|Cat-eLog Data Sheet|
|Scientific Name||Hypostomus plecostomus (Linnaeus, 1758)|
Almindelig Sugemalle (Denmark), Saugmaulwels (Germany)
|Type Locality||Suriname River.|
|Synonym(s)||Acipenser plecostomus, Hypostomus guacari, Loricaria flava, Plecostomus bicirrosus, Plecostomus brasiliensis, Plecostomus plecostomus, Pterygoplichthys plecostomus|
|Pronunciation||hi POSS tow muss - PLEK oss toe mus|
|Etymology||Greek, hypo = under + Greek, stoma = mouth. pleco = sucker, stomus = mouth.|
|Size||500mm or 19.7" SL. Find near, nearer or same sized spp.|
|Identification||Due to the number of species in the genus, identification is very difficult without exact provenance of the specimen. Most ''common plecos'' are now exported from Peru and Brazil. Photos of the real H. plecostomus are common in aquarium literature from the 1960s and 70s when ''common plecos'' were exported from Venezuela, Suriname, and the Guyanas.|
|Sexing||Large adult males possess thickened pectoral fins that turn reddish pink. Gravid adult females appear thicker when viewed from above.|
|General Remarks||Also found throughout the Orinoco basin, although some authors believe that Orinoco specimens may represent a different species. The photographs above are mostly of H. plecostomus from the Orinoco basin. Weber (2003) restricted distribution to coastal drainages of the Guianas.|
|Distribution||South America: Guianan coastal drainages. Have been introduced to several Asian countries for the aquarium trade.

|IUCN Red List Category||Not Evaluated|
|pH||6.5 - 8.0|
|Temperature||20.0-30.0°C or 68-86°F (Show species within this range)|
|Other Parameters||In nature, this fish is common in slower portions of larger rivers. It inhabits nearly every environment from riffles, the river banks, and driftwood snags.|
|Feeding||A true omnivore that will eat anything. The diet should be primarily vegetarian.|
|Furniture||Ideally a large tank with driftwood and a few caves. Substrate is unimportant.|
|Compatibility||Larger specimens can be territorial, but they rarely cause damage to tankmates. Smaller fishes are ignored.|
|Suggested Tankmates||Keep with medium to large sized community fishes or most American cichlids.|
|Breeding||Probably never accomplished. They normally spawn in holes in the river bank, but I have also captured this species in mountain rivers and ponds that did not have earthen banks. In these habitats it must spawn in caves formed by rocks and/or driftwood.|
