Hello all, I have an adult male pastel that is almost 7 years old and he has gone off food for almost 6 months now. He normally only eats live, but he will just defensive strike at them, but will not wrap and kill. I have offered a live rat to him once a week with no luck. Good thing my female will eat three mediums or i would be out some money. i have been watching to see if maybe he some respiratory issue goin on, but no bubbles or excessive yawning. The person i got him from suggested that i move him from the 55 gallon tank i had him in to a sweater tub, which i did about 6 months ago, but he still will not eat. At what point do i get seriously concerned and take him to a vet. He doesn't seem to have lost any weight, but he has gotten pretty pissy and doesn't like to be handled. He didn't shed good the last time as well and still has a hue to his eyes. Please help.
