Food and feeding
Blood fin tetras are omnivore and in their natural habitat feed on crustaceans, and insect larvae. In the aquarium they should be offered a staple diet of flake and small pellet foods, with the addition of live foods 2-3 times per week. They are very fond of blood worm and brine shrimp.
The blood fin tetra originates from South America, namely Brazil, Paraquay, and all the way to Argentina.
Males tend to be more colorful than the females; they also have a more hooked shaped anal fin. The females will have a much plumper body shape than the males.
This species of fish are extremely easy to breed, often they will just pair up and breed without the keeper even noticing, if they are in a community tank. To set up a breeding tank, add lots of broad leaved plants for the eggs to disperse into. The female will literally jump out of the water to scatter the eggs around the tank. They have no parental skills whatsoever, so if the fry are to be saved remove the parents or they will definitely remove them. Laying glass beads on the substrate will also allow the eggs to lay underneath for protection.
Blood fin tetras, if cared for properly can live for up to 10 years.
Aphyocharax alburnus should be kept if groups of at least 6 fish as they are a natural shoaling fish, if kept singly they will become shy and will hide a lot. They are easy to keep but water conditions must be good, being peaceful fish they make a great addition to a community set up.
