My local (disused) canal has a lot of what looks like duckweed and frogbit in it, it also has a healthy fish and fowl population. I'm getting some new fish soon that will definitely need floating plant cover and am wondering if I could use these out of the canal in a tank? I could 'quarentine' them first and the temp will be around 25deg - I could bring the plants up to this slowly while in quarentine.
Can anyone see a problem with using them at all?
