Quick update: the toads are now moved in at college. The temp in their enclosure is usually around 75 degrees (the average temp of my room is 72 degrees, i don't fully control it). Humidity still around 50-70%, depending on how recently I've misted.

The toads spend most of their time hanging out together in their big water tub, sometimes just sitting on each other. Should they be doing that, or are they being weird somehow?

One of them eats regularly, around 3 or 4 superworms a day. The other 2 stubbornly ignore any food, which is crickets, dubias, or superworms.

The one that eats feels pleasantly firm when I pick him up, and he is very vocal about being upset that I pick him up. The other two are pretty squishy. They don't feel too skinny, but very squishy around the belly.
