Bloodfin Tetra | Tim's Tropical Fish


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 is a shoaling fish and you should therefore keep at least five specimens together. When a Bloodfin tetra is kept alone, or in a very small group, it will usually become very shy and spend most of its time hiding. In a shoal, they are much more bold and active and spend a lot of time out in the open. A Bloodfin tetra can sometimes leave the group and explore the aquarium on its own, but it will always return to the safety of the group as soon as it feels threatened.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.Bloodfin tetras will often spawn spontaneously without any coaxing from the aquarist. Their natural instinct is to release the eggs among broad-leaved plants, but if no such plants are present they will sometimes release the eggs over aquarium glass. The eggs are not adhesive.
During the spawning, the Bloodfin tetra will leap out of the water and the eggs will drop down. One female will usually produce between 300 and 500 eggs during each spawning.

Since it is an egg-shattering species that do not engage in parental care, it will not hesitate to eat its own offspring. A lot of eggs and fry will therefore be eaten by the parents, or by other fish in the aquarium. You can increase the chance of fry survival by keeping the aquarium densely planted. Do not only use broad leafed plants in your Bloodfin tetra aquarium; include fine-leaved species as well since they provide better protection. You can also spread beads over the substrate to create hiding spots for eggs and fry. Professional Bloodfin tetra breeders usually set up separate breeding aquariums from which the adult fish is removed directly after spawning. This will promote a much higher fry survival rate.
