Can Blue Emperor Tetra Live With Endler's Livebearer?
Yes, blue emperor tetras and endlers share a tank well in 20 gallons or larger since both species are peaceful and occupy different water levels.
Why
- Blue emperor tetras grow to 1.5-2 inches and swim in the middle water column.
- Endlers grow to 1-1.8 inches and prefer the top water column, so they do not compete for the same swimming zone.
- Both species tolerate temperatures of 73-81°F without stress.
- Both species are peaceful and too small to bother each other.
- Both species feed on the same flake and micropellet foods, so feeding is simple with no competition.
What could go wrong
Endlers may interbreed with guppies if they share a tank, but blue emperor tetras are not guppies, so hybridization is not a concern here.
