I like frogbit, though any floating plant requires regular removal to not cover the tank. I have a piece of fishing line on top of my tank to try to keep the frogbit in one area, but some always get out.

I also like frogbit. It grows pretty well for me, and it's fairly easy to control by periodically removing a few plants.

About the only real drawback I've noticed is sometimes if it's disturbed, it seems to shed it's roots. then I've got gross little rotting strings all over everything.

Now, whenever I do something I think is likely to trigger this, I just manually remove the roots and drop it in, they grow new ones easily enough.

My clown killies seem to like swimming around in the roots and stuff, so there's also that.

So you can just trim back the roots as needed?

I like my Salvinia minima because it's small and neat. Doesn't have long roots, which I prefer, but might not be what you're looking for.

I agree with frogbit and salvinia minima. No duckweed, whatever you do. You'll be picking that stuff out for the rest of your life. I've managed to keep it culled in my tanks but it requires a lot of effort on my part.

How about a tiger lotus or banana plant? In a lower light set up they will send floating leaves, easy to manage, provide some shade, and height. Also, some val will do well and provide the height you are looking for

I use wisteria in my tanks with more flow such as a hob filter. I found most true floating plants get blown all over.

I have banana plants in 3 of my 4 tanks and never got one to send leaves all the way to the surface.

Red root floaters are pretty cool, but it you're looking for something that doesn't block too much light Hornwort is great, no roots though. +1 on Salvinia but it will cover the surface quick and shade things unless you remove it weekly.
