New Fish Tank Tips: Get and use an aquarium water test kit to monitor the aquarium nitrogen cycle. The best way to monitor this cycle is to purchase a freshwater or saltwater test kit that will test for ammonia, nitrites, nitrates and ph. Test the water coming out of your tap as well. This will arm you with more information when it comes time for those water changes.

The Bloodfin Tetra is a type of tropical fish. Bloodfins are comparatively large tetras, growing to 5.5 cm. Its notable feature (as the name suggest) is the blood red colouration at the tail, dorsal, anal and adipose fin.
Bloodfin Tetras are best kept in schools of 3 or more.
They swim mainly in the upper and middle water layers and are highly sociable fishes, mixing well with other types of tetra and tropical fish in general, so are therefore ideally suited (like many other Tetras) to a community tank. Although, like most tetras, they will tend to nip at the fins of fish with long, wavy fins such as an angelfish or guppy.
An extremely hardy tropical fish well suited to beginners, bloodfin tetras can also be kept in cold-water tanks, providing the temperature does not drop below room temperature. They thrive quite happily in temperatures ranging from 64 – 83 degrees Fahrenheit.
Turning on and off aquarium lights tends to blind these fish and cause them to dart around frantically, but they will settle down shortly after.
