About the Bloodfin Tetra
Species Type: Freshwater Fish
Care Level: Very Easy. Will tolerate a wide range of water parameters including pH, temperature and hardness. Can tolerate higher nitrate levels than other fish and is hardy enough to withstand the cycling process. Will readily eat prepared foods and has no special care requirements.
Origin: Rio Parana basin in Argentina, Brazil and Paraguay, South America. Inhabits streams and rivers shaded by floating and overhanging vegetation.
Compatibility/Temperament: Very peaceful, must be kept in a group of six or more. Good companion for peaceful fish sharing similar water parameter requirements such as livebearers (basic/hard) or other characins (soft, acidic) and small catfish and loaches. Not good with long-fin fish as it may then nip at the fins.
Although tolerant of cooler temperatures than most tropical aquaria, the colours will be their brightest in aquaria maintained at the normal tropical fish temperatures. This species prefers to swim in the upper half of the aquarium, and may jump occasionally, so the aquarium should be covered.
A hardy and adaptable fish, it has been known to live more than 10 years in captivity. Males have a small hook on the anal fin and are a bit more colourful than females.
This species appears under several common names including Glass Bloodfin, Red-fin Tetra, etc. Scientifically, the names originally assigned to fish believed to be different species, namely Aphyocharax affinis, A. ipacarayensis, A. rubropinnis and Phoxinopsis typicus, are now determined to be synonyms of A. anisitsi [Eigenmann & Kennedy 1903].
