Polygonum sp. “Pink” is not strictly upright like other knotweed species which are widely used as aquarium plants. However, it spreads and ramifies at short durations. It leads the plant to develop a dense bush. The best part is this bush is easy to maintain and doesn’t create any hindrance for the fish. If you want your aquarium to get Japanese-style nature aquarium outlook, this plant is perfect to choose. The plant has the tendency to lose the lowermost layers of the leaves.
Hard/soft plant: Hard plant
Ideal water temperature: It requires a temperature between 20 to 30 °C.
Lighting conditions: This plant requires strong light. Metal halides, T5s or power fluorescent bulbs make great options to ponder to provide the needed light. If the plant gets intense sunlight or you provide deep artificial lighting leaves show chevron-shaped markings that make the plant look even more attractive.
Ideal pH Level: pH between 5 and 7.5 is considered perfect for the plant.
