|Size||470mm or 18.5" SL. Find near, nearer or same sized spp.|
|Identification||Clarias species are characterized by having an elongated body; a soft rayed dorsal fin extending to, or nearly to, the caudal fin base; a soft rayed anal fin extending from just behind the anus to the caudal fin base; pectoral fins each with a serrated anterior bony spine; head depressed, covered largely by firmly sutured, surface sculptured bony plates forming a protective helmet; four pairs of flagellate barbels (nasals, maxillaries, inner and outer mandibulars); air breathing organs derived from the 2nd and 4th epibranchials within a superbranchial chamber.
Shown above are the mottled or marbled colour variety and also the more commonly available pinky-white form. From time to time you also see the ''original'' brown with white belly wild form.
|Sexing||Mature males have small spots along the dorsal fin; it is not known if this also applies to the albino colour variant.|
|Distribution||Asia: Mekong and Chao Phraya basins, Malay Peninsula, Sumatra, Java, Borneo. Reported from Sri Lanka; popular for aquaculture in its native range but not regarded as such in other Southeast Asian countries. Trade restricted in Germany (Anl.3 BArtSchV). Several countries report adverse ecological impact after introduction.

|IUCN Red List Category||Least Concern, range map and more is available on the IUCN species page. Last assessed 2019.|
|pH||5.6 - 8.0|
|Temperature||20.0-26.0°C or 68-78.8°F (Show species within this range)|
|Other Parameters||Unimportant, the fish will prosper in a wide range of PH and water hardness.|
|Feeding||Anything; this fish is totally omnivorous and will gorge itself on most offerings.|
|Furniture||Very well rooted plants and large structures that provide some shade. Appropriately sized clay pipes seem to provide a readily accepted, if less cosmetically pleasing, hideaway for these fish.|
|Compatibility||Keep with large robust fish; anything small enough will be eaten. These should be fast growing or introduced as semi-adults. The walking catfish grows very fast indeed and although purchased at a ''safe'' size for it's co-inhabitants, this ratio will rapidly change to the danger of the smaller fishes.|
|Suggested Tankmates||Large Cyprinids (Silver Sharks, Tinfoil or Spanner Barbs for example) or Central American Cichlids.|
|Breeding||See Shane's World article.|
|Breeding Reports||There is but a single breeding report, read it here.|
