I stumbled across this subreddit, was suggested it. Intrigued by the what appeared to be a mossball but is actually a marimo. What is a marimo? I saw in the community rules it is an algae, but what else about it? How can I acquire one or more of them?

Took years to get this big. It sits in a cool spot and gets rolled every few days.

3 gal bowl, no filter, 2 pumps, 70 Fahrenheit

I’m attempting to revive what’s left of my neglected marimos with this setup. Should I make any other adjustments?

I got gifted these two small marimos, they came with pebbles, some plastic seashells (glow in the dark as well I think) and these marimos with small figures.

The marimos were in plastic bag a little damp but I’d say dehydrated, so I put in water for 20 mins, after squished them, and there’s no hard middle part as some here tell about. One even showed a hole from side as if it was gonna break in half, but I rolled it in my palm.

Also when I was first squishing them - I might’ve been too soon and these bits came out of it. But this is all that came out of the marimo, no dirt.

First photo is 20mins after introducing to water, the rest 12. I really wanna know if these are real?

I just bought a moss what do I do with it

I want to buy a marimo because I got really in love with them. I live in Spain and want to buy one.

I'd been searching for a week places where I can buy them online (especially EU or Spain shipping), and I found this webpage called "Slow Botanics" (https://slowbotanics.es/) that they sell marimos.

On the webpage they say they include with each one the "European phytosanitary passport and certificate of authenticity", but I'm very skeptical.

Can some of you confirm to me if these are real marimos by the pictures?

A store sold me these, saying they were a few years old and are real. I got them home and they feel hard, like something hard is in the middle. One of them floats! I called and asked if they're supposed to be like this, and was told that they are supposed to have a hard core, and the floating one could be poked to make it sink. Are these things even real? They were $21.50 EACH. Feeling ripped off..

UPDATE: You guys were totally right! These were the fake filter balls! The manager insisted they were real, but ultimately allowed me to return them! He was not pleased. THANK YOU EVERYONE FOR YOUR INSIGHT!

This marimo is almost 2 years old, got it from s friend as a Christmas gift. This year has been exceptionally hot - heat waves from May to August brought exceptionally hot temperatures (even above 30°C) so the marimo suffered even if it has never been exposed to direct sunlight. I think it's still alive since it's still green, but it's paler and a bit slimey in some parts of its exterior. Three months passed but it doesn't seem it's recovering a lot. Is there any way I can help it?

Also, do mosquito larvae damage the marimo? They colonized the jar one year ago and while I saw them eat debris on the jar and some parts of the marimo I thought they could help clean it, but maybe I'm wrong. I clean the jar more often in any case due to the debris they leave.

I bought 3, used the best for the marble setup then split the others into 5 separate pieces. Thinking a shrimp or snail tank for the 5? Didn't know these things even existed until seeing this sub. Thank yall for the inspiration.

Hi, I had my moss ball for a while but lately i left it next to a sunny window, and the outside turned grey/white. I looked at the interior, which was still very green and rolled it back up. Do i need to remove any white parts or will it be fine ?

What did all of yall do yesterday on saturday while caring for y'alls marimos?🤔🟢🫙

His name is Midori.

Wrapped him up in thread cuz he's falling apart a bit.

Hello! So these little bits came off of my main (very large and round and healthy) marimos, and as you can see, they're not "moss balls", they're "moss clumps". I have kept them in a glass container with cool fresh water, I rinse them and squeeze them and tumble them around manually. I keep them in a semi dark environment, with a little bit of light. But they will not become BALL

So in lieu of this, I bit the bullet and purchased this little cheap "jellyfish light" that tumbles these little silicone rubber jellyfish around. I pulled the jellyfish out and cleaned it and put established fresh water into it with my moss clumps. They tumble for a minute but then just kind of get stuck somehow and sink, and I think the water flow isn't strong enough.

Does anyone have experience with a similar sort of device and know of a way I might go about turning up the water flow/pressure? Something like instructions on what to change when the pump is opened up manually and maybe a way I can adjust it that way? The button on the front only has two modes: slow and slower. I had been hoping that this would tumble them and make em ball shaped again!

Anything helps, thanks!

Note: light on for a better pic

Note 2: here is the exact thing I bought here

So I’ve had this Marimo for a few years now, do you guys think he would benefit from a bigger jar?

Hi.

I have this marimo from nine years, and now I'm trying to take care of It a Little more.

I took a larger glass jar last week, i changed his water today and when i put It back i noticed a hole.

There Is something i can do?

PS: english Is not my native language, sorry

So I have three moss balls I’ve kept for years, I got them from petsmart and they’ve been doing pretty good but I’m not the best at caring for them. I want to give them away but know nothing about shipping so I’ll probably have to give them to someone in person. I live in Kentucky so if anyone wants more details feel free to ask.

This how it looks after 1 week. I think it grown up a little bit.

Ive cleaned all of this several times, but the spots keep reappearing. At one point, they even spread to other marimos, but after I rinsed those, the spots didn’t come back

I googled for some information and found out that you can put them in the refrigerator to stop a algae from spreading, but I’m not sure if i should really do it

Ive had them for about a month so I’m a beginner when it comes to keeping them

😭😭

Sorry for the poor quality, i dont have any new pics of this oroblem yet, as I only just recently cleaned the marimos

They are kept in clean water, but I used to rinse them under tap water

I have some suspicions as to why this started, if it really is some kind of algae, and I’ve already changed the conditions in which they are being kept
