4-5” Jack Dempsey

4-5” Jack Dempsey – Robust and Vibrant Freshwater Cichlid

The 4-5” Jack Dempsey is a striking freshwater fish renowned for its vibrant colors and engaging personality. Named after the famous boxer due to its aggressive stance, this cichlid is a popular choice among aquarium enthusiasts looking for a hardy and visually captivating centerpiece fish.

Size and Appearance

At 4 to 5 inches, the Jack Dempsey reaches a moderate size suitable for medium to large aquariums. Its body is adorned with iridescent blue and green spots that shimmer against a darker base color, creating a beautiful contrast. As Jack Dempseys mature, their colors deepen, making them increasingly attractive.

Temperament and Behavior

This species is known for a semi-aggressive temperament. While not excessively hostile, Jack Dempseys can be territorial, especially during breeding. They are known to display assertive behavior toward tank mates, so understanding their compatibility is crucial when planning your aquarium community.

Recommended Tank Size

Given their size and activity level, a minimum tank size of 55 gallons is recommended to provide adequate swimming space and reduce territorial aggression. A larger tank also allows for better water stability and more natural behavior expression.

Water Parameters for Optimal Health

• Temperature: 72-86°F (22-30°C)
• pH Level: 6.5-8.0
• Hardness: 9-20 dGH

Maintaining stable water conditions within these parameters ensures the Jack Dempsey remains healthy and vibrant. Regular water changes and proper filtration are essential for their well-being.

Diet and Feeding

Jack Dempseys are omnivorous and thrive on a varied diet. High-quality pellets or flakes formulated for cichlids form an excellent base. Supplement their diet with live or frozen foods like bloodworms, brine shrimp, and earthworms to mimic natural feeding habits and enhance coloration.

Compatibility with Other Fish

Due to their semi-aggressive nature, Jack Dempseys do best with similarly sized, robust tank mates. Avoid smaller, timid species that may become stressed or preyed upon. Suitable companions include other Central American cichlids, large catfish, and plecos. Providing plenty of hiding spaces and decorations can help reduce conflict.
