Abstract
A taxonomic and biogeographic study of the introduced suckermouth armored catfishes locally
known as “janitor fish” is briefly described. Specimens were collected from five sites in the Laguna
de Bay basin and were examined for 19 meristic and 37 morphometric characters and other external
features including coloration. Results were compared with existing literature on fishes in the family
Loricariidae. Examination revealed that specimens of janitor fish, previously reported as
Hypostomus plecostomus, actually belong to the genus Pterygoplichthys, family Loricariidae.
Collected specimens consisted of two species—Pterygoplichthys disjunctivus and Pterygoplichthys
pardalis. Both species were collected from the five sites except in Pasig River where only P.
disjunctivus was collected.
Key words: Janitor fish, Pterygoplichthys, sailfin catfishes, Laguna de Bay, Philippines, introduced
species

Was ich persönlich interessant finde, ist, dass neben P. pardalis auch P. disjunctivus häufig gefangen wurde.
Nomalerweise werden ja nur Tiere ausgewildert (und fassen dann auch noch Fuß), wenn sie im Hobby häufig vertreten sind/häufig gehalten werden.
Von P. disjunctivus im Aquarium habe ich aber noch nichts, oder nur sehr selten gehört. Oder handelt es sich um eine Fehlidentifikation? (Bei wem? Bei den Aquarianern oder im Artikel)?
