Spotted Rasbora

Also known as the Dwarf Rasbora, the Spotted Rasbora originates from Southeastern Asia where it can be found in Singapore, Thailand and Malaysia. This species varies in coloration depending upon its natural habitat, but most specimens have a silver body ornamented with large black spots near the fins and tail.The Spotted Rasbora remains small and can be housed comfortably in small aquariums. These fish are compatible with other small, peaceful species of fish but are not suitable for community tanks due to their timidity.

Tank Set-Up

Spotted Rasboras are shoaling fish, best kept in groups of eight or more. Larger groups may result in more active fish and more vibrant coloration. These fish prefer densely planted tanks decorated with driftwood and rocks to provide hiding places as well as floating plants to dim the lighting in the tank. Spotted Rasboras prefer dark substrate, low filtration and can be very sensitive to changes in water chemistry. These fish are best kept in already-established tanks having a low pH and some level of tannins in the water to simulate their natural environment.

Feeding

These fish are micropredators in the wild, feeding on zooplankton, crustaceans, worms and small insects. In captivity, Spotted Rasboras should be offered a staple diet of high-quality flakes or pellets. This diet may be supplemented with live and frozen foods such as brine shrimp, Artemia and Daphnia to encourage their best coloration.

Breeding

Spotted Rasboras are not easy to breed in the home aquarium but may spawn in well-planted permanent breeding tanks. These fish are egg-scatterers and exhibit no parental care. Because they eat their own eggs and fry, Spotted Rasboras should be removed from the breeding tank after spawning. Once spawning has occurred, the eggs usualy hatch after 24 to 48 hours and will become free swimming after another 24 hours.
