Nope. nothing like that whatsoever. But sadly he expired during the night, around 4 AM. I am still amazed, this came on so fast, yesterday morning he was active, eating, drinking ... the only difference was coloration as I described.
Despite being away for about 20 years, I am not a total novice to sticky tongues. I've had in the past a beautiful male Parsons for over 7 years, several Jacksons, Jeweled, Veiled, a breeding pair of Mellers, and many others. But, I've never encountered anything like this.
