Can Apistogramma Live With Peppered Corydoras?
Yes, apistogrammas and peppered corydoras share a 20-gallon tank well, with matching parameters and non-overlapping bottom zones.
Why
- Apistogrammas are dwarf cichlids that stay at 2-3 inches and occupy the lower-to-mid levels, while corydoras stay on the substrate, so territorial overlap stays minimal.
- Temperature overlap of 72-79F suits both species comfortably without compromise.
- pH range of 6-7 is ideal for peppered corydoras and acceptable for most apistogramma species, keeping water chemistry simple.
- Corydoras are peaceful bottom dwellers that pose no threat to apistogrammas, and their armored bodies resist any minor aggression from the cichlids.
- A 20-gallon tank gives enough horizontal space for apistogramma pairs to establish territories while corydoras school along the substrate.
What could go wrong
During breeding, apistogrammas may defend their territory more aggressively and could stress corydoras if the tank is too small or lacks hiding spots.
