I have 4 adult corns that use to eat like champs but havnt eaten in about 3 months. I thought they were just fasting but 1 of them died yesterday. They are all in seperate 30 gal tanks that are 78 deg on cool side and 88 deg on side with the uth. They use to eat 2 adult mice per week but all of them suddenly stopped. I have a rat snake in the same room that has kept his same eating habbits. Please help. I dont want to loose any more of my pets!
