Longnose Dace (Rhinichthys cataractae)
As a night owl of the freshwater world, this fish does its best work under the cloak of darkness. It feeds on algae, midges, black flies, mayflies, leaf hoppers, aphids, and more — all by starlight. Why the graveyard shift? Well, it's easier to avoid predation from other species, such as fish-eating birds and trout, in the wee hours. This late-night hunting is important because this homebody tends to stay in the same location throughout its entire life; and for some of these fish, home is where Superior is.
