my son got this beardie from a guy he knows. well it looks horrible..looks malnurished. its lower jaw seems to extend out more than the top jaw and its tongue is always hanging out. when i give it water it drinks but its tongue looks very large compared to the beardie i have. it runs around but looks so thin, we found out that all it has been eating when this guy had it was lettuce and fruits..no worms or crickets. please anyone tell me what i need to do and why does its tongue look so large and what is the deal with its jaw..is that normal. i need lots of help and info.
