I have five spotted turtles in a Waterland tub. They have been thriving, but I noticed yesterday that one apparently has pneumonia, i.e. floating and tilting in the water. I am taking her to the vet today.
I have read that one of the causes is cold temperatures. I have been keeping water at 72 degrees because I have been told spotteds like it cool. I also have basking site with UVA/UVB/heat lamp. Is this too cool? Any other suggestions to prevent pneumonia? Is pneumonia contagious?
