RI? Hissing? Please help

All right, my male pastel recently when being first picked up out of his tub will make a hiss noise and acts rly nervous. I don’t know why I assume being switched from a tank to a tub might of stressed him. He only makes the noise when you first pick him up

Back to the hissing after reading about RI I don’t think it is that I took him out for over an hour put him on my table top and watched him he never made a wheezing noise or hissing.

Any ideas on why he may be doing this he just recently locked up several times with my female ball there tubs are right next to each other would that cause stress or anything? Just trying to figure out why he has become shy or agitated when first brought out of the tub.

When I put him away I looked down and it looked like he was repeatedly yawning? I'm going to take him out in amin put his face near my ear to see if I hear anything

I'm just freaking out because of what I have read about RI and others people.

Whenever you change their environment it usually takes about a week or so for them to adjust to the new changes. It sounds like he is letting you know that he is unhappy at being disturbed. The best thing you can do when they hiss is to continue handling them. If you back down when they hiss, they will start associating hissing with being left alone and will just do it more. If you are concerned about a possible RI, then listen for any wheezing, gurgling or popping sounds when they breathe. It sounds almost the same as when a person gets bronchitis...

After I posted here I caught him yawning repeatedly in his tub. I took him out for about 15min and pretty much forced his head near my ear. Every 30 seconds or so I would here a gasp of air. I'm very worried that this just came all of a sudden? I removed him from my rack and he is now in another room in the house.

I called a vet and will hopefully get him in for an appointment. My main question and concern is my other BP's. Would you do a complete clean down of tubs bleach out clean everything then re house them?
