The Jack Dempsey is a type of cichlid, and one of the most popular tropical fishes kept as pets. 

These fish can be tricky to keep, so you need all of the information you can get. It is crucial that you educate yourself before getting one of these cichlids so you will be prepared.

Jack Dempsey Fish Appearance

This particular variety of cichlid gets its name from its distinguished face, which some have compared to famed boxer Jack Dempsey. They have a number of other defining physical characteristics, including an oval-shaped body and long fins. These fish are very striking with a multitude of colors that include blue, black, yellow, and orange.

Not all of these cichlids have the same combination of colors, so they are all at least a little unique. The older they get, the more prominent their blues and purples become. These fish can partially change color when they are stressed or during the mating process.

The males have especially long dorsal and anal fins with a distinctive point, while the females have shorter fins that aren’t quite as remarkable. These fish can grow up to 15 inches, but females tend to be a little shorter than males.

Behavior

The aggressive tendencies of tetra fish are one of the reasons that they can be so tricky to keep. The more fish mates they have, the more docile they are. This is because they have trouble targeting one fish in particular.

If you are going to keep one of these tetras, you will need at least an 80 gallon tank. While these fish are not big swimmers, they are fairly large and need plenty of space.

Use a soft material like sand for the substrate. You don’t want to choose a material that is even slightly abrasive, as these fish spend a lot of time at or near the bottom of tank.

2. Water Conditions

You should keep the temperature of the water inside of the tank between 72 and 86 degrees Fahrenheit. A water hardness of 9 to 20 dGH and pH of 6 to 7 is ideal.
