L528 Pleco - Rio Paraguay Bristlenose Pleco (Ancistrus sp. "Rio Paraguay") – Tank-Bred

Species Overview

The Rio Paraguay Bristlenose Pleco (L528 Pleco) (Ancistrus sp. "Rio Paraguay"), also known as the Redspot Pleco or Redspot Bristlenose Pleco, is one of the most exciting Bristlenose Plecos available in the aquarium hobby today. This stunning species combines the manageable size and algae-grazing abilities of a traditional Bristlenose Pleco with a truly unique pattern featuring cream, black, and reddish-orange spotting.

Unlike many plecos that eventually outgrow community aquariums, the Rio Paraguay Bristlenose remains compact while still developing impressive coloration and patterning. Every fish displays its own unique markings, making each specimen a living work of art. As they mature, many individuals develop increasingly dramatic contrast and spotting, making them highly desirable among pleco collectors.

Our Tank-Bred and Locally Bred Rio Paraguay Bristlenose Plecos are aquarium-raised and exceptionally well adapted to life in captivity. Locally Bred specimens are offered at a larger purchase size, making them an excellent choice for hobbyists seeking more developed fish with emerging adult coloration and body structure. Whether you're looking for a hardworking algae grazer, a standout community fish, or a collector-worthy pleco, the Redspot Pleco checks every box.
