K. If he is pooping regularly in his dish no need to soak him. Also you only need to clean his tank once a month to every three weeks. Keep working on the nightcralwers. They are the best staple food. I use a mix of worms crickets and dubias, bust mostly worms. You need to calcium dust twice a week and vitamin dust once a week with at least a day in between. Make sure that all water you use is dechlorinated, if not you will kill your frog. The tank might be too big for the little guy and might stress him out. If he stops eating all of a sudden that might be why. What wattage light bulb are you using make sure nothing over 50 watts should be used. I'm not going to do the Celsius to Fahrenheit conversion but day time temps should be 82-84 degrees and night time temps should be 77-78 degrees. They do need a day and night cycle. I use day and night bulbs with no uvb/uva both are 40 watts. Also remove that moss ASAP. It will cause impaction and will hurt the frog. Also the live plants probably won't make it when the frog is full grown frog produce a lot more waste than the plants can break down. These types of frogs like it simple. Eco earth, water dish, and a couple small hiding areas (plants or what not)
