The world chameleon comes for two words in latin. Chami, meaning geo (Earth) and leo meaning lion. The name is given for good reason. They have the colors of the earth and the disposition of a lion. I personally take aggression as a good sign of health. After you have a sick one you will...
He could have hyperextended the tongue. This occurs when they misjudge distance. They aim further then the insect is. When this occurs it cause the tongue to force it self outward instead of straight. When this occurs most people just report their chameleon's shoots looking a little weird...
I majored in fast women, drugs and late nights. Of course this might have something to do with why I never graduated high school. Guess that doesn't count for anything. Oh well things still worked out in the end.
Stay in school kids.
What do you mean by eye popping out?
Have you seen his tongue come out at all?
Could you elaborate on what type of dusting you are doing and the frequency in which you are doing it?
What type of UVb source are using and how old is it?
I wouldn't try it. Do not have a local pet store near you? You could at least pick up enough crickets to last tell you get your order. Fish/Bait stores have crickets a lot of times too.
I don't think you will be saying that when he gets full size.
You can try to hand feed him. Take a cricket or other feeder in one hand and make it to where he has to advance onto your other hand in order to get closer. It does take them awhile to get the hang of it but it can be effective...
I would advise against feeding him superworms at that size. Veileds are pretty excitable eaters at times so he will probably get them down but you have to worry about them coming out. They are high in chitin. A little chitin in a chameleons' diet is great it acts in a similar fashion as fiber...
The chameleon tongue can and will stick to anything. It really just depends on how they hit it as to whether or not it is going to stick. In extreme situations tongue injury, even amputations from tongue mishits. These are fairly uncommon though.
On the other hand the chameleon tongue can...
I would go by size rather then age. They all grow at different rates. I have seen almost full grown veileds at the 6-8 month range. I would say 6-7" overall length is as small as you should sell them, at least out right to unknown buyers. I would think 8" would be more preferable.
I would just add that it is a little more natural for the temperature to drop at night for chameleons. Most houses will not drop into dangerous temperatures unless you live in an extreme climate or the power goes off in winter. So normally night time heating is nothing to worry about.
I would suggest more branches in the upper region of the cage. This will give your chameleon multiple temperatures at which to get comfortable at, keeps your chameleon off of the screen and should make hunting easier. Crickets are like chameleons in that they need outside heat to regulate...
A vet is not really going to be able to do much for a chameleon that size. They are far to small to take a blood sample and medicating something that size is not really feesible.
In your picture the one to the right looks as though part of his tail may have gotten chopped off or something...
Sorry to hear that. Believe me I understand. One of my jacksons has been battling off an eye infection for awhile now. I fear if things don't improve soon for him, he may not make it.
