Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to care for a white's tree frog [title] Buy a large aquarium. [step] The tank should be at least 20-gallons. The taller the better, as white's tree frogs love to climb and to perch themselves high on branches.

Ending1: [title] Fill the tank with a saltwater mixture. [step] White tree frogs love saltwater, and it's recommended that you use aquarium water that's at least 80 gallons. Ending2: The size of the tank depends on the species of frog and its size, so make sure it is large enough for a white tree frog. If the frog is larger, do not keep it in a black hole. Ending3: You can also buy small aquariums and a ten gallon aquarium and set them in the same inner space of the tank. As with most species of frog, white's tree frogs get too warm, so they like a cooler place to rest at night for healthy plants. Ending4: You can purchase a tank at a local pet store or online through a company like exo terra. [substeps] Arboreal and terrestrial tanks are your two best bets.
