I'm proud I've kept plants alive for this long tbh. One of them is a little torn, tried to keep him tied but it didn't hold well so he's free for a few weeks...

Marimo tank update

2.8k Upvotes

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. 🤔

7 Years Later...

Bought this marimo back in 2019 from a little souvenir shop in Sapporo, Japan — it was only about 9mm–1cm then (📷1). Today, seven years on, I moved it back into its original container for old times' sake (📷2).

Happy marimo keeping, everyone! ✌️

Do marimos get lonely

1.7k Upvotes

Sorry dumb question but I'm getting mine soon and just wondering if they get lonely if kept in a single one, I got two just in case but do they get lonely??? I read that plants have feelings so I'm worried that the algae won't be happy (Sorry again, dumb question I know)

“Bondage” time length?

I just recently got my Marimo there’s a couple of them that have become very loose and one larger one actually fell apart/exploded. So after seeing that a lot of people use dental floss to roll them up or contain them I’d like to know some more information about that and how long I leave the wrap on for. I am using unwaxed unflavored dental floss and I wrapped it in equally spaced wrap sections. Also since many felt loose I just did a mass treatment and wrapped them all. They are also in the fridge right now as it is very hot here this week, East Texas. I’ll include a photo and look forward to any and all help you have to offer.

Thank you

EDIT: Thank you all so very much! The comments were better than the intent of this post. 😁👍🏻🤭

Is he dead? 😢

I accidentally left him at home over the break and when I returned the water evaporated and he was bone dry, he's been placed back in water and on a windowsill with indirect light (but it's been very cloudy).

he's not smelly, stays together when I squish him, and maybe seems a little more green but I may just be coping...

please tell me mossisimo is still alive 😔

Got these guys for my axolotl’s tank in 2015. When he passed away in 2021, I stuck them in this jar as a memorial and they’ve been on a shady bookshelf ever since. I’ve never changed the water but they’ve gotten bigger and seem to be happy ¯_(ツ)_/¯ ft. bonus axolotl content from about a year after I added the marimos

I left my marimos alone for 7 months and came back to this

I barely paid attention to my marimos for about 7 months, and somehow I came back to find that they had all become fuzzy 🤡

Part of the reason I disappeared for so long is that Reddit is blocked in my country, so I have to use a VPN just to access it 😭

The first photo shows two marimos I made myself, and the second photo is what they looked like when I made them on Jan 27.

It’s been about 9 months, and I genuinely have no idea how they became this fuzzy 🫪

New tank set up

1.2k Upvotes

I bought a fairly inexpensive acrylic tank that has a basket on one end meant for plants. I've recycled a thicker can that I just fill with some water, let it freeze and pop in the basket to keep the water temperature cooler. I'm on the search for maybe a cuter container to use in place of the can, but it fits perfectly. 👌

My jungle tank full of marimo. The big middle piece is driftwood I scrubbed a moss ball along until it left tiny little strands on it. Three years later I got this! I started with four tiny moss balls in this tank.

Almost ten years with the big ones!

I've had the big ones since before 2018 (I think 2016 but for sure 2017). The little ones I got in 2020. They all started off about 1/2 inch diameter.
They have gone through various containers in that time, not completely happy with the one that they are in right now! They really like the current set up it seems.

Found a snazzy new home for Maru-chan

First time poster! I got this marimo about a month ago and he originally came in a smaller, lamer glass bottle.

I found this new one in a store in Sweden yesterday and thought the spherical cork stopper was awesome and thematically appropriate 😄

Also got some glass beads for the base, but I’d really prefer little glass balls without holes in them. I don’t even know what they’re called though, let alone where to buy them 😅
