Bronze corydoras minimum tank size

Bronze corydoras need at least 114 L (30 US gal), in a tank at least 80 cm (31 in) long.

That is the largest minimum among the sources below. The planner also checks the tank length against the adult size of 7.5 cm (3 in): a tank shorter than 4 times that is cramped (30 cm (12 in)).
