Collection: Plecostomus

Originating from the fast-moving streams and rivers of the Amazon basin, Plecostomus are members of the Loricariidae family—armored catfish known for their sucker-like mouths and ability to cling to rocks and glass. Over time, these fish have adapted to a wide range of environments, making them both hardy and adaptable to aquarium life.

At AquariumFish.com, we proudly offer one of the largest selections of Plecostomus in the trade. From peaceful algae grazers to bold, carnivorous species, we have a Pleco for every tank and every aquarist. Whether you’re caring for a planted nano tank or a large show aquarium, there’s always a Pleco that fits perfectly.

The Many Faces of the Pleco

Plecos come in a broad range of colors, sizes, and behaviors. While most are omnivores, each species has unique feeding habits. Some, like the Vampire Pleco, prefer a meaty diet, while others—such as the Green Phantom Pleco—are dedicated algae eaters. These fish are hardy, adaptable, and bring both function and fascination to your aquarium.

• Vampire Pleco (L-240) – striking black coloration with white spines; carnivorous
• Green Phantom Pleco (L-200) – vivid green body; excellent algae grazer
• Blue Phantom Pleco (L-128) – deep blue hue with spotted pattern; gentle and hardy
• L-10A Red Lizard Pleco – small, slender species ideal for nano tanks
• Alligator Pleco – large, armored species suited for aggressive community setups

As our founder often says, “There is a Pleco for every tank.” From the peaceful L-10A Pleco for small aquariums to the rugged Alligator Pleco for predator systems, these fish bring beauty, balance, and personality to any aquarium. We believe every aquarium should have at least one Pleco.
