What size tank are they in? Hopefuly it's at the very least a 15 gallon and has already been cycled.
The first thing you need to know is that these are fragile fish in that they often carry disease and are prone to internal bacterial infections. They can also be quite shy when first introduced to a tank and need plenty of hiding places and a gentle current.
Males are territorial and all dwarfs preffer the upper levels of their tank when healthy. It is a very good idea to include some floating - opr at least tall-growing - plants in the tank.
If you want them to breed, you need to be prepaired to move the females out directly after spawning and, later, to move the male out as well. This is extremely stressful for the fish and the tank they are transferred to must already be cycled. The fry are very small and need to be fed on baby brine shrimp or microworms or vinegar eels etc. They won't usualy survive off flake food.
To bring dwarfs into breeding condition, you need to raise the tank's temp. to about 80 deg F and feed lors of live foods such as bloodworm. It helps to seperate the male from the females during this conditioning time and sometimes it helps to lower the water level in the breeding tank.
Eventualy the male will build a bubblenest and attempt to entice the female under it. If she is gravid (full of eggs) she'll look blump (but don't mistake dropsy - a symptom of disease - for being gravid!) she is likely to comply and the pair will 'embrace'. The female releases the eggs, the male fertilises them, puts them in the nest and then starts chasing all itnruders (including the female) away while he guards the nest.
Males can become rather aggressive at this time. For this reason and to make it easier to feed the fry, it can help to set up a seperate breeding tank instead of attempting to spawn within a community (note that fry get eaten in a community setting anyway - they can also get killed by the filter so a sponge filter is reccomended).
Try searching the gourami section - dwarfs breed in the same manner as pearls, three-spots, honeys and most other common species.
