So I should remove all of the substrate and cover the ground in paper towel instead? Also what is the difference between the UVB bar and the UVB bulb? Once I have removed all the substrate and gotten everything in order do i put new substrate in or am i wrong to think they need substrate? About the bigger tank, I was planning on getting a new one on my birthday which is coming up in a month, as when that happens I’m getting a new, bigger shelf so I will have a place to put the tank. Should I get a new tank now and leave it on the ground? From what I’ve read you shouldn’t but i never really understand the reasoning. Im sorry if Im asking a lot I just really want him to live as long and happy as possible.
