|Size||350mm or 13.8" SL. Find near, nearer or same sized spp.|
|Identification||Pterygoplichthys can be identified by the number of rays in the dorsal fin. Ten or more dorsal rays (usually more than 10) indicates that it's a Pterygoplichthys. Most other plecos have 8 or fewer rays (in particular the larger Hypostomus species that are most likely to be confused with Pterygoplichthys).
Is also L023. A relatively nondescript species that is unlikely to be imported as an L number. An amelanistic form has also been fixed by US and SE Asian commercial fish farms and is commonly sold as the "chocolate pleco". As they are bred in huge numbers by commercial fish farms, this is currently the most commonly available loricariid and can be found for sale in nearly all the larger chain-type pet stores.
This species is most likely to be confused with P. disjunctivus. The pattern on the abdomen is the most useful external key: P. pardalis has a spotted pattern, where P. disjunctivus has a vermiculated pattern. For more info see: Zootaxa 1109: 57-68 (2006)
|Sexing||Comparison of the genital papilla in mature fish shows the differences in the sexes to the trained eye. In males this is a small yet thick stump which noticeably protrudes from the fish's undercarriage. In females it is less obvious and is recessed or lies flat with the body.|
|General Remarks||It is important to note that the term "common pleco" is applied to several nondescript loricariid species, especially of the genera Pterygoplichthys and Hypostomus.|
|Distribution||Widespread in the amazon river system.
