I have two whites tree frogs. recently, one has stopped eating all together. when ever food is placed neer her, she actively backs away from it. she also seems to be sitting with a gaping mouth for long periods at a time. i have seperated her from the other one (who is totally fine). her temperature stays at a steady 28-29 degrees, has regular calcium supliments, water is changed daily and the tank is cleaned one a week. apart from not eating (she has lost a lot of weight) and having this 'gapin' mouth, she seems fine, and becomes relatively active at night. plz help!!!
