Congo Tetra are amazing additions to community aquariums. We recommend at least 30 gallons or more for them since they grow to be about 3-3.5 inches. They are schooling fish and do best in groups of at least 6. Keep their water between 74-82°F and provide a lot of plants for coverage and foraging. If you want to keep other fish besides just more Congo tetras with them, choose peaceful, calm fish. All pictures shown are for illustration purposes only. Actual products may vary due to natural variation with livestock.
