How to Plant Aquatic Anacharis


The anacharis, also called the Brazilian waterweed, is a popular aquatic plant often used in aquariums, due to its quick, easy growth and ability to oxygenate the water. Anacharis creates a healthy aquatic environment for fish not only because it's a great oxygenator, but also because it starves out algae. Native to North and South America, the anacharis feeds on fish wastes and provides an optimal place for many fish species to lay their eggs.

Step 1

Cut away the rubber band that is holding the bundle of anacharis stems together. Cut the rubber band carefully with scissors. Retailers often also insert a strip of lead in the bundle, so remove that as well.

Step 2

Insert the shoot-like roots on the bottom of the stems shallowly (about 1 inch) into the gravel substrate layer in your tank. Space the individual anacharis stems about 1 to 2 inches apart.

Step 3

Arrange the anacharis stems so that the taller ones are toward the back of the tank and the shorter ones are in front. You can arrange the anacharis so that they're in front of your filter tube or heater to "hide" the tank equipment.

Step 4

Wait about two or three weeks before adding your fish to the aquarium, if you're setting up a new tank. This will give the anacharis time to grow, as well as to clean and aerate the tank water.

Tips and Warnings

  • Make sure you know which species of Anacharis you have, because certain species are suited for different environments. The species Egeria densa is best grown in a tropical aquarium, while the Elodea species are best for cool-water aquariums or ponds.
