Ok, I know that RES can carry a virus that can be deadly to Painteds. What is the virus and how would you know if they are carriers? I've had two of the RES for 20 years and one that I just rescued (which is the one I would trust the least). Is there a test for this virus?
The Painted I found on a golf course as a hatchling a year ago. He was lucky, they were mowing that fairway and he wouldn't have lasted long under the gang mower. He's now nearly 4 inches and I'd like to eventually move him into the pond outside with others if it's safe.
