Zebra danio minimum tank size

Zebra danios need at least 81 L (21 US gal), in a tank at least 90 cm (35 in) long.

That is the largest minimum among the sources below. The planner also checks the tank length against the adult size of 5 cm (2 in): a tank shorter than 4 times that is cramped (20 cm (7.9 in)).

• BettaBettas need 24.4–29.4 °C (76–85 °F); zebra danios need 18–24 °C (64–75 °F). No temperature suits both. Bettas are usually best kept alone. Some accept calm tank mates such as zebra danios, many do not.
