Here is the bottom of one of my return pumps. The not so crowded one. I didn't take a photo of the other. They are good at what they do. They are also a good indication of your display husbandry as it relates to food and over feeding (which I do).
As I sort of joked about earlier gloving up is wise for many reasons for both parties (display and hobbyist).
