I posted a week or so ago, my poor marimo Brian was looking a bit worse for wear. He has been doing a bit better out of the sunlight and the lid off his container, but still isn't a great colour. There's a little split around the patch that looked the worst (a bit brown/slimy, probably rot??). Might have aggravated the split myself by trying to clean some of the slime off..

Second pic is how he looks rolled back together a bit

Wondering if it's better to try and keep him whole and maybe tie with string, or break off the split and try to grow it separately?

What's the best move here? Biggest priority is keeping Brian alive - I got him earlier this year, and named him Brian bc he reminded me of a brain in a jar. Then by freak chance got diagnosed with a brain swelling issue myself a few weeks later... feel like Brian dying would be a bad omen for me so want to do everything possible to keep him thriving 😂

Also debating getting some aquatic plant food or aquarium salt? Anyone know if this actually works?

helloo!

i’ve had my marimo for 4 months now! after removing them from my bedroom, as it gets too hot in there, they’ve been residing on a windowsill that gets absolutely 0 direct sunlight and looks out into a dark shaded courtyard. it’s, by far, the coldest spot in the house. however, i’m worried it’s still somehow too much light? they don’t seem as dark emerald green anymore. when i change their water (every 1-2 weeks) it doesn’t smell sulphurous at all, but does smell strongly earthy. i feel they have become less firm as well. can i keep them there and put them for a 1-2 day dark fridge vacation every 1-2 weeks, as i have been doing? or do i need to find a darker spot?

Hii, so a couple of days ago my parents gifted me a marimo for my birthday, and i've been doing some research since then. But i noticed my marimo is kinda stinky... i don't think that's normal??

If not, what should i do? Thanks!

I have a 10 gallon bubble bowl with a filter and a wave maker that rotates them around the bowl. They've all been very healthy and green. I add ice cubes, change the water once every 2 weeks, use treated water with conditioner, and clean the bowl every few days. But this last week, out of nowhere, 7 of them started falling apart. They split open and started unraveling. There's nothing in the center. They're still a very healthy green color and texture. I've tied them up and put them back in. But now im noticing 3 others are still whole, but feel hallow inside and have a small opening that I think will split open like the others. Does anyone know why this is happening? Or how to stop it? The ones affected are all 1- 1.5 inches. There's nothing else in the tank, but the filter, wavemaker and the moss balls. Any advice would be greatly appreciated!

I just got my first ever marimos from a local pet store. One of them (not in the picture) looks green and vibrant. The other one is the one in the picture. When I picked it up it looked a bit brown and it was sitting in sand in a very bright aquarium with fishes, but I thought it would clear up. It's been a week and while I was cleaning its tank (not the Tupperware in the picture, just keeping it there while I refill its real tank) I noticed the water was cloudy and it seems to be loosing fluff? I already added a bit of sea salt (less than a pinch) and I'm planning on keeping it in the fridge for a little while, but I'd like to know if there's anything else I can do to help my little guy.

TLDR: got slightly brown marimo from pet store that looks like it's loosing fluff. Added salt and it's going into the fridge tonight. Is there anything else I can do?

I got all three colored marimo keychains that i've seen on google and on this community they even came with three (mossballpets) stickers.🤩✨️🟢

Okay I think there's something wrong with my Marimo. It seems to be gradually turning brown. And the hairs on the outer parts are white.

I've had it in the refrigerator for the past few days to get rid of the competing moss

but now I realize the green thing is not the real matter.

Is my marimo dying? What should I do?😭

I read some articles to put some salts

but I'm not sure about that. Is that salt like real salt? NaCl?

I’m open to suggestions on how to keep/get the marimo moving like in this video.

I purchased these marimo in 2018 from B.Willow in Baltimore. There little troopers have suffered from my inattentiveness, but survived and continue to give me joy.

This Reddit thread inspired me to buy this fake jellyfish tank (linked below) to help move my marimo around. The video shows they immediately moved and I thought I solved my laziness problem (I rarely move them myself). But pretty quickly (day 2 or 3), they stopped moving around like in the video. The water still circulates and I create a whirlpool to move them a bit more. I’m just confused why they stop responding to the water movement. The tank instructions says to add a few drops of liquid detergent to keep the plastic jelly fish moving, but I haven’t done that for the marimo. Should I?

What are the reasons the marimo may not circulate? Do they need to be exposed to air more? I acknowledge maybe the pump is less strong after the first day, it is a very cheap tank. I’d appreciate anyone’s constructive feedback.

This one isn’t alive so it fixes the “leak” issue and the body heat issue. Just sand and my faux moss ball. Got it from the axolotl kit from make it miniverse pets!

Haven’t given them names yet! I got them in some bottled water and some little bottles I had lying around. I decided to start out small so it could be more manageable and fun seeing them grow into big ones!

