It is indigenous to North America and can also be found in Central America, South America, Canada, the Caribbean, Mexico, and lastly, Asia. In the wild, it is mostly found near water bodies like ponds, flowing streams, brackish lakes, and freshwater sites. In few countries, guppy grass is considered an invasive species because of its growth in local canals and waterways.

Appearance

It grows underwater, has long slender stems with many branches. It can grow to 90 cm in height which is 35 inches. Its leaves are delicate, green, flexible oppositely arranged in whorls, and contain teeth on the edges. The leaves are up to 2 cm wide and 3cm long.

Biofilm is produced on guppy grass which is also a food source of shrimplets and baby fry.

It grows with great speed and can overrun the tank in no time if left unchecked. By overgrowing, it can block light. Its stem is pretty delicate and can break easily. The broken parts are also a problem because wherever they fall they grow into new plants. when planting ensures to give it proper time so it can acclimatize to the tank environment.
