I debated endlessly whether to give him Blacky's eyes or not. I ultimately decided that bettas are different than grubs and that he should have a normal "betta eye".
Blacky actually suffered a mishap a couple months ago - I SAT ON HIM, on my couch, for like three hours as I watched a movie! He was a total pancake by the time I realized I was sitting on him.
He's almost back to normal now, though. Lots and lots of fluffing!
