danios are not at all picky about who their mate is and they spawn primarily in the early morning.
females will have rounded bellies and are slightly larger. males will have a golden base with horizontal stripes laid across them. males are more streamlined. make sure you have both, of course. you may want to increase the school to 6 or more. it is possible that you only have males or you only have females, in which case you will be waiting a very long time. i would add three more at least
danios eat their eggs when they spawn; they love them. to get any to survive you need to have large substrate, where the eggs can fall in between it, trapped and out of reach of the parents. marbles or very large gravel work for this....also, having a lot of plants can help. if you can put them into a breeder tank with a sponge filter, in the early morning, using marbles or large substrate, you will have no trouble.
if you have males and females, you can be sure that they are spawning each and every morning. watch them early in the morning and the males will sideswipe the females and look like they are trying to run them off the road, so to speak.
hope that helped
