If you are trying to breed them....good luck.





The body is deep and disc-shaped. The back is orange to brown and the belly is the same. The body color is pinkish violet to orange and in reflected light, purple. The upper half of the iris is red. Just behind the gill cover is a bright red spot from which this fish gets its name. The male's dorsal fin is sickle-shape and black, pink, purple, and white in color. His anal fin is white. The female's dorsal fin is not as elongated, has the same colors. Its anal fin is smaller with less white color. The back is more high-arched with older individuals. the other fins are pink to gray.





SEX: Males are more colorful and have more elaborate fins.


B: Difficult, because females often do not respond to mating attempts of males. Eggs are laid in floating plants and some fall to the bottom. Remove parents after eggs are laid. Fry hatch after 2-3 days and are free-swimming after 2-4 more. The fry are hard to raise and must be kept under a constant regime of regular, partial water changes. Start feeding with small live and crushed dry foods.


BP: 9. A challenging fish to breed.


R: This fish is somewhat susceptible to velvet disease and "Ich". This fish is sensitive to water conditions. Does not usually live more than five years. Requires frequent partial water changes.


DC: 5. The Bleeding Heart Tetra is sensitive to water pollutants and disease. It must be fed a varied diet in order to thrive.
