The safest substrate is Eco earth coco fiber (not the husk). Expand and moisten it in dechlorinated water or spring water. Change his substrate ever 4 to 6 weeks. Remove any feces as soon as you see it. Also, change his water bowl water daily.

They stress easily. To help reduce stress, get him something to hide under. A plant or log hollow works well. They have them at the pet store. Another thing to do is to cover the back and 2 sides of his tank with a medium or dark background. Outdoor colors work best. You can do this in several ways.

Lighting...they need a 12 hour day light cycle. This means 12 hours of night, 12 hours of day. They do not like bright light. They are nocturnal, so they must have 12 hours of dark. Very important. A simple low watt bulb can be used. You do not need anything fancy.

Oh, I forgot to tell you, you'll need an amphibian multivitamin powder. Lightly dust his food one day a week with the vitamin. When your frog is healthy again, lightly dust his food every other day with the calcium with vitamin D powder. Do not feed him mealworms, they cause constipation. The best staple foods are cut up earth worms or night crawlers, crickets, and roaches. Their food should be no larger than the width between his eyes. Feed him as much as he wants in 15 minutes daily. Be sure the worms have no dyes or scents added to them.
