Hey. Just wanted to know. What conditions should I be giving my Danios in order for them to breed? Any specifics? Cause I've had 8 for quite a while and recently lost 3. What should I do to breed them well?

Danios are relatively undemanding. You do not need to do anything to breed them. Get a spare tank and place plenty of Java moss or 2-3 layers of marbles at the bottom. Put water at half level. As the eggs are heavier than water, this will allow the eggs to fall quickly to the bottom thus avoiding predation. Remove the adults once done.
Sexing:
In mature specimens, the males are much slimmer than the females. If comparing two wild-type D. rerio of opposite sexes, the background will be more golden on a male and a paler yellow on a female.
Breeding:These are reputedly among the easiest egg-layers to breed, perhaps easier than the White Cloud Mountain Minnow (Tanichthys albonubes) and the Convict Cichlid (Archocentrus nigrofasciatus). Depending on your view, you may choose to use mated "pairs" or you may choose to condition all of them and merely pick a female and a male. Merely heating the water to a temperature in the mid to upper 70s Fahrenheit and oxygenating it somewhat will likely trigger a spawning response. (I believe that this simulates a rainy season and the unification of their stagnant pools to the rivers of the area.) Another aspect of breeding D. rerio which has multiple schools is the adornment of the spawning tank. Some recommend a heavily-planted display tank and just allowing the young to grow up along side their parents in single-species tanks. Or floating plants may be used in such a tank and then removed to a separate incubatory tank. Others recommend layering the bottom of the spawning tank with marbles so that, once-scattered, eggs will not take on the role of sustainence for the hungry parents. The fry can then grow unmolested in the rearing tank once the parents have been removed. Specially feeding the fry, if such is desired, will be most easily done with a culture of infusoria and fry foods intended for egg-laying fish.
