Respitory infection HELP!

I have a cb12 male bumblebee. I have been putting him in with my female pastel every 4-7 days. Recently he sits in the water bowl or will sit with his head upside down which im assuming is the spider gene head wobble. If i open the tank and touch him he will open his mouth and sit there making a weird sqeaking hissing noise but its quite quiet. Im not sure if this could be a respitory problem and i have a read a few horror sotries of other things it could be and im worry.

if anyone has any ideas please reply and thank you for your time :)

The pastel female is fine

It sound like he is warning you to go away.

Do you see any bubbles in his mouth or nose?
Do you see any phlegm on the sides of the tubs?

What are his temps/humidity?

No hes doesnt have any of those symptoms. He hasnt eaten for about four weeks he did strike for a rat but he didnt eat it. Hes just acting a bit funny. As for the noise i dont think hes hissing it just strange.

his tank temp in fine and so is the humidity.

I dont no if its because were moving him betweeen tanks or whether he just doesnt like our female pastel. He was fine last week when he was in there woth her though :/

Moving a snake won't cause a RI, it is most often caused by high humidity and low temps.
