Rasbora: Rasbora, an Indian word for a fish, also used in Malay peninsula
A good community fish with other small rasboras, danios and tetras. In a tank with good water circulation but with out strong currents. Rasbora borapetensis is a shoaling fish and does best when kept in a group of at least five individuals. Their aquarium should be well planted but with open swimming spaces. Rasbora borapetensis is sometimes found in slightly polluted water which demonstrates the hardiness of the fish. This is an ideal species for your first community aquarium due to its nature, looks and ease of keeping.
Wild Rasbora borapetensis are micro predators feeding on insects, worms, crustaceans and zooplankton. In captivity they will thrive on good quality flake food and suitably sized live or frozen food.
When adult the males are smaller and slimmer but have more vibrant colours than the females
For breeding this fish use a separate breeding tank which is bare apart from one or two bunches of fine leaved plants and filled with aged water and a temp of 26°C (79°F). Introduce a well conditioned pair or trio (one female - two males) which will usually spawn without difficulty. Remove the parents after spawning and introduce a mature sponge filter to the tank. The fry once free swimming will initially feed on infusoria or a commercial liquid fry food and after a few days they will be big enough to accept baby brine shrimps or finely crushed flake food.
Rasbora borapetensis has a large natural range which has been increased further through introductions in to other Countries. Most fish in the aquatic trade are farmed with relatively few wild fish being caught. The wild status of Rasbora borapetensis hasn't been evaluated but due to the wide range and facing no immediate threats there needs to be little concern over wild populations.
