Clarias batrachus • Clariidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Clarias batrachus** (Linnaeus, 1758)
Common Name(s)	Common Walking Catfish, Walking Catfish
Type Locality	Asia.
Synonym(s)	Clarias assamensis, Clarias assamensis, Clarias punctatus, Silurus batrachus, 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.
Species Information
Size	400mm (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.

pH	5.6 - 8.0
Temperature	20.0-26.0°C or 68-78.8°F (Show others within this range)
Other Parameters	Unimportant, the fish will prosper in a wide range of PH and water hardness.
Husbandry Information
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.
