Know nothing about fish - help me ID what I saw?

Whew, I'm real glad that I'm not the only person with a phobia of fishes... It stems from being grossed out by some pf the fish types and the horror stories of fishes constantly dying, killing and consuming each other. How do you guys deal with it? Having an fishbowl seems so stressful!

Is it normal for Plecostomus to have giant, bulging eyes that almost fall out out of their heads? I've seen one like this in a shop and felt horrified. Other than that, those are adorable. They can get huge, though.
