The walking catfish (Clarias batrachus) is a species of freshwater airbreathing catfish native to Southeast Asia. It is named for its ability to "walk" and wiggle across dry land, to find food or suitable environments. While it does not truly walk as most bipeds or quadrupeds do, it has the ability to use its pectoral fins to keep it upright as it makes a wiggling motion with snakelike movements. This fish normally lives in slow-moving and often stagnant waters in ponds, swamps, streams and rivers, flooded rice paddies or temporary pools which may dry up. When this happens, its "walking" skill allows the fish to move to other sources of water. Considerable taxonomic confusion surrounds this species and it has frequently been confused with other close relatives.
Characteristics and anatomy: The walking catfish has an elongated body shape, and reaches almost 0.5 m (1.6 ft) in length and 1.2 kg (2.6 lb) in weight. Often covered laterally in small white spots, the body is mainly coloured a gray or grayish brown. This catfish has long-based dorsal and anal fins, as well as several pairs of sensory barbels. The skin is scaleless, but covered with mucus, which protects the fish when it is out of water.
One main distinction between the walking catfish and native North American ictalurid catfish is the walking catfish's lack of an adipose fin.
This fish needs to be handled carefully when fishing it due to its hidden embedded sting or thorn-like defensive mechanism hidden behind its fins (including the middle ones before the tail fin, like the majority of all catfishes).
Taxonomy, distribution, and habitat: The walking catfish is a tropical species native to Southeast Asia. The native range of true Clarias batrachus is only confirmed from the Indonesian island of Java, but three closely related and more widespread species have frequently been confused with this species. These are C. magur of northeast India and Bangladesh, a likely undescribed species from Indochina, and another likely undescribed species from the Thai-Malay Peninsula, Sumatra, and Borneo. The undescribed species have both been referred to as Clarias aff. batrachus. At present, the taxonomic position of the Philippines population (called hito or simply "catfish" by the locals) is unclear, and it is also unclear whether South Indian populations are C. magur or another species. As a consequence, much information (behavioral, ecological, related to introduced populations, etc.) listed for C. batrachus may actually be for the closely related species that have been confused with true C. batrachus. True C. batrachus, C. magur and the two likely undescribed species are all kept in aquaculture.
Walking catfish thrive in stagnant, frequently hypoxic waters, and are often found in muddy ponds, canals, ditches and similar habitats. The species spends most of its time on, or right above, the bottom, with occasional trips to the surface to gulp air.
Diet: In the wild, this creature is omnivorous; it feeds on smaller fish, molluscs, and other invertebrates, as well as detritus and aquatic weeds. It is a voracious eater which consumes food rapidly, so it is considered harmful when invasive.
Aquarium: A white variation with black patterns is commonly seen in the aquarium fish trade. However, this color variation is also prohibited where walking catfish are banned. Very well-rooted plants and large structures that provide some shade should be included. Any tankmates small enough will be eaten.
