Best floating plant

I want a floating plant for my 29 gallon covered tank that has all of these components

Floats
Has long, thin roots
Can take a medium-high current
Can stand medium-high lighting
Won't take over the entire surface (duckweed)
Doesn't mind my dwarf gourami nibbling on it from time to time (to make his bubble nests)

Thanks in advance

 

Water sprite can be grown planted on the bottom or floating free .It is very easy to grow.

 

I was thinking something like amazon frogbit, but I tried them and they don't seem to like the current from my filter.

 

I heard water wisteria is a good floating plant!

 

Would water lettuce get to big for a 29 gallon tank?

 

Water lettuce tends to stay small in indoor tanks. It does eventually take over the surface if you don't thin it out, but the same could be said of most floaters. As others mentioned, wisteria and water sprite are good options as well. I like red root floaters the best personally.

It should be ok. I have some in my 55 gallon tank. Roots got a foot long at one point, when I had little flow across the top. Then I had to medicate tank so increased the flow, added carbon, and hasn't grown as quickly or with long roots either. Now roots are a couple of inches long.

 

Will water wisteria, water sprite, and/or red root floaters Thrive with a High flow?
Also, I want roots or leafs (preferably roots) that will hang down at least 4" (preferably more)
I just don't want to go buy more plants to have them die/not grow in my tank.

 

Another question (sorry)
I saw somewhere that penny wort could be grown floating? Is that right?

 

Yes, pennywort can be grown floating and rooted.

 

(When floating) can I just cut pieces of it off (when it starts to get too tall/long)?

 

Yeah you can, in fact I'm pretty sure trimming is encouraged as the plant grows back brand new growth, it's just generally good for the plant. Plus it keeps things nice and tidy.

 

Is there anything that grows as fast as duckweed (or close to) but is bigger? Not that I'm not getting the pennywort and don't like your suggestions, I was just looking at different options

 

I made a little ring out of airline tubing for my frogbit to deflect the flow. Now I have Frogbit-Palooza!

 

Water lettuce is great but it needs an open cover or lower the water line. I have 5 in my 75 and they are doing great. I also mist them twice a day to keep it humid as possible

 

How about Salvinia natans?

 

I have a couple of cabombas(rooted) in my Asian tank and they grow super fast(reached the surface in a month or so), can stand flow and can stand the lighting. Will that work for you or you need a floating plant?

This is perfect
I love the look and the roots, thank you

I'm actually looking for a floating plant for this tank, but this seems like a good plant for my new Quarantine tank
