Irwini Catfish

Irwini catfish share the pictus catfish's habit of constantly sweeping long barbels through the water, tasting for food rather than relying on sight in low-visibility conditions — those barbels are covered in taste buds, essentially letting the fish "taste" the water before committing to a bite. Active and social, it does best kept in a small group, where that barbel-driven foraging turns into a constant group activity.
