Rasbora Dorsiocellata | freshwater fish

INFORMATION:

Classification:

Order: cypriniformes

Family: cyprinidae

Distribution:

Native to southern Thailand, peninsular Malaysia and the Greater Sunda Islands of Borneo and Sumatra. The type locality is 'Muar River, Tebinh Tinggi, Johore, Malaysia'.

In Peninsular Malaysia, localities include the Selai and Muar rivers in Johor state and the blackwater swamp lake of Tasek Bera in Pahang state, while in Sumatra the only report we have been able to find appears to refer to the Lalah River, Riau province in the east of the island.

It was once thought to be restricted to the southern (Indonesian) parts of the island and has been recorded from several rivers and streams within the lower Kapuas River and Ketungau River basin in West Kalimantan Province (Kalimantan Barat), as well as in the tributaries of the Sebangau and the lower. Mentaya Rivers in Central Kalimantan (Kalimantan Tengah).

However, it seems possible that some or even all of the Kapuas records actually refer to Brevibora cheeya.

Until a scientific comparison is made between the shapes of island and mainland species, the truth is unlikely to be known.

In any case, wild-caught fish are quite rare in the hobby, as the species is produced commercially in several countries.

Habitat:

It primarily inhabits gently flowing blackwater streams and rivers associated with old-growth peat bogs.

The water turns brown due to the release of tannins and other chemicals released by decaying organic matter and the substrate dotted with fallen leaves, twigs and branches.

Such environments characteristically contain very soft (negligible hardness), acidic (pH as low as 4.0) water, and often have little light due to the forest canopy above.

Its size is:

30 – 35mm.

Parameters required:

PH: between 5.0 and 7.5

Temperature can range between 20-25°C

Aquarium size:

A group will need an aquarium with base dimensions of 45 * 30 cm or more.

Feeding:

It is a micropredator that feeds on small insects, worms, crustaceans and other zooplankton.

In the aquarium, he will accept dry food of a suitable size, but ideally he should be offered daily meals of small live or canned foods, such as Daphnia, Artemia and the like.

Behavior:

This species is very peaceful, making it an ideal resident of the well-chosen community tank.

As it makes no special demands in terms of water chemistry, it can be combined with many of the most popular fish in the hobby, including other small cyprinids, as well as tetras, livebearers, dwarf cichlids, catfish and loaches.
