 Cat-eLog Data Sheet | |
|---|---|
| Scientific Name | Leiarius marmoratus (Gill, 1870) |
| Common Name(s) | Achara Catfish, Marbled Pim |
| Type Locality | Rio Maranon and Rio Napo, Amazon Basin |
| Synonym(s) | Sciades marmoratus |
| Pronunciation | mar mo rat uss |
| Etymology | The genus name is derived from Leios, meaning smooth and Arius which is a Greek for "dealing with Mars, warlike, belliose". It's the name of another catfish genus, so the combination is "smooth Arius". This specific epithet refers to its long (longus=long) barbels (barba=barbel). |
| Species Information | |
| Size | 800mm (31.5") SL. Find near, nearer or same sized spp. |
| Identification | Often confused with the rarely, if ever, encountered Perrunichthys perruno. The fishes are identical in terms of colouration although P. perruno has 8 (1 hard and 7 soft) dorsal fin rays, Leiarius has 10 or 11. Also similar to L. pictus, these two can be distinguished by L. pictus having a larger dorsal fin albeit this feature reduces with age. |
| Sexing | Unknown. |
| General Remarks | There is some history of confusion in the Leiarius genus. L. marmoratus was for some time a synonym of L. longibarbis, but it was taken out of synonymy by Ferraris in his Catalog of Catfishes (2007). Fish are still sometimes seen as L. longibarbis, but most likely they are L. marmoratus. |
| Habitat Information | |
| Distribution | South America: Amazon and Orinoco Basins Amazon (hover or click on these areas to show maps or find other species found there) Orinoco  (hover or click on these areas to show maps or find other species found there) |
| pH | 5.8 - 7.4 |
| Temperature | 21.0-25.0°C or 69.8-77°F (Show others within this range) |
| Other Parameters | Requires clean, regularly changed water can become listless and loses appetite if a regular water change regime is not adhered to. |
| Husbandry Information | |
| Feeding | Young fish will eat virtually anything, especially small tankmates. As the fish matures it should be fed less often and periods of fasting will maintain the fishes health as well as provide the aquarist with a more active pet. Aside from large catfish pellets, feeder fish, crab, prawn and crayfish are also taken. The more adventurous aquarist may also try large earthworms, maggots and small cubes of raw beef heart (taking care to remove all traces of fat). |
| Furniture | Large, thick branches or bogwood roots to provide cover over a rounded large pebble base is ideal. Sand is often ''re-arranged'' by larger fish and coarse gravel can irritate or even damage the fish. An open area for night time exercise should also be provided. |
| Compatibility | Peaceful, although care should be taken to house with appropriately sized tankmates. |
| Breeding | Unreported. |
