Dwarf rainbows are a schooling fish---they will do much better in a group of their own consisting of 5 or more. They will go about the tank in their own direction, but will school tighter while under stress, or in the presence of dither fish. They swim in the middle to upper stratus of the tank, but will venture to the bottom if in search of food (i.e., algae tab). For breeding, it is almost a must to have fine featherly-like plants for the female to scatter her eggs about. The male will exhibit bolder colors while chasing the female around.
