Willow Moss can be left in your aquarium to roam around in the current until it finds a natural place to rest. It will attach itself to bogwood, roots, stones an many other tank items. You can also manipulate where it is to grow by attaching it to items within your aquarium. For example, you can use fishing line or similar to tie it to bogwood or rough stones. After a couple of weeks it will have grown into its host and you can remove the line. You can also attach it to corks (from wine bottles or natural decorative bark) in a similar manner. This provides valuable floating shade or retreats for your shrimp adults and babies. Does well in most tank conditions and normal lighting conditions.

Sold in a golf ball size.
