Dent eye?

[200xth]

This morning took out Achilles to get a weigh for feeding tomorrow and my Wife saw that he has a dent eye. We are able to see his pupil but it's dented in. There's no blood, no scratch, What could of cause this? Temps, humidity are fine. Bad photo achilles won't stop for a quick photo

It happens to everyone at some point. It's not usually anything to worry about.

Usually a minor hydration issue, most likely his humidity is too low.

Up his humidity. You can soak him once if you want, but upping his humidity alone will most likely correct it within a day or two.
