r/Marimo

This is my first Marimo. Their name is Green Pea.

Their first 5 years were in a jar, the last 10 in my aquariums. They got lost among my plants and I just pulled them out yesterday so they are looking a bit rough. Normally their hair is shorter and tighter.

I’m confused. I’m finding conflicting information:

- cork stopper or glass/plastic/aluminum lid?

- screw-top lids or airtight seals?

Ordered them off ebay last year. They were more clumps than balls, and fell apart into these small chunks of moss that I reroll by hand every now and again. I kept a few in a small glass bottle at work and would roll them around every morning, and they kept their round shape. I've since given that bottle to a friend so I don't know what became of them.

I haven't really cared for them this past year (kept them in a closed jar on my nightstand) but I've vowed to start now. I've ordered a small aquarium pump to help roll them around, I am going to give them ice every now and again, and I will move them outside in the winter. Currently, the nightstand is the only option, but the light there is limited. Is there anything else I can do? Tia!

A few people on my last thread asked for tips, so here's the short version.

My method differs quite a bit from what most other users or shops recommend:

• Lots of natural light
• Indoor light/grow-light LEDs don't cut it
• Cooler water — not icy, but around 12–17°C (54–63°F) most of the time
• Never above 20°C (68°F), or bacteria inside the marimo become active
• Tap water's fine — safe for you to drink means safe for marimo
• Skip salt/fertiliser entirely — it just feeds unwanted algae
• Don't house it with other aquatic plants or animals
• Use a tank of 10L (2.5+ gal) or more — the small container it ships in heats up fast, like soaking in a hot bath

Good luck!

Tem uma semana que eles chegaram aqui em casa, hoje fui fazer a troca da água e estava com cheiro de ovo podre, o que posso fazer para eles melhorarem?

-usei água do filtro, lavei bem os recipientes, a viagem deles foi longa (China para o Brasil).

(Foto em que estão todos juntos foi a 7 dias, quando chegaram, a outra é de hoje).

I also am going to refill its water, I know it’s getting a little low due to the cork

Hi! I’m new at the hobby and I got a couple of Marimo moss through Amazon. I was told to let them soak and they will recover their green. I don’t think this looks ok. Any ideas where I could find Marimo moss in Portland, OR? Thank you in advance.

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! ✌️

Usually they are not against the window so much but in the ledge slightly below but they rose to the top and formed these I’m not sure when…

edit: Sorry for being an idiot guys but I’ve never seen this before but it’s exciting to know

First two pics are how he looks now, the others are from last year. I know temperature is probably impacting him but I try to put him in the fridge. Also trying to figure out a happy medium for sunlight. He looks sad ): any advice?

Hi everyone im new to taking care of moss balls and im loving them so far. Ive had my moss for about 6 months now and ive noticed some white poping up on them....i do give them light but im not sure if they need it at all! Im being told 6-8 hours but I dont think thats correct....Any advice would be appreciated.

An overall wellness check is very helpful! :D
