Bloodfin Tetra

Author : Efrain Silva


Bloodfin Tetras have bright red fins (the color of blood), hence the name they were given. These guys are one of the largest Tetras around, standing at appx. 5.5 in cm. Its dorsal, fins and tail are all equally bright with the redness (must look nice in the water during Christmas time, hehe).

Its main body is a beautiful silver color, complementing the red nicely — a good touch, I’d say, all in all. It typically has the usual white eyeballs and black pupils that most other fish of its class do, so nothing new there….


The diet of this carnivore will consist of shrimp, daphnia, tubifex, blood worms, micro pellets, protein flakes — it’s all good, and this fish will thank you for whatever you would be happy to provide.

You can try these foods in either dried or frozen varieties, as well, giving you more options to select from when feeding ; the more, the merrier, as they say, right? This fish can also consume some plants and a few vegetables, from time to time, in order to keep its diet fully optimally - balanced, all in all. These ‘additional carnivore’ type foods are optional.


The origins of it? Well, it all started out with a name of Aphyocharax anisitsi as its scientific classifier ; and people everywhere have now had a chance to further read about and study this unique creature, known by such a long and complex technical term name.

This fish is a part of the characin species and will not let you forget it, displaying countless similar features and characteristics of this special breed. For more on that, simply Google the term ‘characin fish’, and read on to your heart’s content! The Bloodfin Tetra is found amongst many water canals throughout South America, notably spotted often around the Paraná River basin as well.

Roommate Situation

Would you like a roommate for it, or perhaps two or more? We are glad you have chosen to consider the social needs of this fish, but before you do so, hear what I have to say. First of all, the Bloodfin Tetra is perhaps another like - minded fish or group of fish, who enjoys peace and calm.

The Bloodfin Tetra is quite peaceful, and a community tank, in this case, may be a great idea. If the other fish are much larger than it, however — beware — they may try to eat it for lunch, so try to keep same - sized fish together at all times.

Other Facts to Note

Another good point should be taken into consideration as well, and that is the fact that this fish can also get a bit ‘nippy’ when it comes to other fish like guppies or angelfish.

It may go for their fins if they are smaller than it – don’t mean to scare you here, but that is just something for you to briefly keep in mind before proceeding with the purchase. And speaking of which, if you liked this article, then run to the store and get your Bloodfin Tetra now!
