Family: Cyprinidae
Distribution: Rasbora borapetensis, commonly known as Blackline Rasbora, is an Asian freshwater species found in the Chao Phraya, Mekong and Meklong basins, and in the northern Malay Peninsula; it is distributed in streams, drains and ponds – usually in slow, turbid waters.
PH: 6.5 – 7.0
Temperature: 22°C – 26C (72 – 79F)
Hardness: 5 – 12 dH
Description: Rasbora borapetensis can reach a maximum length of around 6 cm. This streamlined, silver fish has a distinctive dark brown or black stripe that stretches from its gills to the front of the caudal fin base. Directly above the black line is a golden stripe. It has a caudal fin that is bright red; the two sexes are remarkably similar but females are a bit bigger than males.
Diet: This omnivorous species will accept most foods in an aquarium environment, including live foods, frozen foods, flake and dried foods.
Breeding: This egg-laying species will require daily water changes and live food to spawn. Females will produce 30 – 40 eggs; it is probably a good idea to remove the adults as soon as you see the eggs as they will definitely try to eat them. The eggs hatch in around 36 hours and the young will be feeding two days later.
Comments: You could probably house a small group of Blackline Rasbora in a 12 gallon tank. Your tank should have plenty of open swimming space, as well as being densely planted and as dimly lit as possible; provide floating plants at the top of the tank for shade. This species is suitable for newcomers to the hobby.
