I have little jacksonii he is6 months old, today I wanted to water plants in terarium, but he was hideb there, please and I split the water on him :-( he is not well now, please what can I do, he is opening his mouths.
If he is just vomiting then let him vomit. Dont disturb him.
If hes showing stress and cant perch then you can run him to the vet. But the moving and the trip( unless its just down the road) might cause him more harm than good in a vomiting situation. You do not want to disurb a vomiting animal. Its best to see if he can clear it out on his own. You can even take him to the vet after he gets himself stable if you feel hes not 100% after an hour or 2.
Well it looks like he is getting better. As other have stated you have a cold, wet, upset cham. Hes going to be cold colors. As long as he perches and isnt mouth gaping for air i think you are in good shape.
I would keep him warm and not disturb him. The more you play with him the less he is going to try to get rid of the dirt/water in his mouth.
