Coloration: The plant's overall coloration is green, with variations in shade depending on environmental factors like lighting and nutrient levels. Habitat: Gratiola viscidula is native to wetlands and marshy areas, often found in shallow waters or along the edges of ponds and streams. Care Tips: Lighting: Provide moderate lighting levels (around 2-3 watts per gallon) for Gratiola viscidula. While it can tolerate lower light conditions, moderate lighting promotes healthier growth and leaf coloration. CO2 and Fertilization: CO2 supplementation is not always necessary for this plant, but it can benefit from liquid fertilizers containing essential nutrients. Ensure a balanced nutrient regimen for optimal growth. Water Parameters: Maintain stable water parameters with a temperature range of 72-78°F (22-26°C), pH between 6.5-7.5, and moderate water flow. Good water circulation helps deliver nutrients to the plant. Substrate: Gratiola viscidula can thrive in a nutrient-rich substrate, but it can also grow when attached to driftwood or rock surfaces. Provide a substrate with good moisture retention. Pruning: Regular pruning helps control the plant's growth and prevents it from becoming too dense. Trim any overgrown stems and remove any decaying leaves. Propagation: Propagation of Gratiola viscidula can be done through stem cuttings. Simply cut a healthy stem and replant it in the substrate or attach it to a surface using fishing line until it roots. Uses: Foreground Plant: Gratiola viscidula can be used as a foreground plant in aquascaping layouts, adding a touch of greenery and texture to the front of the aquarium. Accent Plant: Its small size and unique leaf arrangement make it suitable as an accent plant, especially in nano or small aquariums. Habitat Enhancement: In addition to its aesthetic value, Gratiola viscidula provides shelter and grazing areas for small fish and invertebrates, contributing to a natural and dynamic aquatic environment. Overall, Gratiola viscidula is a charming and relatively easy-to-care-for aquatic plant that can add visual interest to freshwater aquariums.
