Leucistic Southern Toad found.

[Psychotic]

He is very rare. I've seen pictures of other toads like him. But not very many. Awesome find! You are very lucky. I would love to have a leucistic or albino toad.

Your set up sounds good. Toads like it dry. But they also like to sit in their water dishes sometimes. Room temp is fine. No special lights are needed.

I wouldn't recommend feeding mealworms though. They can cause impaction. If anything you can feed him crickets and/or roaches. Don't feed him anything bigger than the space between his eyes. Most toads also like chopped up earthworms if they can figure out how to eat them.

As to how much. Let him eat as much as he wants in a 15 minute sitting. I would only feed him every 3 days or so. You can also dust with calcium d3 once a week (phosphorus free). Some people also use a multivitamin too (though you can't use it at the same time as the calcium). Personally I don't dust at all. I gutload my feeders by feeding them a varied diet (fruits and veggies) and I feed calci-worms.
