Blue Eyed Pleco Distribution, Population, and Habitat

Where to Find Blue Eyed Pleco and How to Catch Them

The natural habitat of the Blue Eyed Pleco is in freshwater areas of fast waters, though it prefers the Rio Magdalena, which is located in Columbia. Even if it is kept in a tank, you need to support the body with driftwood and a strong current, making the environment more like what it experiences at sea. They’ll use the driftwood as a hiding place, but they also will eat it as nourishment.

They are often bred as pets in captivity, so you should be able to find them in a local pet store. If kept in the home, the recommended tank size is 180 gallons. This tank size should be big enough to add some other fish instead.

Overall, the IUCN sees this fish as Least Concern. The population is steady as breeding is still somewhat lucrative.

Blue Eyed Pleco Predators and Prey

Though the blue-eyed pleco is omnivorous, it does not hunt any other animals. As an aquarium fish, you can feed it chopped shrimp, brine shrimp, chopped mussels, blood worms, and related foods. They can be frozen or live, and they can be fed vegetables as well, including cucumber, zucchini, and peas.

What eats Blue Eyed Pleco?

The Blue Eyed Pleco has to be paired with non-aggressive fish, so it is not eaten. In the wild, it is hunted by any animal that can get through its armored scales.

What does a Blue Eyed Pleco eat?

The omnivorous Blue Eyed Pleco will eat live or dead animals, though they typically don’t consume anything bigger than mussels or shrimp. Its diet also consists of driftwood and nearby vegetation, typically scooting along the bottom floor.

Blue Eyed Pleco Reproduction and Lifespan

Very little is known about the reproduction of the blue eyed pleco, though researchers believe they are cave spawners. As they lay their eyes, these fish prefer to find an area with fallen branches or other foliage, which will serve as food and a protective layer. Even breeding them can be difficult because their vents are hard to differentiate from.

Typically, this fish lays eggs on riverbanks and spawn, which is how so many have been located.

Blue Eyed Pleco in Fishing and Cooking

Originally, these fish were caught near Columbia. However, the recent legal restrictions make it a crime to do so. Now, the only way to get these fish at all is at a pet store, and they aren’t found in any recipes. Considering how hard they are to procure and find a good price for, the number of them and owners through the years has come down.
