Pseudacanthicus sp. (L273)

Published / Updated


The unique L273 pleco is a South American Loricariidae that is found in the lower Amazon and Rio Tapajos. This Pseudacanthicus sp. is set apart by the unreal coloration (pinkish metallic coating) that some of this species, mostly males display.

Below you can find photo and video collection of the two Pseudacanthicus sp. L273 plecos that I have kept. They came with a semi bad condition (malnourished). Luckily both of them recovered fairly quickly. You might also be interested in these Pseudacanthicus species L114 pleco and L600 pleco which are some what similar to L273 pleco.
