Hello everybody, this is my first post on this site. I have a 14 inch male (I think) bearded dragon who has been living in a 20 gallon tank with reptile carpet. I want to switch him to a different substrate because the reptile carpet isn’t working out and won’t fit in his new tank (~25 gallons). I am thinking about using either sand or tile. I got some quikrete playsand, sifted through it, and washed it, but I am still not sure if that is the best way to go. I am also considering tile and having a sandbox for about 1/3 of his tank for him to dig in. Advice? Any replies are helpful. Thanks!
