my res has been doing something strange lately... he kind of streches his neck and opens his mouth and makes a clicking sound... hes been doing it a lot ... is that normal????

My turtles never done it....

There's some older posts about this if you try using the search function... I'm sorry but I don't remember the exact details in them or the conclusions.

Does it happen when they are basking/out of water for extened periods of time or in water? Is a frequent or is loud?

he dis it as was waking up ... kind of streched his neck and made the sound... he didnt open his mouth wide while doing it, he was on his basking area when he did ... any way i took him out of his tank and let him roam around the room and he was fine ... and hes eating normally

I once had a RES that would make clicking noises when he was becoming dehydrated, and if yours was on the basking area when he did it, perhaps this could have been why as well. It would be good to keep an eye out for other unusual behavior/symptoms, though, just in case.

mine used to do this when and i figured it was the water popping when he opened his mouth...doesn't do it anymore though so i really dont know what it was

My turtle hisses at me alot, or at least thats what I think he's doing, it sounds like he's wheezing but I doubt it's RI. I heard they make noises if you bother them as he does not like being out of the water involuntarily. (He'll do it when I place him in the empty sink for a few minutes, and now he'll go for my fingers and withdrawal after a hiss)

They'll make a hissing sound when they've been startled and quickly tuck their heads in their shells. The sound is caused by air escaping from the lungs to make room for the head. They'll also hiss if they feel threatened, with their heads out of their shells, though.
