I know, you're probably thinking about the title of this post and wondering If I've gone over the edge and I understand that. After all, I am not a hamster, I realize that there's probably like three people on the planet that are concerned about whether or not fish worry and it's pretty likely that two of them are seriously bent. Personally, since there's not much of a wrinkle cream market for fish, they probably don't worry much at all. This is especially true if it's anywhere close to true about fish only having about three seconds worth of short term memory.
On the other hand, if you look at this picture from the fish's point of view, then it's pretty easy to understand the potential concern. And before anyone asks, I received the picture in an email and have no idea where it originally came from.
