BLOODFIN TETRA belongs scientifically with Aphyocharax anisiti. In early June, I wrote about Prionobrama filigera, the Glass Bloodfin which is sometimes sold under the name Bloodfin Tetra.

At the time, I mentioned that there are at least two other fish that are sold under the name Bloodfin as well. Aphyocharax anisiti is the one most commonly seen and so it landed a spot in my Monday common fish spotlight.

Can you keep it if you are a beginner?

These are an ideal fish for beginners, living much longer than similarly sized characins. A bloodfin tetra may live up to ten years in captivity.

It is also often recommended for unheated aquaria because it can handle cooler temperatures than most tetras.

The only drawback is that the red pigment that gives the fish its common name tends to fade or become reduced in size when in colder waters.

Most photos you find online will show the fish with pigment in the fins, but the lower half of the belly from behind the vent to the tail can also be red when the fish is warm. Despite this fact, its cold water tolerance is a selling point.

But before you run off to buy a handful to keep your goldfish company, be warned! The common bloodfin is a natural born fin-nipper. Keeping this fish in a shoal of eight or more reduces this tendency, but it does not eliminate the problem.

Bloodfin Tetra Tank and tank mates:

Never keep bloodfins with long-finned fish including angels, fancy guppies, betta, goldfish or gouramis. It is best kept with other tetras, barbs, corydoras, rasboras, platies, and danios. A school of these do not need a lot of room. A 20 gallon, 75 liters, is sufficient.
Origin: Paraguay and Argentina
Size: 5cm /2″
Temperature: 18-28°C/ 64-82°F
Feeding: These fish will greedily eat all foods offered, including flakes.


Bloodfins like a wide open area for swimming with a few areas that are thickly planted for cover. They also appreciate floating plants that shade them from bright lights. They spend most of their time shoaling in the upper third of the aquarium. They also like some degree of water movement.


Like most tetras, they are egg scatterers that give no parental care. Provide clumps of plants as for spawning but also include a layer of glass marbles on the rank floor to prevent the parents from eating the eggs
