I've tried to soak my frog once since I've gotten it (only about a month). He absolutely hated it. I'll probably never take him out for a soak again unless I'm worried about impaction or something. I found when he wants in his water, he'll just hop in it.

As far as cleaning, I do exactly what Carlos does. I just coax him into a small critter keeper. I try never to handle him or cause unnecessary stress to the guy. Hes a pretty antisocial guy and doesn't really like my hands being around him. I try to avoid touching him or picking him up at all costs.
