The harlequin rasbora belongs to the carp family\n(cyprinidae), and within this to the danios (danionidae). Its scientific name\nis trigonostigma\nheteromorpha <\/em>(until 1999\nit was known as rasbora heteromorpha<\/em>).<\/em> \u201cHeteromorpha\u201d comes from\nthe fact that its shape differs slightly from that of other danios, with a\ndeeper body.<\/p>\n\n\n\n
The harlequin rasbora is sociable, an active swimmer and one\nof the most popular aquarium fishes. It originally comes from Malaysia,\nIndonesia, Sumatra and Thailand, where it can be found in large shoals in\nblack-water swamps and streams. It was discovered in 1904 and the first wild\nfish were imported to Europe in 1906.<\/p>\n\n\n\n
It is easily recognisable thanks to the black triangular patch\nthat starts below its dorsal fin and extends to its tail fin. Its silver scales\nalso give off a reddish to copper sheen. The shimmering colours of its\nrelatively large scales earned it the name \u201charlequin rasbora\u201d. <\/p>\n\n\n\n
The males tend to be a little slimmer than the females.\nTheir triangular patches also differ. While the patch ends at the root of the\ntail fin in females, it continues through to the middle of the tail fin in\nmales.<\/p>\n\n\n\n
Harlequin rasbora: Aquarium and water<\/h2>\n\n\n\n
To create an appropriate habitat, these peaceful shoal fish\nshould be kept in an aquarium of at least 54 litres. In accordance with its\nnatural habitat, the harlequin rasbora feels most at home in black water. The\nbest way to give the water a dark, slightly acidic quality is to filter it over\npeat or add peat extracts. Wild harlequin rasboras live in very soft water of\nbelow 3 \u00b0dH. However, bred harlequin rasboras now cope very well in neutral or\neven slightly hard water.<\/p>\n\n\n\n<\/figure>\n\n\n\n
In the wild, harlequin rasboras form loose social groups \u2013\nto ensure that they feel safe and show their entire range of behaviour, they\nmust be kept in groups of at least eight to ten fish. The group also brings out\nthe colour of their dark triangular patch against its silvery background. If\nthe fish are happy, they can live for up to six years.<\/p>\n\n\n\n
Their peaceful nature means that harlequin rasboras can be\neasily kept with other fish; the best options include labyrinth fish, loaches\nand other danios.<\/p>\n\n\n\n
Harlequin rasbora: Planting and decoration<\/h2>\n\n\n\n
Trigonostigma\nheteromorpha<\/em> likes a dark aquarium with a smattering of vegetation. It\nneeds both places to hide and open spaces to swim. Its colours look best in\nmuted light (achieved, for example, with a covering of floating plants) with a\ndark substrate.<\/p>\n\n\n\n
If you wish to breed these freshwater fish, you will need to\ntake their reproduction strategy into account when choosing plants: they\ngenerally lay their eggs on the underside of broadleaf plants. Suitable plants\ninclude cryptocoryne and swampweeds (hygrophila). If planning to breed fish,\nyou will also need to think about water hardness, which must be very low. The\npH level must be slightly acidic. Therefore, these are not easy fish for\nbeginners to breed.<\/p>\n\n\n\n
Harlequin rasbora: Diet<\/h2>\n\n\n\n
These fish will eat almost any form of dry food. You can\nmake them particularly happy by regularly feeding them live food. They\nparticularly like black bloodworms. <\/p>\n","protected":false},"excerpt":{"rendered":"
