They can be reared with other gentle small tropical fish. According to the changes of different species, the water temperature suitable for the growth of Rasbora heteromorpha also changes, generally floating between 23-28 degC.

    1. Harlequin Rasbora

    The Harlequin rasbora was first produced in the rivers of Thailand, Indonesia, Malaysia and other countries in Southeast Asia and other places.

The bright golden yellow color is matched with the small and sensitive fish body, which has a certain degree of appreciation and is also very attractive.

    Trigonostigma Somphongsi imports are very scarce in the country, because they do not have the most prominent feature of the triangle fish, triangles, and are not as thick and colorful as the Trigonostigma Espei, which causes it to be almost mixed with other triangle lights. Imported from the variety, it is not easy for players to find in the ordinary fish market.

According to the natural environment of its place of origin, the suitable temperature for the growth of purple delta fish is about 22-28 degC, the pH value of the water quality is about 6.0-6.6, and the hardness is about 1-3 degrees. General rainwater can be used for feeding The water used by the purple triangle fish. Like many lampfishes, the purple triangle lampfish prefers soft old water. The water temperature should not change more than 2 degC. The temperature difference between day and night should not be too large.
