Two photos posted on Facebook show the teal or turquoise-like coloration on at least two different fish. According to the post, McDonald reports catching the fish in Navajo Lake in northern New Mexico one week ago, on August 19. (You can look at the photos on Facebook by clicking this link.)

“We caught nine large pike, six smallmouth bass and two largemouth bass,” McDonald wrote to NM Game and Fish. “Two of the fish I caught had a blue-green mouth and tongue. This is the first time that I have seen this.”
