Can giving my cham a small dose of iodine bought in the vitamin section of a drug store help this? Everything else as far as lighting, water, humidity, proper gut loading of crickets, and enclosure is fine. He exhibits no lethargy at all, still drinks fine, and now i have him eating from a cup. He does not like the cup idea at all and still puts forth effort at free range feeding but he only sticks his tongue out and tries to get as close to the cricket as possible with no avail. I assure you that his tongue has not been bitten off and if it was injured in any way, its been several months since the decline. Hes about four years old and i love him even if he cant use his tongue to smack those crickets for my own entertainment. I`m just at a loss as to what to do anymore. I`ve tried liquid appetite stimulants, special cleansing eye drops that not only cleanse but rid him of any microbes. He seems to be able to see very well. I just don`t know what to do anymore, so if iodine is a possible solution how many cc`s should I administer and how many times a day and for how long? I appreciate anyone reading and that has the proper knowledge on solving this dilemma! Thanks alot for your time and consideration. Peace cham lovers!!!!!!!!
