There was a question about the bass, and may be other fish, in Bass Pro's aquariums. I believe also the tanks in question are located in Springfield, although other shops may have the same issues.
The question was what causes fish's eyes to bug out. I enquired and got the following answer from MDC fisheries pathologiest Devona Weirich, DVM
The answer to your question is: yes, one of the most common causes of pop-eye is nitrogen supersaturation of water. This is common in water sources that are spring or well fed as well as below dams where gases are compressed due to falling water. In these instances, along with bulging eyes you may see pockets of gas under the skin or in gill tissue. Now the other very common cause of pop-eye is a bacterial infection. With these you may also see a reddened fin base, a distended abdomen, or frayed fins. If you cut the fish open you may also see fluid in the abdomen or other hemorrages on internal organs. It is best diagnosed by a bacterial culture. Determining the cause of pop-eye is sometimes not easy. I have taken bacterial and tissue samples from aquarium fish with pop-eye and found neither a parasite, bacterial infection nor gas supersaturation. My conclusion at that point was that the tissues around the eye were permanently damaged by some prior event that is now undetectable. If the fish are eating well and do not show external signs of disease, this may be the most likely situation.
