What is the natural predator of the pleco in Brazil?

The natural predator of the pleco in Brazil is the fierce caiman. But in many regions, because it has no natural predators and has an extremely strong reproductive capacity, its numbers have surged dramatically, causing it to occupy the living space of native organisms and become an invasive species.

What does a pleco look like?

The pleco has a streamlined body, small eyes, a subterminal mouth, and a protruding upper jaw and thick fleshy snout. The upper and lower lips each have left and right 2 lobes, and the teeth are brush-shaped. The barbels are located at the corners of the mouth, 1 on each side. The gill rakers resemble a dense comb. The body is covered with black patterns, and the black stripes are clear. The base of the pectoral fin can produce sounds similar to those made by the yellow catfish. There are 2 dorsal fins, no lateral line scales, and only 4 rows of large scales on the sides of the body.

What food does the pleco eat?

The pleco often feeds on various kinds of debris at the bottom of the water, and when sick it will attach itself to other fish. It has an even more astonishing food intake: besides algae and moss, it can eat 3000~5000 fish eggs a day, and it will also swallow fry, though when there is delicious food available, it tends to appear rather picky.

In addition, when keeping plecos together with other fish, be careful not to let them breed, so as to avoid the death of ornamental fish caused by competition for food.
