They are both in the same tank (90cm x50cm x115cm tall) I have the desert blend (that the vet told me to get), dragon loves to hide and borrow in it, bell loves to basking. I feed them URS complete balance diet for juvenile bearded dragons plus crickets and silverbeat, cucumber, carrots everyday. They have a medium size water dish that is very shallow. Temp range from 24*C and 37*C.
