Dealing With Danios By Deborah & Rodney RALPH
Breeding the Zebra Danio - Brachydanio rerio, and Leopard Danio - Brachydanio frankei was easy because we did the same thing almost for both species. We used a breeding trap placed in a tank with a 6 gallon (27 litres) capacity, with gravel the first time and no gravel the second time - for no reason in particular. The water temperature was 26 degrees celcius and of a neutral pH. A male and female Golden Long-finned Zebra Danio were spawned first and a few months later Long-finned Leopard Danios using one female with 2 males this time, we got more fry as more eggs were fertilised.
They were not placed into the traps until they were very ripe and as luck would have it, both lots had not been in the trap any longer than 24 hours before spawning took place. To get a good quantity of fertilised eggs we left them in tor two to three days then the parents and trap were removed. The eggs hatched in 2 days and in another 2-3 days were free swimming.
Infusoria, liquifry and Sera micron food were given until they were big enough to accept newly hatched brine-shrimp, small daphnia, cyclops and dried food. With this type of food their growth is quick and relatively troublefree.
