Riccia Fluitans Mini Tissue Culture Cup Live Aquarium Plants Carpet Fish Tank   4 oz cup.
Riccia 'Fluitans', also known as crystal wort, is an aquatic floating plant of the liverwort. It is common to be tied or glued on to a platform such as driftwood or stones. A traditional floating plant offers good protection for young fish.
High lighting and Co2 injection are necessary to keep this plant low growing. Vertical growing thin stalks are an indication of lack of lighting while yellowing leaves can mean nutrition deficiency. Thin leaves can also hint at a lack of Co2. This plant can grow quickly and require regular trimming when kept under proper conditions.
This plant can grow submerged or emersed in dry start aquariums and Wabi Kusa. Because this plant is small with tiny roots, it can prove difficult to keep planted into the substrate. In this case, dry start can help by allowing time for the roots to anchor into the substrate before flooding the tank.
Remove tissue culture gel before planting. Simply wash the gel away or soak the plant in water and squeeze the gel off with your fingers.
