Electric Blue Jack Dempsey EBJD
The Electric Blue Jack Dempsey cichlid Rocio octofasciata cf. (previously Cichlasoma octofasciatum) is considered to be one of the most beautiful freshwater aquarium fish. The adult displays a magnificent blue coloration, and is definitely one of the ‘bluest’ freshwater fish in the hobby. It has a dark brown background that is covered with brilliant metallic and iridescent blue flecks. It will reach a maximum length of a little more than 8″ (20 cm), or slightly smaller than its genetic progenitor,the Jack Dempsey.These fish are also called the Blue Dempsey, Electric Blue Dempsey, and Jack Dempsey Neon Blue.
This dazzling fish is a naturally occurring variant of the Jack Dempsey. According to popular rumor, fry which displayed the bright blue coloring of the Electric Blue Jack Dempsey were considered to be malformed and runtish and were discarded by their keepers as inferior specimens. Fortunately for those hobbyists who appreciate the stunning coloration of these fish, and for the hobby in general, this archaic and incorrect view has been largely discarded and these fish are now being actively bred and developed in captivity. Though the Blue Dempsey is relatively easy to breed, it does take a considerable amount of time, luck, and a well designed aquarium set up, so these fish are rather rare and quite a bit more expensive than many other tropical fish, include the Electric Blue Jack Dempsey’s progentitor species, the Jack Dempsey.
The Blue Dempsey is a bit more delicate than its parentage. But just like its progenitors, it likes a tank bottom of fine sand to burrow in and create nests out of. It also needs plenty of hiding places among rocks and wood, and a cover of floating plants. However they will enjoy snacking on any plants in the aquarium, so it is reccommended to monitor the status of any plants sharing the tank with a Blue Dempsey.
This cichlid, true to its family, tends to be semi-aggressive and will appreciate being kept in a large aquarium with similarily sized and tempered tankmates. That being said, it generally is not quite as aggressive as many cichlids and can be shy at times. Thus, it is best to either keep it singly or in a large group with only a few other tankmates.
