Check adult requirements

Record the baseline and check social group and pressure on females. Do not infer the aquarium's condition from a single sign. Confirm scientific identity, adult size, diet, social behaviour and swimming zone.

Then compare stable water with suitable hardness 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 continuous reproduction and aquarium capacity before continuing. Keep a reference so the result can be compared. Plan the complete group and monitor feeding, breathing, injury, shelter and space use.

Do not underestimate future load because the adults look small.
