Did you switch water source?
I see your feeding a smaller prey item and thats apparently working, I'm glad for you and your Corn
I anonymously bought a pair of Okeetees from Rich/Serpenco in late December, early January as part of 6 pack of Corn Snakes for Christmas presents for the family...just another random order...
I must say, all the Corns are absolutely gorgeous and are robustly healthy.
Superior, obvious quality specimens were shipped, my expectations were certainly exceeded and would not hesitate to order again. imho
