Can Congo Tetra Live With Peppered Corydoras?
Yes, Congo tetras and peppered corydoras coexist well in 30 gallons or larger because Congo tetras swim in the upper levels while corydoras stay on the substrate.
Why
- Congo tetras occupy the middle to upper water column while peppered corydoras stay on the bottom, so they use different tank zones.
- Temperature overlap of 73-79°F covers a wide range that suits both species comfortably.
- pH range of 6.0-7.5 covers slightly acidic to neutral water, matching the soft water preferences of both species.
- Peppered corydoras are peaceful bottom dwellers that pose no threat to the more colorful Congo tetras.
- Both species are schooling fish that do better in groups of 5 or more.
What could go wrong
Congo tetras may outcompete corydoras for food since they eat from the surface and mid-level. Drop sinking pellets for the corydoras so they get their share.
