I thought he had left the net and was in the bowl, but he wasn't. And he and I had been playing and a game, where he jumped up at my finger. So I was so focused on thinking he had jumped out of the bowl, I just didn't even think of looking in the net. Also, I had a new pair of bifocals, I wasn't used to, so I wasn't seeing too well either. It just seemed like a perfect storm of bad things. He was my first fish, and so I didn't know a lot of things. I guess you're right, I just have to let him go. I've lost cats before, but never when it was my fault like this. Thanks for listening.
