Fish - Rasbora - Sundadanio axelrodi

Distribution
Supposedly native to the Greater Sunda Islands of Borneo and Sumatra as well as the Riau Archipelago and Bangka Island off the east coast of Sumatra but the only collection/locality details we have been able to find refer to Bornean populations. Numerous records also exist from the Indonesian provinces of West Kalimantan (Kalimantan Barat), Central Kalimantan (Kalimantan Tengah) and South Kalimantan (Kalimantan Selatan) but the species appears not to occur in the north of the island.
It exists in several colour forms depending on locality; fish from the south and east of Sarawak state in Malaysian Borneo are green/blue in colour while those found in the west are red/orange, for example. It would be useful if these variants were labelled with the collection details by hobbyists and scientists alike in order to preserve bloodlines and maintain greater accuracy although normally they are just labelled with the distinguishing colour eg. ‘red’, ‘green’ or ‘blue’.
Habitat
Inhabits black water streams and pools associated with ancient forest peat swamps. The water is stained brown due to the release of tannins and other chemicals released by decomposing organic matter and the substrate scattered with fallen leaves, twigs and branches. Such environments characteristically contain very soft (negligible hardness), acidic (pH as low as 4.0) water and are often dimly-lit due to the forest canopy above and dense marginal vegetation. Across much of Southeast Asia these precious biotopes are under threat from rubber/palm oil plantations, building developments and other human activities.
Maximum Standard Length
20 – 22 mm.
Aquarium Size
A group can be housed and will breed in a tank with dimensions of only 12″ x 8″ x 8″/30cm x 20cm x 20cm/12.5 litres although water quality may become an issue unless strictly monitored. We think something measuring around 18″ x 10″ x 10″/45cm x 20cm x 20cm/29.5 litres or more is preferable for long-term care.
