Possible, with care

• Pea puffer Pea puffers are aggressive, though congo tetras are big enough to shrug most of it off.
• Bamboo shrimp Congo tetras will eat baby shrimp and may chase adults. Dense plants or moss give bamboo shrimp somewhere to hide.
• Cherry shrimp Congo tetras will eat baby shrimp and may chase adults. Dense plants or moss give cherry shrimp somewhere to hide.
• African dwarf frog African dwarf frogs eat slowly and nearly blind. Fast congo tetras will take the food first, so target-feed them.
• Amano shrimp Congo tetras will eat baby shrimp and may chase adults. Dense plants or moss give amano shrimp somewhere to hide.
• Ghost shrimp Congo tetras will eat baby shrimp and may chase adults. Dense plants or moss give ghost shrimp somewhere to hide.
• Common pleco Plecos grow to 15 inches and need 125 gallons, far more than a tank set up for congo tetras.
• Bala shark A grown bala shark may treat small congo tetras as food, especially at night.
• Molly Water chemistry is a squeeze. The only pH that suits both is around 7.5.
• Koi At 24 inches a koi can swallow a small congo tetra. Fast, alert fish usually stay out of reach.
• Electric yellow cichlid Different water: congo tetras want pH 6–7.5, yellow labs want pH 7.8–8.6.
• Tinfoil barb A grown tinfoil barb may treat small congo tetras as food, especially at night.
• Discus They only share 82°F. Keep the heater set there and steady.
• Peacock cichlid Different water: congo tetras want pH 6–7.5, peacock cichlids want pH 7.8–8.6.
