I was canoeing in a local lake a few weeks ago and I found some very large anacharis growing about 10 feet off the shoreline. I scooped some up and brought it home. I put it in a spare tank with unheated water and an extra light that I had laying around. So now, the anacharis is doing really well, sending off new buds and growing long roots. I'm thinking about putting it in one of my tanks but I'm concerned about possible parasites or other unforeseen problems. Does anyone have experience or advice about converting local cold water anacharis to a tropical freshwater tank?
