Southern Toad/American Toads hibernating or sick?

[kueluck]

I have Fowlers, Southern & American together in a 40 gallon breeder tank. They have 4 to 6 inch of organic soil mixed with eco earth, topped with leaves and moss to help hold some moisture in the soil. Some of them will stay underground for several months at a time, others several weeks. When they are ready, they come up to soak, eat and then go back underground until spring. I change the water every day and put fresh roaches in just in case someone shows up. They also prefer temps 62 to 76 (cooler temps at night), I would be afraid the UTH would dry out the substrate and make the tank to hot. I'm no expert, but this is what works for me and my toads. Once they go underground they do move around, so I keep one end a little moister than the other one.

If you don't them to dig so much fill that tank with wooden hides, logs they can semi burry under, plants. Toads love to dig to feel safe and if there isn't anything for them to dig under they will most often fully bury under the substrate.
