Electric Blue Jack Dempsey Cichlid – Freshwater Fish

The Electric Blue Jack Dempsey is a spectacular Central American cichlid featuring brilliant metallic-blue coloration, contrasting dark markings, and an unmistakable shimmering appearance. It provides the intense color normally associated with marine fish while living entirely in freshwater.

This selectively bred color form of the traditional Jack Dempsey makes an impressive centerpiece for an appropriately sized freshwater aquarium. Electric Blue Jack Dempseys can be more sensitive than standard Jack Dempseys and are best maintained by aquarists who can provide stable water conditions, quality nutrition, and carefully selected tank mates.

One small-to-medium Electric Blue Jack Dempsey Cichlid is included.

Aquarium Requirements

Provide a fully cycled aquarium with stable parameters, strong biological filtration, and sufficient swimming space. Electric Blue Jack Dempseys appreciate caves, driftwood, rocks, and other structures that create secure territories.

Arrange decorations carefully and leave open swimming areas. All rocks and structures should be stable because larger cichlids may dig or rearrange the substrate.

Electric Blue Jack Dempseys may be more delicate than standard Jack Dempseys. Consistent temperature, regular water changes, low nitrate levels, and excellent water quality are essential.

Feeding

Offer a varied diet of quality cichlid pellets, frozen or freeze-dried krill, mysis shrimp, brine shrimp, insects, and other appropriately sized foods.

Avoid relying exclusively on feeder fish. A varied prepared and frozen diet provides more balanced nutrition while reducing the risk of introducing parasites or disease.

Feed only what the fish can consume within a few minutes and remove uneaten food to maintain water quality.

Temperament and Tank Mates

Electric Blue Jack Dempseys are semi-aggressive and may become increasingly territorial as they mature. Provide adequate aquarium space and secure territories to reduce conflict.

Potential tank mates include similarly sized, robust fish with compatible water requirements. Avoid very small fish that may be eaten, delicate species that may be bullied, and extremely aggressive cichlids that could injure the Electric Blue Jack Dempsey.

Compatibility is never guaranteed. Individual behavior should be monitored carefully, particularly as the fish matures or begins forming a pair.

Acclimation

Keep the aquarium lights dim or turned off during acclimation. Gradually acclimate the fish to the aquarium’s temperature and water conditions, and never add shipping water to the main aquarium.

Provide a quiet environment after introduction and allow the fish time to settle before offering food. Temporary hiding or reduced coloration may occur while it adjusts.

Fish Quarantine

This fish will ship within a 14-day quarantine window, depending on its current stage of quarantine.

Please allow additional processing time before shipment. Tracking information will be provided once the fish has completed preparation and has been transferred to the carrier.
