I have a 20 gallon gallon (76 liters) long tank with a lid to keep my african dwarf frogs in. I'd like to eventually move them to a bigger tank without a lid.
Considering the maximum water height for the frogs are about 12 inches inches (30 cm), and I'd like 2 - 3 inches inches (5 - 7.5 cm) of substrate for plants, that would require a minimum of 15 inches inches (38 cm) of height, plus however high they can jump, plus a few inches for good measure. The problem is I haven't been able to find any data on how high they can jump from the water.
