|Size||500mm or 19.7" 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).|
|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.|
