my guy has been alot more active & 'chillin' on top of his hide, rather than in it. I have 2 UTH's on either side of my 20L tank & was having trouble with my ambient temp being too low, so I obtained a CHE. What is more important, belly heat or top heat? Is he just really enjoying this new basking spot? I've been having quite a hard time getting the temp & humidity just right, it seems like a constant, never ending battle
