Duckweed....

[marisa]

Those little floaters (tiny green circles with one tiny root below the water) are called Duckweed right? Well anyways....

I noticed when I put plants in my new little ten gallon (thanks for the plant help shane and coor!) that some little duckweed sto-aways had come home with them. Last week I had exactly four little ones floating. Today I have double that. Maybe even triple. Not a lot, I know....but obivoulsy they are growing.

Do aquarium hobbyist consider them a pest? How many can I safely let grow before they take too much light away from the bottom plants? I like them and want to keep a small group growing.

Thanks for the help as always.
