I got mine from
www.floridadriftwood.com more than a month ago. They are
just a 3" green ball that occasionally moves around the tank when the
bottom feeders hit it.
Speaking of bottom feeders...do algae eaters eat this algae? Would I have
worry about my snails or SAEs or Amano shrimp eating it? They sometimes eat
the java moss, but so far, it's growing faster than they can eat it. I'm not
sure Cladophora would.
