WOW...Something is weird.

I've given him Night Crawlers more than 2 weeks in a row as a baby. That is his main food source.

Lack of nutrition can also cause nurological disorders, but this is odd behavior and sounds like some kind of poisoning.

Edit; internal Bacterial Infections can also cause similar symptoms.

It's eyes being half shut as a baby would suggest nuro symptoms. In humans the occipital lobe of the brain controls eye functions. I do not know if this pertains to frogs.

Any chance he was actually sleeping? I know they usually dilate their pupils when asleep but I have heard that sometimes they can also shut their eyes.
