Binomial name
Phenacogrammus interruptus

The Congo tetra, Phenacogrammus interruptus, is a freshwater schooling tetra, a type of fish popular in aquariums. They may grow to 4 inches and are suitable for a community aquarium. They are highly gregarious fish and should not be kept in groups of less than 4. The fish will eat high quality flake food and frozen foods such as bloodworms and brine shrimp. A sparsely-planted tank is best, as they like to have plenty of room to swim. They are shy and timid fish, and can be sensitive to water quality, so frequent water changes are a must. Male Congo tetras have longer dorsal and caudal fins and are much brighter and more colorful than the females. Both sexes can be incredibly beautiful with strong lighting and dark substrate. Any aquarium of less than 20 gallons will not be suitable for these fish.
