most people buy plecostomus because they clean up algae that builds up inside the tanks. what most people don't realize is is that plecostomus shouldn't be used unless they have a 40-gallon tank. believe me, i've seen them grow to the size of a fist! shrimps are the best way to go with tanks smaller than 5-gallons. freshwater snails should be used for the rest unless working with a 40-gallon or greater.
