I'm watching my neighbor's daughters' African dwarf frogs until Monday (the same neighbors whose sick bettas I watched a while ago). They just dropped off two 6-inch plastic cubes of water, each containing an inch or two of gravel, a bamboo plant, and two frogs. Now, I've never kept frogs myself, but I'm pretty sure they have similar requirements as bettas. I want to do my best for these frogs, and I feel bad leaving them in the little cubes. Right now I have an empty, uncycled 10g tank with a heater but not a filter, and I can set up a 4g bucket with a heater and a filter. Would it be best to move the frogs to either of these, or leave them where they are? (I can divide the 10g if it helps) Also, they said they planned on cleaning the tanks in January. I'm guessing they're doing a full water change every few months. Should I do daily water changes, or just one, or none? Any advice is appreciated.
