Red Foot Tortoise is "Wheezing"

Hi. My red-foot tortoise, about 5 years old, seems to be "wheezing" and "sneezing". Sounds like a cold. He is still active, eating well, and otherwise seems fine. Nothing appears to be coming out of eyes or nose. Is there anything I should do to help what seems to be a cold? Thanks.
