Guppy Grass Najas Guadalupens Portion LIVE AQUARIUM PLANT

Guppy grass, najas grass, or - scientifically - Najas guadalupensis, is a fast-growing plant that removes heavy metals, toxins, ammonia, nitrite, and nitrates from the water while producing oxygen. It consumes almost every free nutrient in the tank - giving little opportunity for algae growth.
Although the name implies that it's best for guppies, shrimp also love clinging to it as it has tons of nooks and crannies to pick food off of and hide within. Most small fish will also use it as a spawning mop, such as ember tetras, neon tetras, celestial pearl danios, and rainbowfish. It provides cover for the newly hatched fry and gives them a continuous source of microscopic food, such as infusoria.
Najas grass inhabits a variety of areas in the wild - from fast-moving rivers to stagnant ponds, freshwater to brackish, and temperatures ranging from 50 - 86F (10 - 30C.) Salinity levels under 8 ppt (or 8,000 ppm) seem to be an acceptable range, but it may be able to go higher. There's almost no tank or waterway that it can't inhabit.
