Blue-Eyed Panaque

Adults of this species can grow up to 28 cm in length. The catfish's body is robust, protected by a dense "armor" of bony plates. The coloration is predominantly dark gray. A striking and characteristic feature is its blue eyes. On its large head, there is a semblance of long whiskers, which on the sides appear as tufts of stiff bristles. Similar bristles are also located along the edge of the pectoral fins. The mouth, resembling a suction cup and studded with rows of short teeth, is located on the underside of the head and is adapted for consuming wood fibers and algae.

This catfish is an inhabitant of South American waters. Its natural range extends through the tributaries of Lake Maracaibo lagoon, located in northern Venezuela. It prefers to stay in the bottom layers, where it finds shelter among numerous snags and submerged fallen trees.

The Blue-Eyed Panaque is characterized by a nocturnal lifestyle, so its peak activity occurs during twilight hours. During the day, it usually hides. In spacious aquariums with a sufficient number of shelters (e.g., snags), this species behaves as relatively peaceful. However, if space is insufficient, competition for territory may arise, sometimes escalating into skirmishes. Good compatibility is observed with fish that inhabit the water column or near its surface.

For the comfortable keeping of one adult Blue-Eyed Panaque, an aquarium of at least 250 liters is required. Untreated natural snags are an important element of the decor, as this catfish feeds on wood fibers and algae growing on wood. Other decorative elements of the underwater landscape are not as significant. In natural habitats, the aquatic environment is stable, so for the well-being of the catfish, rather narrow ranges of temperature, pH, and dGH are necessary. It is sensitive to water pollution by organic waste. In addition to a continuously operating filtration system, regular aquarium cleaning is extremely important.

As mentioned earlier, the diet of Sutton's Panaque mainly consists of algae. In addition, the catfish readily consumes specialized sinking dry flakes, algae-based tablets, and pieces of fresh vegetables such as cucumber, peas, green beans, and potatoes.

Breeding is not documented. Panaque are cave spawners: the eggs are laid in a narrow shelter and the male guards and ventilates the clutch. This species is collected from the wild in limited numbers, large specimens need a great deal of space, and no reliable way to sex the fish or trigger spawning has been described.

This species is susceptible to diseases typical for armored catfish, which arise from improper keeping conditions. The most common are bacterial infections of the skin and fins, as well as parasitic infestations under stress or poor water quality. Fish are extremely sensitive to low oxygen levels and the accumulation of organic waste, which can lead to a general weakening of the immune system. Prevention involves maintaining high filtration intensity, regular water changes, and ensuring stable current.

When purchasing, attention should be paid to the fish's activity during twilight hours and the condition of its skin. Healthy individuals should have clean coloration without whitish film, ulcers, or fin damage. It is important to visually assess the fish's plumpness: a sunken abdomen is a sign of emaciation or internal parasites. At the store, it is recommended to clarify the keeping conditions and diet, as adaptation to new foods after capture from the natural environment can be difficult.
