As some of you know my Fowlers toad Rufus passed away this week of unknown causes. For the past 3 years I've always kept up to 5 inch of substrate for them to burrow in. Last year I had 2 females burrow for 7 months with no ill effects but I'm wondering if I really need to have it this deep, if maybe I had kept the levels lower so they couldn't burrow that deep Rufus may still be around. Just looking to see what others are doing. I was going to dig up the other 4 but I'm concerned this would put to much stress on them.
