Aren't Otos great? They might be my all-time favorite fish. Not only are they useful as algae eaters, but they are amusing to watch.... They're always busily munching their way along plant leaves, or else you find them in the most unusual positions (like hanging upside-down on the underside of a leaf). And with their big eyes, they are as cute as puppy dogs!
