How to Care for a Pleco Fish

Keeping an aquarium is not only a great hobby, it is also an excellent way to learn about different types of fish. The Plecostomus, commonly known as the "pleco" or "sucker fish" is a freshwater, algae eater that can live in harmony with many different types of fish. There are many different species of pleco. You can find specimens ranging in size from two to four inches in length, but don't be fooled, some species of this fish can reach lengths of one to two feet. They are not difficult fish to keep as long as you take some time to learn about their needs and habits.

Instructions

      Check the water in your tank. In general, plecos do best in temperatures ranging from 68 to 72 degrees Fahrenheit, with pH levels between 6.0 to 7.5.

      Prepare the tank for your pleco. An established tank should already have plenty of areas for fish to hide including caves, rock formations and other decorations. Add these items if you do not already have them. Plecos are nocturnal and use these places to hide during the day. Add pieces of driftwood to the tank. Plecos like to gnaw on wood as a dietary supplement.

      Introduce your pleco into the tank. Do this by first floating the bag containing your pleco and water from your fish supplier in your home aquarium for about 15 minutes to allow the temperature in the bag equalize with the temperature of the aquarium. Once the temperatures have equalized, open the bag and gently release the pleco into the tank. Give your pleco time to settle in.

      Feed your pleco a diet of spirulina or algae wafers and fresh vegetables like cucumbers, lettuce and zucchini. Plecos will help keep your tank clean by eating any algae that grows in your tank.
