Can Keyhole Cichlid Live With Peppered Corydoras?
Yes, keyhole cichlids and peppered corydoras coexist well in a 20-gallon tank with temperatures of 72-78F and a pH of 6.0-7.5.
Why
- Keyhole cichlids are among the most docile cichlids and rarely show aggression toward tankmates, including bottom-dwelling species.
- Peppered corydoras stay on the substrate and sift through sand, avoiding confrontation with any mid-water or upper-level fish.
- Both species thrive in the same temperature range of 72-78F and the same pH window of 6.0-7.5.
- A 20-gallon tank gives the cichlid enough room to claim a territory while the corydoras claim the sandy bottom undisturbed.
What could go wrong
During spawning, keyhole cichlids may become slightly territorial and guard their eggs, but they rarely chase corydoras because the catfish stay too low to be seen as a threat.
