Frobit or Duckweed????

Looking for a floating plant for my 5.5 gallon betta tank. Marimo are the only live plants I have. The current floating plant is fake and just used to shade the marimo and provide my betta with some cover. Currently running a compact 6500k cfl from lowes for 12 hrs a day. Dose the tank with flourish comprehensive once a month and change 50% of the water 1-2x per month. What are the pros and cons of both plants? I've heard that frogbit is prone to rotting of the top of the leaves get wet and the duckweed can take over a tank and get caught up in the filter. Any experience or other suggestions is appreciated!

(If it matters at all, the tank has been running for over a year in its current state)

I don't know if there's any other floating plant that grows as fast as duckweed. Given the right lighting which you should have, it will grow pretty quick and will even flower. Oh and it has beautiful red roots as it's name implies.

I have spirodela polyrhiza- the 'greater duckweed' in my betta tank, and I actually like it. It doesn't grow as crazy fast as the smaller duckweed, and is easier to control. I only have to scoop out one or two handfuls per week to keep the growth in check. If some leaves are dying off it's easy to pick out individual plants- I never could do that with the regular duckweed- and it doesn't cling to everything like crazy, either. Easy to brush off back into the water if you get some on your hands.

It shades my tank nicely enough that I don't have algae issues in here anymore.

I have a 5 gallon betta tank and the duckweed easily gets out of hand every couple of weeks, to where I have to scoop huge quantities out. I like the way it looks but it does tend to block a lot of light for my carpeting plants. Might not be an issue for those marimo though.

Right now, I'm really loving silvia minima and dwarf water lettuce

I was thinking the same thing. Generally is it the red colored plants the require more Iron based ferts? Correct me if I'm wrong. I would rather not change my ferts....my tank is simple and easy as it is now and I don't need to start getting algae blooms by chaging my dosing.

I think I may just order some duckweed off of Amazon since it is so cheap or try to find someone on here that is selling. Seems easy enough, and I really don't mind scooping some out once a week or so.

Nope, I used to have it in multiple tanks with no co2 or ferts and it flourished.

Nice! I always thought they needed decent ferts. Now you are making me think about getting some for my work tank...

I think of all floating plants that we use as super low tech. They don't really require much, it's like growing Amazon swords or java fern.

RRF or Frogbit, never ever duckweed.

I have both frogbit and salvinia on my 12g betta tank - a nice mix of leaf shapes and short and long roots.

I love my frogbit. It multiplies just fast enough to keep things interesting, but slow enough that it's easy to maintain. It's also much easier to scoop up to give away or throw out than duckweed, imo.

Once upon a time I had ludwigia. It disintegrated.

Frogbit over duckweed every day! Duckweed just gets everywhere and is a pain to manage, duckweed is much larger and easy to remove / thin out
