Chiselmouth Catfish

Adults of this species reach a length of about 4 cm. Their body is covered with hard integuments with numerous sharp spines. The head is reliably protected by bony plates. The eyes are located on the top of the head and oriented upwards. The first rays of the fins in these fish are modified into spines. One of the most remarkable features is the structure of the mouth: it is elongated and flattened, resembling a chisel in its shape, which is reflected in the species' name. The coloration is usually yellow-orange, with three dark bands encircling the body.

The natural habitat of this catfish extends throughout Southeast Asia, including the Ataran River basin, which mostly flows through Karen State in Myanmar, bordering Thailand to the east. The headwaters of the river are located in hilly and mountainous areas. The typical biotope is characterized by a shallow riverbed with a rocky or sandy bottom, where clean, clear water saturated with dissolved oxygen circulates.

These fish are peaceful and calm, showing activity primarily during feeding in the dark. They are more comfortable in a group, so it is recommended to keep at least 10 individuals. They get along well with many other non-aggressive species of comparable size.

For comfortable keeping of a group of 10 Banded Catfish, an aquarium of 80–100 liters will be required. In the aquarium setup, preference is given to sandy or rocky substrate, as well as creating piles of stones, rocks, and several large snags. From these decorative elements, shelters should be formed, the number of which should correspond to the number of catfish, where they can hide during the day. Introducing live aquatic plants is not necessary, as they are not characteristic of the natural habitat of this species. A key condition for successful keeping of the Banded Catfish is maintaining high water quality within acceptable temperature and hydrochemical parameters. The accumulation of organic waste, which can disrupt the nitrogen cycle, should be avoided. Regular maintenance procedures and equipping the aquarium with the necessary equipment, in particular, an effective filtration and aeration system, are the key to creating a healthy aquarium environment.

In natural conditions, these catfish forage among stones for small invertebrates. In an aquarium environment, they learn to accept live or frozen foods, such as Artemia, Daphnia, bloodworms, as well as specialized foods for carnivorous species. Since they are nocturnal, feeding is recommended after the main aquarium lighting is turned off.

Breeding has not been described. This is a small bottom-dwelling catfish from the fast streams of Southeast Asia, described by science only recently and rarely seen in aquaria. No data on its reproduction, in the wild or in captivity, have been published.

Most health problems in fish often arise from unsuitable keeping conditions. Maintaining a stable and comfortable habitat is a key factor for successful keeping. If symptoms of illness appear, the first step is to check the water quality. If deviations are found, it is important to take immediate measures to eliminate them. If the symptoms do not disappear or worsen, medicinal treatment may be required.

When choosing individuals, attention should be paid to the integrity of the fins and the absence of damage to the skin. Healthy fish should be active at dusk, and during the day, exhibit natural behavior, hiding in shelters or resting on the substrate. Avoid buying fish with signs of emaciation, sunken bellies, or an apathetic state under bright lighting, as this may indicate stress or hidden diseases. It is recommended to purchase a group of 10 or more individuals, as this species becomes extremely timid and prone to stress when kept alone.
