Background of Paradise fish

The Paradise Fish (Macropodus opercularis) was described by Linnaeus in 1758. It belongs to the family Osphronemidae under order Perciformes of class Actinopterygii. It was introduced to the hobby by a French soldier Gerault in 1869. It is often referred to as the ‘founding fish of the hobby’. It is small but very attractive and beauty fish among the freshwater fish keepers. The genus Macropodus is derived from Greek words ‘macros’ means great and Greek ‘podos’ means foot. It is listed on the IUCN Red List as Least Concern (LC).

Feeding Paradise fish

The paradise fish is omnivorous and in wild it feeds on small fish and other small aquatic animals including planktonic invertebrates and other zoobenthos. In captivity it accepts wide variety of foods such as frozen bloodworms, mealworms, mosquito larvae, small earthworms, shrimps and plankton. It also takes nearly any foods designed for salt water fish. To keep your fish healthy give them a quality flake or pellet food as the base of the diet. Generally feed should be offered once or twice a day.

Housing Paradise fish

It is a hardy fish and makes a good choice for the all type fish keepers. They make very personable and attractive aquarium inhabitants. It requires at least 20 gallons tank for a single male or 20-30 gallons for a community tank. Male should be kept singly or in pairs with lots of hiding places for the female while females can be kept in groups. The aquarium should be heavily planted with floating plants. The tank should also have an efficient filtration system with very gentle water movement. Gouramis should not be kept with large, aggressive fish but are compatible with other small, peaceful fish such as medium to large gouramis, robust cyprinid species, larger characins, Geophagus cichlids, loricariid catfish, large Synodontis catfish and loaches. It should not be kept with slow swimming fish or fish with long flowing fins. The tank needs to be covered as they are jumpers and regular water changes should be done to make your fish healthy.

Breeding Paradise fish

The paradise fish is bubble nest breeder and it can easily breed in captive condition. The spawning tank must have plenty of hiding spaces like rocks, caves and plants. The male builds a bubble nest on the surface of the water usually interspersed with floating vegetation or under a leaf on the surface.  The female produces about 500 eggs.  The eggs are lighter than water and float up into the nest. The male picks up the fertilized eggs in his mouth and pushes one by one into bubble nest.  After spawning, the male becomes extremely aggressive towards the female. At this point the female should be removed from the breeding tank and the male left to take care of the eggs and fry. The eggs normally hatch in 24 to 36 hours. The free swimming fry can be fed with infusoria, baby brine shrimp and micro worms.

Sexing Paradise fish

The male is far more colorful than the female and develops long filamentous anal and dorsal fins at maturity. Female becomes fuller bodied with eggs and more dull in color. Male also tends to be larger than the female of the same age.
