Panaqolus changae L-226

A Little More Information...

The Panaqolus changae L-226, also known as Iquitos Tiger - Momon, is a small Amazonian loricariid valued for its striped pattern and discreet behavior. Native to the Iquitos area of Peru, it inhabits quiet sections associated with submerged wood and natural substrates. This nocturnal fish becomes most active as the aquarium lights go out, exploring surfaces while searching for food. Its availability remains relatively limited in the aquarium trade, making it an interesting choice for Panaqolus keepers. A well-oxygenated, stable aquarium with plenty of shelter is essential for its long-term welfare.

General species description

Panaqolus changae L-226 is a small catfish belonging to the family Loricariidae and placed in the genus Panaqolus. Like other Panaqolus, it has a sucker mouth adapted to grazing on surfaces and a body protected by bony plates. Its activity is mainly crepuscular and nocturnal. It benefits from aquariums furnished with several shelters, especially tubes, cavities and pieces of driftwood. Despite its sturdy appearance, it is generally peaceful with similarly sized fish. Its availability is moderate to limited, and wild-collected specimens should be acclimated carefully.

Geographical origin and biotope

This species comes from northeastern Peru, in the Iquitos region of the Amazon basin. It is associated with the río Momón area, a lowland environment where streams pass through dense tropical vegetation. The biotope includes wooded banks, submerged branches and areas with sand, silt and plant debris on the bottom. Current strength can vary with season and location, but the fish seeks areas offering shelter and good water circulation. In the aquarium, warm, clean and well-oxygenated water provides a suitable basis for maintaining this species.

Precise location and local name

The trade name Iquitos Tiger - Momon refers to the Iquitos region and the río Momón in Peru. In the aquarium hobby, the designation L-226 identifies this form or population within the loricariid “L-number” system. The main local trade name is therefore Iquitos Tiger - Momon, while Panaqolus changae is the scientific name. This geographical information should be kept with the fish, especially in breeding projects, to avoid mixing populations or closely resembling forms.

Appearance and physical characteristics

Panaqolus changae L-226 has a stocky, ventrally flattened body covered with the bony plates typical of loricariids. The base coloration ranges from golden brown to greyish brown, marked by dark vertical bands that create a tiger-like pattern. The head is broad, the lower mouth forms a sucker, and the fins are relatively well developed. The bands can vary in contrast according to age, mood and lighting. The pectoral and dorsal fins have stiff rays and should be handled carefully during transfers. Adult size remains modest, making the species suitable for a reasonably sized aquarium when the layout provides enough shelter.

General diet

Panaqolus changae L-226 is an omnivorous loricariid with a strong plant and wood-based component in its diet. Natural wood should always be available in the aquarium, as it supports both feeding behavior and digestive comfort. Supplement it with spirulina-based wafers, foods formulated for catfish and blanched vegetables such as zucchini or cucumber. A small amount of protein-rich food can be offered occasionally, especially to juveniles or breeding adults, but it should not become the main part of the diet. Feedings are best provided after the lights go out, while ensuring that every fish can reach the food.

In your aquarium

Success with Panaqolus changae L-226 depends on stable, warm and well-oxygenated water, together with a layout containing real driftwood and several hiding places. A soft substrate, efficient filtration and regular water changes help reduce stress. Because it is mainly nocturnal, the lighting should leave shaded areas available. Offer varied food after the lights go out and avoid excessive competition on the bottom. With these precautions, this wild loricariid with a distinctive pattern can become a long-term resident of a peaceful Amazonian aquarium.
