ok i have a small question..i got my red a few weeks ago. he is in a 44x44 with a small bearded dragon. the problem is that the my red is not eating...he is about four or five inches from shell to tail. i have a 150watt bulb about foot or so above him and it's on all night.. i just don't know why he is not eating..I am just getting worried that he is going to die:-( i have had many turtles in the past but this one is causing problems...please help!! thanks, Ryan.
