These cool fish are known as Columbian tetras. They will grow out to about 3 inches in length as adults. As they age, they will develop blue marking on their body along with bright red fins. They are schooling fish so it is recommended to keep them in groups of 6 or more. They are hardy fish that do well in community tanks! Some good tank mates include Silver Hatchets, Zebra Danios, or Corydoras. They are carnivores so a diet can consist of bloodworms or pellets.
