Good deal and nice fish - I have a Mono that also has an damaged eye like your Kel.. My guess is that it was stung by a ray because the guy I got her from had it in a tank with a sand bottom and rays..Nothing else was in the tank to damage it's eye that I'm aware.. She's defiantly blind in that eye though and I have to make sure she knows when I'm feeding because she'll miss it and go hungry if I don't drop it in front of her good eye...hahahaha
Do you know how your Kel damaged its eye? Can he still see outta it?

Not sure what happened to his eye. From what I gathered from the LFS is that the kelberi was a trade in. He seems to be able to see out of it. Not sure if it's damaged or birth defect.
