The Bloodfin Tetra is a mainstay of the freshwater fish hobby and for good reason. Bloodfin Tetra have silver bodies with an almost greenish hue (depending on the aquarium lighting) and red fins. A great freshwater beginner’s fish, the Bloodfin Tetra will to tolerate a wide range of water parameters. Some hobbyists even keep them in cold water tanks or tanks without heaters. They will tolerate a lower temperature than other tropical fish, but use a heater to keep the temperature stable. Avoid widely fluctuating water temperatures that could stress your fish.
The Bloodfin Tetra can get a little skittish at times. Keeping them in a school of 6 or more should limit this behavior and a larger tank with lots of open swimming space will help prevent them from getting injured. They are quite active and should bring lots of activity to a community tank or a tetra tank setup scheme. You may see them nipping at each other from time to time and this is normal behavior amongst the school. It should not be a cause for concern unless it seems to be getting out of hand.
The Bloodfin Tetra is another fish that isn’t too picky about what it eats. A good quality flake should form the main part of their diet with supplemental feeding of brine shrimp (live or dried), frozen freshwater foods and live foods such as worms or small insects.
