Harlequin

Origin

Harlequin fish (Harlequin rasbora) is one of the most beloved aquarium fish.
It can be found in Asian waters. It belongs to the order Cypriniformes, family Cyprinidae, genus Rasborinae.
Both in the natural environment and in the aquarium prefer dark substrate and natural light. They need both a spacious Aquarium in which there is vegetation to hide in and ski areas for swimming.
The name Harlequin fish comes from the triangular drawing, black, which comes in contrast to the other colors. The scientific name comes from the Greek language and means "with different shape".

Feeding over Harlequin

It is an omnivorous fish. It can be fed with almost any type of feed for aquarium fish. It's not a demanding species so food won't be a problem.
It is good to vary the food in time for the fish to gain immunity.
Pay attention to Tubifex. If it is not purchased from appropriate places it can come with diseases to pack. Personally I had no problems when feeding fish with these tubifex worms , but many breeders confirm that they can be carriers of various diseases.

Appearance over Harlequin

It can reach lengths of 4-5 cm.
It is a small fish with a rhombus-shaped body whose basic color is orange-pinkish from the head to the caudal fin. In the posterior part of the body it has a triangular drawing of black color, starting from the middle of the body and ending on the caudal fin.
Color intensity is influenced by environmental factors such as water quality. The color of the dorsal, caudal and anal fins is red, the latter being more pigmented and, in the rest, transparent.
Males are weaker than females and have curved black stripes. The black stripe of the females is perfectly straight.

Features over Harlequin

In the natural environment they live in large shoals and it is recommended in aquariums to be at least a few specimens (5-10) of the same species.
It is a relatively common aquarium species that can live with other fish because it tolerates other species very well.
In order for the development to be correct, an aquarium of 50 – 100 liters is recommended.
If we take exception to the fact that their reproduction is relatively difficult they are recommended fish for beginners.

Breeding over Harlequin

It is a species of fish that is quite difficult to reproduce in captivity, but not impossible.
If all conditions are created the fish will multiply. It is recommended to grow and multiply them in shoals. For competitiveness it takes at least two males to a female.
The water temperature should be 24-28 degrees.
The male may push the female slightly from the side and rub her belly against her side to direct her to the mating location. As the eggs are released the male will approach and fertilize them.
It usually catches the eggs by the leaves in the environment.
After spawning and fertilization it is good to remove the adults from the aquarium because they can eat the newborn chicks. They reach maturity 9 months after birth.
