Type: Stem

Size: Can grow to reach tank’s surface (maximum height 60cm) though pruning will keep the plants short and bushy enough to use in the midground

Position and Usage: Midground to background placement

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

Growth Rate: Fast/Very Fast

Lighting: 3 /5 – 5/5

Water Conditions: 24 - 30°C

Propagation/Reproduction: Cuttings Special Requirements: Nutrients are essential for keeping this fast growing but otherwise undemanding plant healthy. A standard iron-rich substrate or root tabs is recommended as well as regular water column fertilization. M. Mattogrossense likes warm water. 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 our native waterways - especially in warmer climates such as California, Texas and the Southeast US (Including Florida). 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
