I think it would be a little tedious to remove the string, coz once the moss starts to grow, they will attach to almost anything they touches, so I would rather leave it as it is......but I think in the end it would come to personal preference either to leave it or remove
Here's one of my early moss on bogwood (this one is java moss)....once it starts to grow and spread, the string is totally covered. Same goes to the Java fern above
Thanks for the compliment aunt
Let's see....according to aquamoss.net...the scientific name for spiky moss is Taxiphyllum sp.
Aquatic Moss. How to grow Aquatic Moss. Info on Java Moss, Christmas Moss, Taiwan Moss, Peacock Moss, Stringy Moss
and I got the moss online from local hobbyist....haha, I've been obtaining my plants this way, ordering online, coz my LFS don't have much variety
