They can get along with other peaceful fish, entirely unlike themselves, but with rather large sizes like Tetra fish, kuhli loach, catfish, gourami, synodontis catfish, tiger barbs (except Sumatran).


You cannot settle two males on the same territory (especially small). Otherwise, there will simply be deadly battles. You can keep a couple together, but for the female, You need to build more shelters.

Maintenance and Care

The maintenance of paradise fish does not take much time, they can live in a simple five-liter jar, but they will not grow to their natural size – the capacity is small.

Care must meet the following requirements:

  • The aquarium for one pair must be at least 40 liters in volume. It should be covered with a lid or glass – the fish are very jumpy and can easily find themselves outside the aquarium. The distance from the water to the aquarium cover should be 6-8 cm.
  • The temperature regime should be in the range of 20-26 degrees Celsius, but tenacious paradise calmly tolerates a drop in temperature to 16 degrees.
  • Acidity 6.5-7.5.
  • Hardness – 5-25.
  • Aeration and filtration: Fish do not need ventilation. Like all labyrinths, these fishes also breathe air but still, Aquarium Filter is required. It is recommended to install an internal aquarium filter, setting its mode to a minimum so that water fluctuations are not too sharp—paradise fish likes stagnant water. A mandatory weekly water change is recommended, about 20% of the volume of the aquarium.

Aquarium Decoration

Priming: You can fill the bottom with river pebbles or coarse sand. Dark marble chips are also suitable; against its background, the fish will look brighter and more exotic. The height of the soil should not exceed 4 centimeters.

Lighting: It should not be too bright, usually use fluorescent lamps that attach to the lid of the aquarium. Light is needed for plants for active growth and fish so that the color always remains bright and attractive.

Plants: are planted in the background so that the fish can swim freely. Usually planted Ceratophyllum, Elodea, Vallisneria to females was where to hide from the harmful males.  There must be free space on the surface of the water so that the fish can breathe.

The aquarium must contain live plants. For the decor, several artificial ones are added, as well as shells, castles, boats, decorative snags.


Paradise fish are omnivores, and feeding adults is not difficult. But the owner needs to keep in mind that these are still predators, so live, or frozen feeds should predominate in the diet:

  • bloodworm;
  • Artemia;
  • pipe maker;
  • Drosophila flies;
  • small crustaceans.

Fishes in the absence of live food feed well on the dry fortified feed. Infrequently they should be offered minced meat or fresh cucumber. They can also eat snails or planarians.

Feed twice a day in small portions. The main thing is not to overdo it. Predators should always be a little hungry.


The fish can breed as early as 8–9 months. For planned breeding, a small spawning aquarium is prepared in advance. 7-10 days before the landing of the females and males are separated and fed only with live food.

The male is the first to start in a day, make a water change (about a fifth of the total volume), raise the temperature to 26–29 degrees, and only then the female is placed.

The male and female begin mating games, and then, dad builds a nest from air bubbles and floating plants. Then invites the female for spawning. He gently helps his girlfriend by wrapping himself around her and squeezing out eggs, which he immediately fertilizes.

At one time, the female spawns up to 1 thousand small yellowish eggs, which dad collects and places in the nest. After this, the female should be immediately removed. Otherwise, she risks being crippled. Further, only the father takes care of the masonry.

Paradise Fish Fry

Fry appears after 24 hours and, after 3-4 days, become independent. Then the male is precipitated; he can eat or harm the fry if he feels danger.

Juveniles are fed with nematodes, microworms, artemia nauplii, alternating with the chicken and yolk. Typically, most of the eggs and fry die. Survivors are sorted and transplanted into a standard aquarium, leaving active fish with the correct body shape and bright color.

Frequent spawning is undesirable for the male; the fish may die from exhaustion. Throughout one’s life, Paradise fish is not recommended to be allowed to spawn more than three times in a row. To reduce the number of spawning in the aquarium, a strong current is created, and almost all vegetation is removed.
