Myriophyllum guyana

Alternate Names:

Myriophyllum guyana is a great foreground option that can form tidy low growth and add texture, especially when given stable conditions and patience. It adapts well with or without CO₂.

Care At-A-Glance

Difficulty: Easy to moderate

Type: Stem

Size: Generally less than 20cm. Pruning will keep the plants much shorter and bushier

Position and Usage: Foreground to midground placement. Can be used as a background plant in nano-aquariums

CO2 Requirements: Not required but will result in faster, denser growth

Growth Rate: Moderate to Fast

Lighting: 2/5 – 5/5

Water Conditions: 18 - 28°C (65 - 83°F)

Propagation/Reproduction: Cuttings Special Requirements: Very few specific requirements. Normal aquarium substrate with root tabs is suffficient and a regular fertilization regime should be enough. This plant does not need CO2 but like all aquarium plants, will benefit from CO2 fertilization all the same. INVASIVE SPECIES POTENTIAL: Though not current listed as an invasive exotic in either Canada or the United States, other species of Myriophyllum (that we do not sell) such as M. spicatum (Eurasian Milfoil) have become major invasive pests in waterways throughout the continent. Because of it's fast growth rate and wide tolerance to a variety of water conditions, this species could potentially become a threat to native habitats in North America. It is tolerant of lower temperatures than Myriophyllum mattogrossense or Myriophyllym propinquum and can therefore pose a threat across the entire continent - including but not limited to the Great Lakes. Please be mindful that we need to protect the biodiversity of our precious native waterways and NEVER intentionally release this plant into the wild! Extra cuttings can often be traded for store credit at your local fish store. They can be properly disposed of by placing the cuttings in a plastic bag and sealing it before tossing them in the trash. If you want to go one step further to protect our waterways, freeze, boil or soak the cuttings in bleach before disposing

Detailed Information

Overview

Myriophyllum guyana (Guyana Milfoil) An particularly unique species of Myriophyllum, M. Guyana is perhaps the smallest plant in the genus and branches readily for a naturally attractive bushy growth habit making it absolutely perfect for nano-aquariums or even foreground placement  in larger tanks.

The leaves are a refreshing shade of light green and are generally smaller than similar plants such as Myriophyllum propinquum or Myriophyllum mattogrossense . It thrives in low-tech plant aquariums without CO2 injection or even a lot of light but does better with a good amount of lighting. This beautiful and somewhat unusual species is perfect for aquarists of all skill levels and looks great as a part of any aquascape.
