Over the last 24 hours, my two Yellow Ogon have turned a darkish grey,
except their tails. We had storms and torrential rain yesterday, and water temp had dropped 4
degrees in that time. Could that be the problem? Will it reverse?? Other ideas??

Usually sudden color changes are related to water quality. So it will be
interesting to see what your's tests out to be. Besides pH you'll need to
test KH, buffering. Not enough buffering causes pH to crash. ~ jan
