I am working on setting up my first shrimp tank and everything I have read says that shrimp love moss. I was leaning toward java moss, however when looking for some at my LFS the owner told me that he considered it a weed. From his experience it grows wild and will choke out other plants. I was unsure about this, but wanted some other opinions. Also, is there a better moss for shrimp? I am wanting to start with yellow or OEBT.
