It depends on the tank. If you have good lighting, it'll grow anc cover the surface of the entire tank. If you have a power filter, it'll be pushed down and get caught in the filter intake, so it can be a pain.
If you have an undergravel filter, it works better. The fish won't necessarily eat it, but as it covers the surface of the water, it can reduce evaporation (but also oxygen/carbon dioxide exchange a little). The roots that hang down give some protection for guppy fry, and it becomes a good area for microorganisms to breed that the fry can feed on.

I love duckweed in one tank if I have rainbows in another. Rainbows tear up duckweed like it was the best thing ever. Silver dollars are the same way. It is a nice free food for herbivores. Guppies probably won't eat it but many tetras will.

I think "ugly" is subjective and a matter of opinion. I, personally, think it's beautiful, especially in a pond and I purposely put it in my pond. And goldfish and koi adore it! You can't keep it in the pond but for a few days before those fishies will chow down all of it! But, for tetras and guppies, no, this isn't really something that they will eat, nor most other tropicals and it's not great in any aquarium that has a filtering system with an intake. Yes, duckweed is really only going to work in an undergravel filter system, even if you have fish that will eat it.

Not really. It's not really bad, but it's definitely ugly to look at, and neither tetras nor guppies will feed on it. Typically, duckweed gets into aquariums as kind of a 'pest' plant, frequently from other live plants. If I remember correctly, goldfish and carp (or koi) will feed on duckweed, but you definitely shouldn't keep any goldfish with your tetras and guppies.

Yes. It will provide a hiding spot for the fish and allow the fry to escape from being eaten. It is also called Anacharis and Elodea. It may require a little trimming every couple months because it grows quickly, but it will not overrun your tank.

Trust me on this one. DO NOT GET IT! even a tiny bit of it ! I had a tiny patch in a bag that some of my butterfly koi came in, it took over my entire pond in about a week, and the more I removed the faster it grew...I had to completely tear down and start over...I would look into getting something else if I were you.

no way. first of all it spreads all over your tank even if you just get a tiny bit of it. second it is very ugly and fish dont even care about it. third it produces more algae and that could make the fish stressed or kill them.
