Redfoot like a dim light over them. They do not like bright lights.
If you go into Petco and ask about UVB bulbs, you will buy the wrong bulb. Not only will you be out the money, but the bulb could burn your tort's eyes and blind him.
You need to first read the care sheets very carefully to learn what to buy. The people at Petco do not know what they are talking about and will tell you all wrong stuff. Then you won't have money to buy the right stuff.
Do you have the lid for that bin? If not, you need to buy a different bin with a lid. You must get the biggest bin you can find, both long and deep.
Don't buy anything until other members come on and tell you exactly what to get.
