Amazon Frogbit...what The?

My honey gourami eat duckweed (leaves and all) that's floating in my tank. .. So I'd bet they're the culprit for your missing plants.

I see hit contains Fe but I wonder how much.
My bottle says 0.024%

Could lighting be the problem?
 
Some time ago I've saved this on my computer, maybe it would be of interest to you as well:
http://theplantedtank.co.uk/deficiencies.htm
My light is an Arcadia Fresh Water Lamp 25w, 750mm, 30", It says:  high light output (true, I've had to make a shade because of algae), shows rich greens of plants, brightens natural colors in fish, encourages plant growth.
 
Thats what the leaves of mine look like when I'm not dosing enough!!! With maybe a tiny bit of yellow sometimes...
 
How long are the roots on th frogbit? Are they producing any shoots and forming new plants?? If the answer is no, I would say ferts, ferts, ferts :)  Maybe try dosing a smaller amount everyday? or switch to a different brand.
 
Even if your gouramis are nibbling away at the plants, if they're not getting enough iron then they won't be able to grow their roots back fast enough, and I would imagine that could cause the leaf melting too. Kinda a vicious circle :/

Maybe worth trying to give the gouramis a few veggie tabs once a week or something too! I feel your pain, my polka dots turn my swords to swiss cheese :rolleyes:
 
The roots are disappearing except for on one that has a really long root, probably more than 6 inches.  I have two little plants forming... but at the rate that they are disappearing that isn't much!
 
My fert says weekly and to not overdose... so it makes me worry about changing that in case it isn't safe for the fish.  Maybe I will look around for something else to use for a fert.
 
I started with seachem flourish. I started with 5ml a week, then changed to 2ml a day, then i went to 3ml a day lol. If you're worried about a reaction from your fish, it's always good to start with smaller doses and work your way up :)

Could it be shading too much? I have a full spectrum light that came with the cover, not the best light, and don't have much luck with floating plants either. Mind you, the gouramis are doing their magic on the roots as well, lol.
 
I don't think it is too shaded. My bulb was REALLY bright... I was getting brown algae everywhere... had a blue shade I made previously that faded... then when algae returned and brown hair algae started too... I used a very thin white plastic table cloth as the shade instead (took the idea from the person that said they just use white paper) and it has been working a charm.  It is of a similar brightness now to the tank next to it (which has a different bulb).
 
You know what... I'm going to put one frogbit in my other tank and see if I can get them growing there....
 
That sounds like a good idea, it will be interesting to see if there will be a difference.
 
About the shading, since the light the plants use are specific in the spectrum, I was suspicious if the shading you are using may be filtering out those spectrums of light. Not that I know a whole lot about this, but from what I understand even glass and the water itself already does block/filter/reflect(?) to a certain extend.
 
Hmmm, I don't really know about that either.  :/  My other plants are doing beautifully though (java fern, two types of anubias, moss balls, java moss).  My anubias flower every other month.
 
The person that sold me the frogbit said that they prefer med-high light and do best with proper ferts.  Java fern, anubias, and mosses all do well with lower lighting.
 
I think the ideal situation would be getting the frobit to really take off, then you could take the shade off of your light, and the frobit would still provide enough shade for your other plants.
 
I agree that it will be interesting to see how they do in your other tank. I would think that getting the roots chewed off would have a significant effect on the plants... hmmm........ i guess we will see :)
 
That was my idea... to use the frogbit as a natural shade.  If it is an issue of lighting then I probably have a problem... if I remove my shade then my plants end up covered in algae!  I've already reduced the algae by probably 75% now.
 
So far to good with the one frogbit in the other tank... though I did see my betta give it a nip but didn't seem to eat or break any of it.
 
A little update on my frogbits.
 
ALL of the plants in my honey gourami tank are gone/died.  All of the ones I moved to my betta's tank are still alive but have had next to no growth, but no further declines.  My betta likes them quite a lot, he likes to swim under them and blow bubbles.  At this rate... I will never manage to spawn enough to cover the top of my honey tank!  LOL
 
If the gourami is eating them then you're out of luck there. I have mine under bright LED lights and I have to remove half every couple of weeks so the tank is totally covered and the roots need trimmed every few days. I don't have anything eating them though.
 
Mine grow pretty uncontrollably too, like I'm throwing them away lol. And I have 1.5 wpg.
 
If they're not doing so great in your betta tank either, I would say it's got to be ferts. They just need more than what you're giving them. If you're looking for an easy-peasy basic fert that does the job, I would suggest Seachem Flourish. That's what I started off with, once a week, then I moved to dosing daily with it as well.
