|All Fishes Data Sheet|
|Scientific Name||Clarias batrachus (Linnaeus, 1758)|
|Common Names||Common Walking Catfish
Clarias Catfish, Albino Walking Catfish, Piebald Walking Catfish, Vandremalle (Denmark)
|Type Locality||Java, vicinity of Bandung, Indonesia.|
|Synonym(s)||Clarias punctatus, Silurus batrachus|
|Pronunciation||klar ee ass - bat rah chus|
|Etymology||Clarias: From the Greek chlaros, meaning lively; in reference to the ability of the fish to live for long periods out of water.|
|Size||400mm or 15.7" 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.|

|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.|
