Keeping of Axelrod’s rasboa, Sundadanio axelrodi
Sundadanio axelrodi is also called Rasbora axelrodi. It comes from Sumatra and is about 2 centimeters long. There are red and blue color forms. Sundadanio axelrodi is a schooling fish and is also suitable for small aquariums. it really comes into its own in a larger swarm of 20 to 30 animals. The planting should be partly dense, but leave enough free swimming space. The water should be soft and slightly acidic. The temperature should be 23° to 26° C. The coloring works better on a dark background.
breed
Breeding is similar to breeding harlequin barbs, Rasbora heteromorpha. A couple is placed in soft and acidic water with a pH of 6.5 and a carbonate hardness of 0 dKH. Slightly different specifications are pH 5.3 – 5.7 and 1.5 – 2.5 dH. The water can be weakly filtered through peat. The breeding tank is dimly lit. 30 to 200 eggs are spawned on slender plants. The parents eat their own spawn. The young hatch after 24 hours.
After 3 to 5 days, the young swim freely. At first they are very shy of light and stay on the ground. The water level can be lowered to 10-12 centimeters after spawning. The young must be adequately supplied with live food, e.g. B. with rotifers and artemia nauplii. When fed with fine, freshly hatched artemia, the young grow rapidly. The water in the rearing tank should be changed as often as possible.
If a breeding pair does not spawn, other partners should be tried. Spawning often takes place only a few days after assembly. For many rasbora, sunlight stimulates spawning.
