water tanks of various sizes without water circulation.


1 Larvae: hatched and younger than 1 month, Young: 1–2 months old, Young adult: 2–3 months old, Adult: older than 3 months and sexually matured.
2 In the cases to keep adults to be paired, the numbers of females are presented in parentheses.
3 X→Y indicates how the numbers of fishes will be decreased during their growth. It is noteworthy that the maximum number of fishes mainly depends on the surface area of the tank, not the capacity when the fishes are kept without water circulation.
