Check adult requirements
Record the baseline and check lake or drainage origin, hardness and pH. Do not infer the aquarium's condition from a single sign. Confirm scientific identity, adult size, diet, social behaviour and swimming zone.
Then compare breeding behaviour and territorial structure with livestock needs and recent changes. Look for genuine overlap in water, flow, territory and feeding throughout the year.
Assess compatibility and welfare
Adjust one variable and assess adult size, diet and functional hardscape before continuing. Keep a reference so the result can be compared. Plan the complete group and monitor feeding, breathing, injury, shelter and space use.
Continental labels are too broad to decide compatibility.