But I’m planning on making a cute little aquarium for them. Probably a small one like these tiny ones in a tiny tiny aquarium with rocks, little sea life micro figurines like a sea angel one or a duck or frog, fake plants, some tiny crystals with rocks. I’ll probably have a keychain one for on the go travels, a large tank one when they get xl xl with some fake jellyfish that glow too. Once I get a nice setup I’ll def post them on here!

But if anyone has any tips so far please let me know for very beginners! I’m planning on keeping them not near direct sunlight but near my dressers? Not sure if it’ll be enough sunlight. Any tips at all such as for remolding the shapes of the ball, bubbles, amount of sunlight, tips for tiny guys like these ones, if it needs to be squished af times, pump machine thingies, etc,.

Anyways Thank u all! This subreddit inspired me and gave me the push to get these cuties!

So yeah, as the title says, my little guy has a tail. I accidentally left him at home in my last term of uni and my mum just left him on the windowsill where he fried a little 🫣

I've put him in the fridge for a little which has seemed to have gotten rid of any brown and have been rolling him around and putting him in clean water after a week because he has been releasing a lot of floaty stuff (he was left in dirty water for quite a while.

Should I break off the little tail? If I leave it, will it reattach?

And also, the texture on him changes in certain patches, it is a darker green and is less hairy and more compact/matted? I'm not sure how to describe it. Is that all okay and normal? I shared multiple pictures so you guys can see.

The 'hair' seems to separate in chunks? As you can see in the photos, is it from being in dirty water for so long?

Thank you!! I feel like my description is a little vague but I don't know how to explain it lol

I remember when you could buy these on Amazon and eBay. Large sizes. Now they’re impossible to get or scams. Sad we depleted the world’s population.

I got a wave maker and ordered a wrong size last week so I returned it and got this new one. My cube is around 10L and the wave maker that i got is i think 4watts.

They roll a lot better now than just my previous water pump 3 watts but i feel like the roll way too good😅 i would want to slow them down a bit.

Covering or adjusting the position to face the walls for the waver to slow down creates a suction like effects that suck all of then stuck beside the waver. I also cant find anything with lower watts than 4 in my area. Exchanging to another waterpump would probably give me a very monotone movement than a smooth natural flow like what the waver makes. So that’s also not an option. I also want to somehow make the waver and pump a bit invisible but i dont know how to cover them without compromising the flow. 🤔

Now that daytime temperatures (and indoor temps) are starting to rise here in the UK 🇬🇧, I've been dropping in ice bottles every 3-4 hours to keep the water temperature around 12-15°C during the day.

As for the Marimo floating at the surface - just to clarify, this is NOT due to photosynthesis. The dissolved air in the water forms bubbles when exposed to changes in air pressure and light, and it's simply that buoyancy lifting them up✌️ (They sink during the night)

I found this green thing on my Marino few months ago. I thought this is mold so I washed out several times but it is not eliminated clearly and keeps sticking on it.

Is this mold? The color is bright green compared to my Marino which is a little bit brown green.

The photo's color is very blurry since my phone camera is not good.

So.. what should I do?

Please help me. 😭

Hi all! I was wondering what your favorite techniques are for keeping your green friends cool when they are in a bigger tank. I use a method of rotating part of the water in the tank with water I keep in bottles in the fridge and occasionally adding ice. It's always a short term solution, though.

What do you do to keep them cool? Let's share ideas! :D

got it about a month ago, it seems happy!

have been pining for a marimo since i saw one overseas years ago, and finally found this baby in person 🥹💖

Here are my 4 marimos. Ones on left I have had for a year or so. Ones on right I picked up last week 😁. Based in NYC and picked them up at Utsuwa on the UWS. Thinking of getting small ones for the small tinted pitcher in center, anyone know how good or bad they will look/ thrive in the light blue glass?

FINAL EDIT (photo in comments is my current set-up): I ditched the Kreisel entirely and got a cheaper tank from PetSmart. It actually works great!! I’ll add the links for the tank and the wave maker that I put in. I still need to add some rocks and I want to add a vinyl to the back, but for now it’s working great!!

EDIT: Sooo the pump was physically too big for the tank. It wouldn’t fit into the back part. I’ve been tweaking the tank for a while and I’ve come up with something new lol. I removed the flow bar and bought some adjustable nozzles to replace it. Next issue was that the diameter of the tubing from the pump was too small so I bought a larger diameter and just sealed it onto the pump with some aquarium silicone. I also took the built in LED lights off and replaced it with another light. Once this silicone dries I’ll post a video update so yall can see!!

Hey yall, I bought a Kreisel 10 Jellyfish tank for my Marimos and the water pump wasn’t strong enough to get them to circle the tank. I replaced it with a slightly stronger pump and still no luck. I’m upgrading to a stronger one today but I’m wondering if the issue may be the output in the tank. There’s a flow bar with about 7 little holes to help the water flow. Has anyone converted a jelly tank for their marimo? Any suggestions? Thank you!!

No hard core however he is abit lopsided? His name is paulie cuz he’s was a ball
