Hello and welcome to FF! Frogs and toads do absorb their water and chemicals through skin so it's important it has no chemicals that could harm them. Tap water treated with a dechlorinator (Seachem Prime or ExoTerra Aquatize are good) is fine. If a soaking dish it should be cleaned and refilled daily. Do not use distilled, R/O, de-ionized or any purified water that could cause minerals to move out of frog into water.

Your temps are OK (keep between 73-82F with slight drop at night). Substrate can be unfertilized top soil (no chemicals) or shredded coco (Plantation Soil or EcoEarth) mixed with dechlorinated water so it's slightly damp (clumps in fist but does not drip water out). Spot clean daily and replace it once a month.

Toads eat many things, young ones can be fed daily; just remember to size insects same a distance between it's eyes and earthworms as long as toad is. BTW, how long is your toad from snout to vent (SVL) and how large is it's enclosure? If young it's food should be dusted with CA/D3 2X and vitamins 1X on different days with skip day in between. Once full grown can feed couple times a week and reduce supplemental dustings too. Have you tried offering undyed night crawlers (Walmarts sports section or bait shops)? They are very nutritious and most toad and land frogs will eat them.

Maybe it will help if it has more than one hide hole. You can use a new plastic pot cut in 1/2 and placed on ground or a slab of cork bark angled against a corner to provide another hideout. Please post a pic of your toad and enclosure to get a better idea of set-up. Thanks and good luck !
