Can Cockatoo cichlid Live With Cardinal tetra?

Detailed assessment

Both Cockatoo cichlid and Cardinal tetra share a comfortable temperature range of 23.9–28.9°C (Cockatoo cichlid prefers 22–29°C, Cardinal tetra prefers 23.9–28.9°C). Their pH ranges overlap well at 6–6, so water chemistry is compatible. Both species have low aggression scores (Cockatoo cichlid: 2, Cardinal tetra: 1 out of 10), which supports peaceful cohabitation. They occupy different water columns (Cockatoo cichlid: bottom, Cardinal tetra: middle), which reduces direct competition for space. Note: species with non-overlapping ph ranges may not thrive together With careful monitoring and adequate tank size these species can usually coexist, but be prepared to separate them if aggression or stress appears.
