Hello! I am new here! I just got a baby bearded dragon and want to make sure I have everything perfect! Can someone tell me the best affordable UVB light fixture for a baby in a 40 gallon tank? (Yes I'll upgrade when he gets older/bigger) right now there's calcium sand in there but I've been researching and wondering if I should get rid of that and get substrate carpet/flooring instead? And if someone can just help me list everything I should get for him food wise, tank accessories etc. thank you!
