The breeding part in the bleeding heart tetra care routine for this fish can be difficult to deal with, but this isn't impossible and can be done under proper water conditions in a community tank or aquarium. The female fish often ignore the male fish if kept in the same tank. Thus, a separate breeding tank is placed so that both male and female bleeding heart tetra fish can breed properly. Either you should pick the best pair or let the female fish decide accordingly. For proper mating, a 20 gal tank (76 l) is important. A female's belly becomes big and nicely rounded when she has lots of eggs. The tank should not have hardy water, and different plants should be there in the tank so that the females can lay eggs properly as the females need a proper place to lay their eggs. After the females lay the egg, you should keep the tank or aquarium quite dim as the eggs cannot tolerate much light. The water must be soft and with a proper acidic level. Males and females should both be removed from the tank when the eggs settle at the bottom, or they might eat their eggs. Eggs generally hatch within two to three days. In three to four days, they start swimming. In the initial days, the fry must be fed with infusoria-type foods. The diet of the fry is important for their survival and lifespan.
