Family
Cichlidae
Origin
Found mainly on the swampy slow moving rivers and canals of Central America.

Aggressive in smaller tanks, but it can be fairly peaceful in a large enough tank.
Maximum Size
8-10 inches (20.32 -25.4cm)
Minimum Tank Size
55 gallon for one, by itself.
Tank Setup
They need a lot of space for swimming. Gravels with some rocks are suitable for decoration but plants will not work as they will uproot them. Requires a good filtration as they are messy eaters. Perform 25-30% water change every week.
Tank Region
Bottom to mid dweller.
Diet
Jack Dempsey is carnivorous in nature .Feed them a good mixture of high quality cichlid pellets, krill, frozen bloodworms, earthworms, crickets, etc. Feed them 2-3 times daily to enhance the blue colour.
Breeding
If you have a pair, then it is obvious that you will have some fry. Try a breeding pot or a cave so that the female can lay the eggs. Eggs can vary in number in between 500-600. They are bi-parental and will protect the fry from danger. It is best to move the mated pair in a breeding tank as they become very aggressive towards other tank mates.
Compatibility
It is best to keep them with same species only. But they can be kept in a community if the tank is large enough, 125g or bigger.
Ease of Keeping
Easy to keep and are hardy in nature.
Care
pH: Doesn't matter; Temperature-72.0 to 86.0° F (22.2 to 30.0° C). Since they are messy eaters Canister Filter is really good for them.
