasciatum, commonly known as the Jack Dempsey, also has a less common, natural variant which is specifically known as the Electric Blue Jack Dempsey. The Electric Blue Jack Dempsey is an intensely colorful and extremely hardy Cichlid native to still and slow moving bogs, lakes, ponds and swamps in Central America.
They are one of the most popular species in the hobby and are known for their territorial instincts as well as the intense coloration they can bring to any aquarium. They have a gray-blue base color with vivid, iridescent, electric blue to purplish scales mosaicked with dark to black coloration. Electric Blue Jack Dempsey can also have (to varying intensity) black splotching on their lateral lines. Males will also grow out to be much larger than the females.
How to successfully keep Electric Blue Jack Dempsey in the home aquarium.
Electric Blue Jack Dempsey require an aquarium of at least 55 gallons and should be provided with multiple places where they can find shelter (driftwood, rock structures (especially caves), and dense vegetation). In addition to a good hiding place, Electric Blue Jack Dempsey appreciate clean, acidic to neutral water as well as live plants, but have been known to dig, which will cause some uprooting.
While they can be quite territorial and aggressive as they grow in size, which can lead to weaker or smaller fish being bullied, they can be kept with a wide range of fish species who have a similar size and temperament. Tank mates should be considered carefully with the size of the aquarium, amount of available territory and long term compatibility based on the adult fish size and temperament taken into consideration.
