Said to be sensitive to poor water conditions the bleeding heart can be a great member of a community. The tank should be well planted either using live or plastic plants and be dimmed with some floating material. They are more sensitive to light than most so an arraignment of dark colors is better. A shy fish you will need to provide hiding places but also leave open spaces for swimming. Feeding is not a problem as they will except all types of food, flake frozen or live, what is important is that you vary the food on a regular basis. Kept in groups of six or more and away from any fin nipping species the bleeding heart should b provide you with many hours of enjoyment.
Although it has been reported, this fish is a challenge as all conditions have to be perfect. Isolate and condition the male in a tank containing many fine leafed plants such as Myriophyllum, Cabomba and some Java moss, also include some floating material as well. After a few days introduce the female to the tank. After the mating ritual the eggs are scattered among the plants. Remove parents after eggs are laid. Fry hatch after 2-3 days and are free-swimming after a few more. They must be fed the finest of foods like baby brine and crushed flake.
