Trust me, my two tanks have them. My 29 gallon has the MOST, and my 10 gallon, the duckweed doesn't grow much. Mainly because I have an incandescent light bulb and it's not very strong on the light along with the Kelvin rating. I've got floating water sprites too. So I might have to take them out from my tank and bury them under the soil. I don't know if that would be cruel, but I've got a whole bunch of water sprites that are like having new ones coming out all the time.
I might have to use lead weights to keep my cabombas together too. Along with my water sprites. Although i don't know

People say that the leaded weights aren't very good for the plants. Especially if you have them in for a long time I hear that they will cause the plant stems and roots to rot. I don't know if it is true, but that is what I heard :S

I heard the same thing too. At Pet smart, the workers put goldfishes inside all of the tanks (except for the aggressive cichlids tank) to eat the snails up.
Although since I have a pure tropical fish tank(s), I can't put in a goldfish because they might release some chemical into my tank killing the tropical fishes. Big Al's said that "goldfish and only go with goldfish" but I don't know if that is true. I've kept black skirt tetras together with them before along with glow light tetras. But I don't know, I was just doing some experiments with the fish compatibility. Mainly because I lived in Waterloo, Ontario before and at Pet Cetera, they said that you can put as many fishes as you want in a fish bowl (I didn't believe it) and they also said that tropical fishes cannot go with the goldfishes either. Although in the past, I found that a few fishes can withstand the toxic stuff that goldfishes release in the tanks.
Although I don't do it anymore. I don't want to spend a lot of money on fishes that may or may not survive, but I always have a spare tank to keep all of the fishes that aren't feeling so well in the tank in to a different tank.
To be honest I kept an oscar with my large fantail goldfish before, and it survived. Although it grew big and I had to take it out of my tank.

My tank's water current isn't rough though. Only when the water gets low, then the place where the water exits out of the filter to make a waterfall comes down into the water, and then my duckweed gets forced down under the water, and then they just float back up again. Although during feeding time, my black skirt tetras and other tetras and/or angelfishes go after duckweed mistaking it for fish food, and they just eat the stem (those small things that are under the duck weed "umbrella" like thing I guess you could say it xD) So then I might have to just start taking my net and taking the duckweed out and digging a hole in my garden and throw the duckweed in there, and then I can just let the earth do it's thing.
Turns out my strawberries and tomatoes are very nice and grow very big and red/orange

I see. So where is duckweed originally from? Asia? South America? Africa?
