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, they develop more defined spots and a richer coloration, especially in well-maintained tanks with stable water conditions.

Received my Rio Paraguay Bristlenose Pleco and it’s already showing beautiful cream and red spots. It’s very calm and spends most of its time grazing on algae. The tank looks much more vibrant now with this addition. A standout fish for any freshwater setup.
Jacob White –
The coloration is unique and each fish has a different spot pattern. It’s small enough to fit in a 20-gallon tank without overcrowding. Very active during the day and peaceful at night. Great for beginners who want a colorful, low-maintenance pleco.

It’s a beautiful fish with a distinct pattern. I’ve had it for three months and it’s still growing in color. A bit shy at first, but now it’s exploring the tank regularly. Would recommend to anyone looking for a visually striking pleco.
