About a month ago, I got my very first snake, Java, and id say he's about four months old. His skin has been really dull for about half that time and about a week ago, his eyes started to cloud over. I am super worried because its still only the top that are clouded, and his belly has been slightly pink almost the entire time that I've own him. I'm super worried and dont know what to do! He's about 16 inches, eats a small adult mouse every week without problem. He's in a 20 gallon tank, hide box, water, logs to climb on, and the temp is around 90 on the hot side and humidity is around 60. I dont know if something is wrong with him or if he's sick... Any help will be welcomed!
