Install a 50-litre aquarium fittedwith an angled filter and cover the bottom a thick padding of java moss. And some broad-leafed Anubias genus plants and wait until a pair persents themself in your aquarium. introduce them into there new home, then start to adjust the water to obtain a hardness of 2 dH and a pH of 6.5. in order to do this, use peat filtered rainwater to maintain a pH value lower then neutral.
the pair should start the mating project. the emitted eggs are immediately fertillised and attached to the underside of a leaf. at this stage, darken the aquarium becaue the eggs cannot stand the light, and take the parents out once spawning is finished, the fry will swim freely after about 5 days and must be fed with fine plankton, then with brine srimp nauplii...
good luck....
