anyone knows what the problem is?
What does it mean if my b. japonica is shedding leaves?
Over the past week healthy leaves from my blyxa japonica plant has been shedding. I found the reason yesterday when i saw an entire plant being uprooted. I realised that it was a node that split from another plant. I replanted the node somewhere else.
Now i'm beginning to see other leaves being shedding, presumably from another plant. what does it all mean?

You need to provide more info like your tank's parameters and dosing regime and etc for folks to help you. Otherwise, you would likely get a very general answer or no answers at all.

i have experienced the same thing too. Most of my plants leaves go melting away... leaving only a handful at the top.
Oh sorry.
My tank is a 9x6x7inches mini tank. Dymax hangon filter, Atman 7w clipon lights 7 hours, ADA amazonia gravel, B. Japonica, E. Tenellus and Fissiden on mesh. keeping endlers. water change weekly. Seachem Excel few drops every other day. Wondergro Micro and Macro few drops weekly.
To add, setup has been for a month. Apart from the tenellus converting to submerse form and fissiden growing slowly as expected, the growth of the japonica seems fine except for the splitting of nodes and shedding of leaves.

7W light... probably not enough light

might be useful to you. can browse through the website. not bad a web site actually.
thanks for the site. i've actually come across it before but i can't really relate to the problems stated there.
here is my theory though. Is the plant propogating? I did mention that i found one node being detached from the main plant, floated up in mid water and that's why leaves were being detached (detached from the bottom cos it's no longer in the gravel?) i have since found another node detaching itself from another plant.
anyone has further advice?
I think a better question would be what are the requirements for growing B. Japonica. I have this same problem before and have given up on the plant. Hope the the experts here can shard some light.

As Shadow has pointed out, it's very likely that the light is insufficient for the Blyxa japonica to grow. Further, B. japonica are nitrate hungry plants and as such it is also possible that there is not enough nitrate for it. However, I suspect it is more so the lack of light than nitrates that is causing the problem.
I'm not sure what the minimum requirements are for B. japonica to grow, but to share my experience: my tank is a 4x2x2 with about 3wpg PL lighting and pressurized CO2. I run the lights and CO2 8 hours daily and dose EI style with KNO3, KH2PO4 and Wondergro Micro+. I first started my tank with 5 sickly looking plantlets of B. japonica and 4 months later, I had more than 70 healthy plants with copper/gold highlights on their leaves. The growth was so dense that it looks like I had a thick wall of B. japonica in my tank. Hope this helps you somewhat.I think a better question would be what are the requirements for growing B. Japonica. I have this same problem before and have given up on the plant. Hope the the experts here can shard some light.
all right, for the moment, the two detached nodes i've planted them in another tank, and i've not experienced any problems with shedding of leaves in either tank now. i just hope all is well.
Hi Illumnae,
These are my tank parameters
Tank : 3ft x 1.5 x 1.5
Lights : 3x39W T5 (10hrs)
CO2 : 3-4bps
Dosing : EI method with KNO3, KH2PO4, Seachem Flourish
They still die off and my tank is also infested with BBAs. Looking at your tank parameters i suspect there's probably some problems with the CO2 level in the tank that's why the plant is not doing well and there's alot of BBAs.
BTW can B. Japonicas be grown in non CO2 tanks running with either 2 or 3 tubes of 39w T5?

yes it can grow in low tech tank, I have 2ft (15~16 Gallons) with 36 Watts PL light. It is about 2+ watt per gallon
What are the ferts or amount of ferts needed to grow them in non CO2 tanks? Do they need root tabs?
Admiring my Fishes calm the Beast within me
mine was 0 fert and 0 CO2, but added micro weekly after water change
ADA Aquasoil Amazonia, it grow very slow as expected from low tech tank.
I have the same problem with the shedding of leaves but no floating plants. I do noticed plantlets growing out from the side of the parent plants. One more thing i noticed is that my blyxa Japonica are pushing themselves out of the substrate exposing part of their roots.
Is it due to insufficient light. I Have a 2X36W PL for a 168 litres.

Your blyxa shedding leaves and BBA could be two different issues. Blyxa is not a easy plant. I manage to grow them in a non-co2, 36w, 2ft tank though. They are heavy root feeder and nutrient hungry.
Shedding a lot of leaves generally mean the plant (or one of the branch) is dying. Trim them. I noticed that usually those manage to grow roots in the substrate will survive, that means the lowest branch, and branches at the top usually melted away.
Probably the way to plant them is to trim them into multiple individual plant from a stalk which has multiple branches. Plant each of them into substrate, and plant them deep. Just my wild guess based on my observation and previous experience.
