Perruno

About

Native to the Lake Maracaibo basin in northwestern Venezuela, this large South American catfish, Perrunichthys perruno, is a genuinely uncommon sight both in the wild and in the hobby. It belongs to the family Pimelodidae, the long-whiskered catfishes, and shares the characteristic long barbels and streamlined, scaleless body typical of that group. In the wild it is primarily a predator of other fish, so tankmates need to be chosen with care. Anything small enough to fit in its mouth is essentially a meal waiting to happen. Given that adults can reach close to two feet in length, that rules out a surprisingly wide range of companions. This is a fish that demands serious space and serious planning. A large, well-filtered aquarium with plenty of hiding spots and subdued lighting will suit it well, as pimelodid catfish tend to be most active after dark and appreciate shelter during daylight hours. Despite its predatory streak, it is not an aggressive fish in the conventional sense. It is simply an opportunistic hunter doing what large catfish do. Intermediate-level experience is a reasonable baseline here, mostly because the tank size commitment and dietary management are not trivial responsibilities.
