oh that's not good!
Chams shouldn't be kept in anything except a screen cage. They need really good ventilation. A water bowl won't work for a cham as well, their enclosure needs to be missed with a spray bottle at least twice a day for 2-3 mins at least! They don't drink out of standing water bowls and the bowls get too dirty too quick. And that cham needs a UVB blub, and a heat lamp. There's a million other things wrong with this too.

See if you can point him in the right direction. I know it's hard, but that little cham is in for a rough time if he doesn't wise up. They're not difficult to keep as long as he meets ALL of their care requirements. If he doesn't there's lots of things that can go wrong.

And the absolute worst part is it's your gf's dad, so you have to be nice about it! Good luck, I hope you can help the little guy.
