The Colombian Tetra (Hyphessobrycon columbianus) is an attractive, moderately-sized tetra from South America. Their scales have a bright blue lustre and their fins are red.
These tetra grow slightly larger than most other readily available tetra species, reaching up to 2.5" in length. These fish are shoaling and should be kept in groups of at least 5. A 10-gallon aquarium is recommended as a minimum tank size for this species. The Colombian Tetra requires a water temperature between 75-80 degrees Fahrenheit, and a pH between 6.0 and 7.0.
These fish are not particularly picky and will eat most foods offered. It is recommended to alternate between multiple types of foods for best results (such as flakes, pellets, and frozen foods).
The Colombian Tetra can be semi-aggressive and is known to occasionally pick on smaller tankmates or tankmates with long fins. These tetras do best with another similarly sized tetra. Keeping these fish in large groups will reduce aggression.
