Can Buenos Aires Tetra Live With Kribensis?
Yes, Buenos Aires tetras and kribenses share a tank well in 30 gallons or larger since both are active species that tolerate the same water parameters.
Why
- Buenos Aires tetras grow to 2-3 inches and swim in the middle water column.
- Kribenses grow to 3-4 inches and stay near the bottom, so they use different swimming zones.
- Both species tolerate temperatures of 75-82°F without stress.
- Both species thrive in pH 6.0-7.5, which gives a clean overlap for shared water.
- Buenos Aires tetras are large enough and fast enough to avoid kribensis territorial behavior.
What could go wrong
Kribenses become territorial during breeding and may chase bottom-dwellers away from their cave. In a 30-gallon tank with hiding spots, Buenos Aires tetras have enough space to stay out of the way.
