Plecos, short for Plecostomus, are popular freshwater aquarium fish known for their algae-eating abilities and unique appearance. Originating from rivers and streams in South America, these fish come in various species, with the Common Pleco and Bristlenose Pleco being among the most popular in home aquariums.

Care Requirements

• Lifespan: Plecos can live anywhere from 10 to 15 years, with some species even reaching up to 20 years with proper care.
• Tank Size: A minimum of 30 gallons is recommended for smaller species like the Bristlenose Pleco. Larger species, such as the Common Pleco, require at least 75 gallons due to their potential size of over a foot in length.
• Temperature: Plecos thrive in water temperatures between 74-80°F (23-27°C). Consistent water temperature is key to their health.
• Water Quality: Maintain clean water with good filtration. Plecos are sensitive to poor water quality, so regular water changes are essential to keep ammonia, nitrite, and nitrate levels low.
