My chameleon this mourning when I offered him food got ready to shoot out his tongue like always but it did not come out all the way. It came from his mouth maybe 1 inch. This surprised me because usually he shoots out a good 9-10 inches of tongue, so I let him try again and he still could not get to my bug. I moved the bug closer and he got it, but he still refuses to shoot out his entire tongue. Any ideas to what his problem is? Please comment on ideas of what is happening and possibly how to fix it.
