Can Celestial Pearl Danio Live With Ember Tetra?
Yes, celestial pearl danios and ember tetras coexist well in 10 gallons or larger, and both species prefer planted tanks with soft, slightly acidic water.
Why
- Both species reach about 1 inch, so neither will prey on the other.
- Temperature overlap of 73-79°F and pH 6.5-7 is ideal for both species.
- Both are peaceful schooling fish that do best in groups of 6 or more.
- Celestial pearl danios are mid-water swimmers while ember tetras tend toward the lower-mid water column, giving them spatial separation in the tank.
What could go wrong
Both species are sensitive to ammonia spikes. A new tank cycle will stress both if water quality is not fully established before introduction.
