No moss, but I do have a mat of Riccia floating in my tank that I could send you a chuck of. It would be about 4" x 8" x 1/2" thick. It's fine as a floating cover for your fry, but if you intend to use it for decorating you'd need to pick out so embedded debris (leaves and some bits of algae).
PM me if you're interested. It would be $4 for shipping. |
