The African Red Eye Tetra is a very active, larger characin that is an excellent choice for the larger community aquarium!
The African Red Eye Tetra (Arnoldichthys spilopterus) is a fairly popular African characin that is extremely active and perfect for a community aquarium of medium and large fish such as Kribensis and Jewel Cichlids, Synodontis catfish, and other African tetras. It has an overall silver body, but develops very noticeable iridescent blue, green, and yellow coloration as it matures.
The African Red Eye Tetra typically occupies the top and middle level of the water column, although it can often be seen swimming and feeding in the middle and bottom levels as well. It is safe to keep with other peaceful fish that will not be intimidated by the constant activity of the African Red Eye Tetra. Though it has a relatively robust, larger body than many smaller tetras, it has a very small mouth. It is not a good tankmate for dwarf shrimp, but it could be kept with larger, peaceful invertebrates too large to be considered prey. The African Red Eye Tetra often inhabits blackwater habitats, but is somewhat adaptable to a variety of pH levels. It is sensitive to poor water quality and will not thrive in an aquarium where regular maintenance is not performed. This species has not likely been bred on a major level, but there are many hobbyist reports of the African Red Eye Tetra breeding in the home aquarium.
While not generally a picky eater, the African Red Eye Tetra is sometimes finicky about accepting dry foods when first introduced to the aquarium, so it should first be offered live or frozen foods with high protein content. It will thrive and remain very colorful on a varied diet of foods and will usually learn to eagerly accept dry foods as part of its feeding regimen.
