The red eye tetra adds a touch of glamour to a freshwater community aquarium. Their metallic look, dynamic energy, and signature red eye with its pop of color combine to create an elegant display when kept in a school of six or more. This fish is a good choice as a beginner fish. Water conditions fluctuate much in its natural habitat, so this fish can tolerate a wide range of differences and changes. The red eye tetra is a relatively larger tetra and should ideally be housed in a 20-gallon or larger aquarium.

Best tank mates for the Congo Tetra

Tankmates can consist of the majority of small african and South American Characin fishes, live-bearing fishes and barb (except, maybe the tiger barb), corydoras (like pygmy or panda), dwarf cichlids like ram cichlid. However, still it’s more proper to keep congo tetras in a school of 4-20 species separately from other fishes.


In nature, fish eat whenever they are hungry and the food is available. If food sources are plentiful, they will eat several times a day. On the other hand, if food sources are scarce, they might go for days between meals. For this reason, fish are very opportunistic and will eat whenever they have a chance.

Regardless of one or two feedings, the key is to keep each feeding very small. Do Not overfeed your fish. Whenever in doubt, the best practice is to underfeed your fish. There are a lot of health concerns related to overfeeding your fish.
