If no photosynthesis how it can maintain it's greenish color leh? Anyway i'm not expert but since it only grow so little per year so i can only say its process of photosynthesis is slower than normal plant as it doesn't need much sun light. Mine i placed in the bathroom most of the time and it were so so green like in Dark Greenish color so healthy.
So it's good to hear from a marimo fan here that concern about their marimo but as long as they are healthy you no need to concern about what to see wif naked eye lah hehe

ewwww... y ur marimo look like very yellowish in the Day 3 photo????? mine marimos all dark green n healthy healthy.... yellowish meaning already sick right???

i read from other site about the grade A and B marimo, they say the facebook seller is a cheapo and money sucker..... the grades are just to cheat beginner marimo owners according to what they say.... guess u gotta be careful when the seller say their marimo are grade A marimo.. RM80 for Nano nehhh.......such a money suckerr seller....... (a facebook seller konon... more like scammer)..... if want get marimo u better buy from our lowyat dai ghor marimo seller leeyung.... sure no regrets.....

Is it posible to ask the seller since they are the only one knows the originality of their Marimo. Anyway the curing is not a one night thing, it may take months. Having Marimo in a small bottle as key chain/ hp strap is not reliable at all in my opinion. The bottle so small, the chances you'll let it expose to sun light, the water contain in the small bottle are so so so little( as in summer it requires water changing more frequent). There are some even find that they smell when they open the container to change its water.
In short, you need to ask the seller if they possible to help you.

as long as it is not in the freezer should be ok. but remember to take it out over nite. i once left my momo in the fridge and forgot about it. when i realised, the whole thing turned brown d. T.T
even though they love chill places, but they oso need light. i guess i accidently left them in cold darkness...

erm, i thought whole thing turned brown means... died? >.<

wow........20C air con room sure good for then. mine also i put at 23C air con room. guess they love the coldness!! hope your yellowish get well soon ya!!

Hi all,

I'm a long time fan of Lowyat (the building) and now a proud marimo owner. I've been away from Malaysia for 7 years but I manage to visit that place every time I come back xD

Anyway I just wanted to say thanks for making this thread, it's a great source of knowledge for me (and many others I'm sure), and to introduce my family.

This picture was taken a few days after one of my 2.5cm marimo "died" and fell apart. It endured three weeks in the postal system before arriving here, along with 10 other similar sized marimo that all got squashed and a little browned in the process.

I read everything I could find on the net before handling them, but nothing beats experience 

In the interest of returning them to nice ball shapes, I was a little over-enthusiastic in rolling and squeezing them between my palms. The water came out brown the first 2-3 times, and then tufts of fur. Lots and lots of brown gunk floating around, even immediately after I changed the water and cleaned them.

After that I noticed two of them had "pacman'd" I quarantined and fridge spa'd one of them, but it was too late, it just kept falling apart. So I took the individual pieces and rolled them back together into nanos. They pearled and floated, then landed on top of each other.

Do you think they're trying to get back together?

Go do the frog dont do on your baby mairmo 

Really don't recommend it. From what I've seen/read it's very difficult to get the fibres to close back up.
Thanks!
Thanks!

Try hitting all the right conditions for the marimo; roughly 10C water (you can store some in the fridge), LOTS of light (I use a strong LED lamp that puts out very little heat), agitated water (I just shake  the container or full blast tap water to get some air into it), and a pinch of salt.

Hey Fox, I think others will be able to answer the questions better than I can, but I have one piece of advice for you - start simple. Focus on giving your marimo the right kind of water and light first. The simplicity is the whole point with marimo! Unless you're an experienced aquarium owner, it's difficult to set up the right conditions for even just one type of organism. Put simply, if you decide to throw in more plants, fish, you're very likely to encounter deaths in the tank, which will then turn it into a very hostile environment for everything inside it unless you clean it up well. If you have experience or want to go ahead and try anyway, please ignore this ^^

But, based on what I've read:

2. Normal non-iodised salt will work. Leeyung says special "marimo salt" aren't anything special and just grossly marked up regular salt.
3. The fridge is for temperature, the darkness is to eliminate fast-growing unwanted algae that thrive on high amounts of light. Since the fast-growing algae have high metabolic rates, the lack of light will quickly kill them off, while the marimo is adapted to low light and grows very slowly. Use these parameters according to the state of your marimo.
4. Everywhere I've read says *any* artificial light will do, even your ceiling light. Just avoid direct sunlight, it's the #1 mistake owners seem to make. Whatever your light source, make sure it doesn't put out a lot of heat, or you could bake your marimo. Leeyung says high amounts of light encourages pearling.
6. Leeyung says use a filter, which cleans your water and incorporates fresh air into the water through agitation. The increased CO2 will encourage photosynthesis, which leads to more pearling and more rapid growth.

Good luck!

Hello Azure Fo
Your tank looks very big. Much bigger that describe by you as 15.5 cm by 15.5 cm. Better be quick in getting in the filter and some fish in. Then your tank will be very vibrant, fill with movement and colours. 
By the way, what is the size of your Marimo?? Looks like Giant or Super Giant from picture. And how many did you get from LeeYunG. I can count about 10 of them. 
Good work, keep it up 

Please pardon the website, but I'm set on buying this HOB filter. I've seen many people recommend this brand above all others. Could be a bit pricey to pay in ringgit though

The brand also sells all kinds of filter medium. I'm pretty comfortable with their range.

Damn, leeyung's marimo look flawless.

I tried to use gravel in my tank as well. After washing it for the 3rd time, I gave up. Just not worth the trouble, so now all that's in my tank is marimo and water, and I'm finding I quite like the look anyway. Makes cleaning easier too.

However, if you're set on using gravel, you could ask an aquarium shop to sell you existing gravel from their tanks. I did this once and boiled the gravel just to make sure I didn't import any nasties, and the water was clear.
