Eatophyllum demersum is known by many common names, such as rigid hornwort, hornwart (a frequent misspelling), and coontail. It grows very tall in the wild and will easily reach all the way to the top of your aquarium or pond. Normally hornwort is found floating at the water surface, but when planted in the substrate, it looks like a fluffy underwater bush with many long branches or side stems. The bright green leaves are thin and rigid, similar to pine needles. Much like water sprite and java moss, hornwort has dense foliage that provides excellent protection for baby fish and shrimp. Where is hornwort found? Hornwort can survive in a diverse variety of climates and is found on every continent except for Antarctica. It prefers to grow in still or slow-moving bodies of fresh water that contain lots of organic nutrients in the water column. Does hornwort clean water? Fast-growing plants like hornwort are good at “cleaning” aquarium water because they consume waste compounds from the water (e.g., ammonia, nitrates, and phosphates produced by fish waste and excess fish food) and use it to grow more leaves. With enough light and nutrients, hornwort can easily grow 1-4 inches (3-10 cm) per week. Do snails eat hornwort? Aquarium snails are detritivores and do not eat healthy plants but rather dying leaves and other organic debris. If you see a pest snail eating a plant, most likely the plant has some unhealthy leaves that the snail is cleaning up for you. Do goldfish eat hornwort? In general, plant-eating animals (such as goldfish, koi, African cichlids, and turtles) do not eat hornwort. Possible reasons could be the slightly serrated leaves, hard texture, or taste that makes it unpleasant as food.
