Hi! You can put him into a 10 gallon tank for now with a screened lid.

Here is what I found...

Provide a shallow water dish with shallow spring water or dechlorinated water in the dish. Change the water daily.

How big is he? If he is 1" or less I'd feed him flightless fruit flies. If he is larger you can do pinhead sized crickets. His food should be no larger than the distance between his eyes for easy swallowing.

Cover the back and 2 sides of the tank with a background of some type to make him feel safe.

You can use paper towels for substrate to line the floor with. Mist the tank with a sprayer 2x/day.

If you can add a soft, smooth-edged fake plant or a real plant with all fertilizers and pesticides completely rinsed off and then replanted in Eco earth, he would like that.
