Can Electric Blue Acara Live With Sterbai Corydoras?
Yes, Electric Blue Acaras and Sterbai Corydoras do well together because both species prefer calm tanks with soft substrate and overlapping water parameters.
Why
- Electric Blue Acaras stay relatively peaceful at 5-6 inches, leaving corydoras unmolested in most setups.
- Sterbai Corydoras occupy the bottom level while Electric Blue Acaras stay in the mid-to-upper water column, so they occupy different zones.
- Both species tolerate the same temperature range of 75-82F and pH of 6.0-7.5 without stress.
- Corydoras are social and should be kept in groups of 6 or more, which Electric Blue Acaras ignore entirely.
What could go wrong
Overstocking the bottom level with too many corydoras can cause competition for hiding spots if the acara feels territorial.
