Süsswassertang. Size of clump will be two large handfuls. Great for shrimp tanks as well as fish tanks. Grown low tech in my shrimp tanks. Common name: Süsswassertang, Lomariopsis Lineata, Loma Fern, Round Pellia Süsswassertang, also known as Subwassertang, is an aquatic plant that is a great addition to any planted tank, especially shrimp tanks. Although it is slow-growing at first, once the plant is settled, it will grow well and is a great way to provide natural coverage for different species of fry and skittish fish. The plant also helps to neutralize toxins in the water column while promoting oxygen-rich water. Subwassertang grows similar to mosses and will self-attach to driftwood and stones. It can also be left free-floating. Because of its easy-care nature, this plant is a popular choice for beginner aquascapers. pH: 6-8 Care: Easy Light: Low to medium Co2: Not necessary Propagation: Cut or Rip
