Hey, thanks for the pic - and nice vivarium setup!
I am looking forward to keeping some species within the Coelognathus genus myself - maybe some C. subradiatus soon...
I have to agree with Doug on the respiratory issue re: the clicking sounds. The only normal vocalization from any ratsnake, that I am aware of, is hissing - which is used as an aggressive warning. With most snakes, respiratory issues are usually due to too wet, too dusty, or too dirty conditions. - But with some of the tropical Asians from moist habitats, too dry conditions can cause respiratory as well as shedding issues.
