My male that's probably 2 years of age and is 1200 grams pushes on his tub like CRAZY day and night. He is always on the cool side of his tub trying to get out. He doesn't like to eat.. probably takes something small every three weeks. He went off feed for about 3 months (I attributed that to the 1k wall and I'm pretty sure he wants to get out looking for a female). He is starting to get a bump on his nose and I'm concerned about him. How can I stop his pushing?
