New dart frog hobbyist here!

Hi! My knowledge of dart frogs is limited, but many people keep a single frog in a 10 gallon tank. In a larger tank one per 10 gallons(37 liters roughly).
Humidity is generally kept around 80 or 90 to 100, while temp is 75-82°f (sorry for no Celsius).
Also, dart frogs of different species should not be mixed. Only one species should be housed in a tank. For this reason, some dartfrog hobbyists prefer many smaller tanks rather than larger ones. I hope this helps!
