Visit an aquarium, and you'll find plecos in no short supply. These insightful scavengers are unique and fascinating to watch, and they serve a real purpose hovering on the tank's bottom. They help keep your tank clean and prevent harmful nitrates from taking over the water by gobbling up unwanted algae, leftover matter, and uneaten food. Not all plecos are created equal, however. With over 150 varieties discovered, some key facts will help you narrow down the best pleco types for your home tank.

Zebra

Zebra plecos live up to their name as an eye-catching anomaly in the fish world. Covered in zebra-inspired stripes, these scavengers grow 3.5 inches long with prominent fins, a colorful tail, and a large sucker mouth surrounded by whiskers. Shy and nocturnal, they hide out during the day and thrive on a diet of blanched vegetables, algae wafers, and bloodworms. Since they tend to feel threatened and hide out frequently, drop food near their hiding spots, and you'll quickly get on their good side.

Snowball

The snowball pleco has a unique appearance with sporadically placed spots and an uneven shape. While they generally have a black, brown, or gray base shade, it's their bold white or yellow spots that attract attention. Hailing from Venezuela's Rio Negro, these fish thrive in the world's largest blackwater river, so they'll need similar accommodations at home, including water temperatures reaching up to 86 degrees, a strong current, and a variable pH balance between 5.8 and 7.6. They love spending their days hiding in dark caves and driftwood, so load up on the hiding spots.

Peppermint

Peppermint plecos are black or dark grey with tiny white dots, which helps them blend in with rocks in their natural environment. Native to rapidly-moving Brazilian rivers, they latch on to those rocks at the bottom to hide from predators, and they grow up to seven inches in length. With visible teeth and bony plates for protection, peppermint plecos might appear frightening, but as long as their daily needs are met, they stick to themselves. You'll need your own strong, fast-moving stream with ample rocks to accommodate them.

Bristlenose

Originating in the fast-flowing Amazon waters of South America, bristlenose plecos are impossible to miss with their wide, bristle-covered heads and wide bodies covered in light dots. They range in shade from brown to black, with some individuals taking on a green or grayish appearance. Since they grow between 3 to 5 inches long and are relatively easy to care for, these bottom dwellers are a welcome addition to any tank. Their water and pH requirements are average, and they love consuming as much algae and protein-rich snacks as possible.

Sunshine

Regarded for their vibrant yellow or bright orange edging, sunshine plecos are a standout species. Rich colors differentiate them from the standard brown, gray, or black varieties, but their care needs are similar. Like other pleco varieties, the sunshine pleco requires plenty of algae and driftwood. Hiding places are essential; they love marking their territory and staying relatively reclusive and shy. Be on the lookout, however: these foot-long scavengers often chow down on invertebrates, so any snails, shrimp, or crabs in your tank are at risk.

Clown

Clown plecos are beautiful to watch, as their black base is covered with thin yellow or orange stripes, enlarged fins, and a 3.5-inch length. About the most low-maintenance species you could own, they're great for beginners and can survive and thrive for over a decade with a neutral pH and temperate waters. Algae is the clown pleco's go-to meal, and they love using driftwood as their hiding space, foraging area, and play place.

Vampire

If you're craving an interesting watch, then the vampire pleco might be your perfect fit. Their eyes dilate to align with the light level, so they change frequently throughout the day. These long, slender creatures have expansive fins with brown, gray, or black coloring and light spots. Within your tank, however, you might want to watch out. Vampire plecos remain calm for the most part, but they also become territorial and inflict damage on any fish that threatens their go-to spot.

Originating from smooth-flowing Brazilian rivers, golden nuggets lives up to their name. They're covered in yellow spots against a black base, providing a striking appearance that stands out in your home aquarium. A tropical freshwater habitat is all you need to get these easygoing plecos thriving; they're low-key about water and food and reach just 7 to 10 inches in length, so care isn't difficult. While they're active at night, during the day, they're calm and keep to themselves, forging on a healthy diet of algae and protein.

Royal

Royal pleco

Native to the Amazon Basin, royal plecos are mutually colorful and intimidating. They grow up to 17 inches long and can become aggressive and territorial. In your home aquarium, they'll find a spot they love and stay there while keeping competitors at bay. Royal plecos vary widely in appearance, but you'll find the most common color combination is gray and black with a light gray base. Their huge bulbous eyes make them unmistakable in any setting.

Blue-eyed

At two feet long, the blue-eyed pleco is an intimidating creature. These blue-eyed omnivores are the largest and rarest plecos on the planet, thriving in rapidly-moving Columbian waters. They require a strong water flow at home to get comfortable, plus plenty of driftwood to hide or go grazing for algae. Dark gray coloring and thick armored plates add to the fear factor, but these creatures only chomp on shrimp, bloodworms, chopped mussels, and plants.
