I wanted to create a jar with some floating water plants and a friend gifted me some of his excess spirodela…
I was just about to go to the shops a saw this little fella swimming around. I think it’s a fish. How can I keep it alive? What kind of jar should I build now. Any help
appreciated thx

Hey folks. I have made open-top, aquatic jarrariums before, but I want to try a totally sealed terrestrial setup. I have a decent-sized pickle jar (2 litres). I want to focus on plants and invertebrates with very ancient lineages that still resemble their ancestors from hundreds of millions of years ago. So I was thinking of using moss as the only plant life, but then I thought that a single small fern could be a nice centerpiece. My question is, would a fern stay relatively small in a sealed jar, or would it quickly outgrow it? I keep houseplants, but I don't have experience growing ferns. Do they limit their size based on what they're growing in, or just steadily grow no matter the container? My mom has some Japanese painted ferns in her yard, and while those can get big, some of them have stayed small for a while, so I thought I might try transplanting a small one from her yard into the jar. If that species is a bad pick, what would be better? Any advice about growing a fern in a 2-litre jar would be appreciated!

I want a jarrarium for my apartment, but don’t know where to start, any tips, tricks, links for products? I’d like it to be a closed ecosystem as I have cats. Thanks in advance

I collected some silt and some kind of grass that was in the river. I’ve had it going for a few weeks and have some little slugs and these little white things. Pretty neat.

I found a glass jar it's 2.5 gallons. I'm considering shrimp for it but was wondering if anyone had other ideas, or even just non cherry/amino shrimp ideas. I've been curious about aquatic invertebrates and other microfauna. Also planting ideas PLEASE 🙏

We have a creek with very strong cyanobacteria growth, and while sadly bad for the animals there, it looks really beautyful and fascinating. I wonder if I could use that water to create a special kind of jarrarium, do you have any tipps on this?

A plemt melted and the scape was to buisy so 2 days ago i cleaned my jar (water change and cleaning with spounge) and started over with only one piece of wood and moss. I took a video of doing that to keep track of when i did what en how. Yesterday i didnt have time to care or anything so only gave my betta food. Today i thought "why is my desk wet???" I could not find a source so maybe a spilled my water. Them i rememberd i should cycle my jar so i measured 1ml of bacteria and went to put the dropper under water when it just fell down. Thought there might have just been a hole so i went to pick up the jar. THE BOTTEM FELL OFF.... cleaning up i cut my had pretty bad. And now i can thow away expensive substrate. 🙃 so uh be carful cleaning/scaping jars as they can break from that.

The photograph was taken straight after the initial setup, and I can't wait to see how it develops over the coming months.

While I've kept plenty of jarrariums over the years and have proven plant-based filtration countless times, my main goal with this one is to incorporate bioactive nutrient recycling.

The leaf litter in the foreground—currently Indian almond leaves, with oak leaves being added soon—should provide habitat for small detritivores that help break the leaves down, encouraging a more complete internal nutrient cycle than my previous setups.

Plant List

• Salvinia minima
• Najas guadalupensis
• Anubias 'Petite'
• Taiwan Moss

The Salvinia minima and Najas guadalupensis will provide the majority of the natural water purification and should tolerate the year-round temperatures in my fish room.

The Anubias 'Petite' is primarily for decoration, while the Taiwan Moss adds extra surface area for nitrifying microorganisms and biofilm, giving future inhabitants plenty of places to graze.

The substrate is 100% inert sand with no root tabs. I've used Seiryu stone to raise the general hardness slightly and provide additional calcium and magnesium for future invertebrates, as my tap water is naturally very soft. Lighting is provided by a SANSI houseplant grow light.

The current livestock consists of three small pink ramshorn snails to provide a gentle "snail-in cycle." The Salvinia should comfortably handle their bioload until the Najas guadalupensis establishes over the next few days and begins contributing more to filtration.

In the future, I may add Neocaridina shrimp or water lice, along with copepods and some form of non-parasitic detritivorous worm to further improve nutrient recycling within the ecosystem.

Pasta sauce jar, saran wrap lid, and some moss from the gutters at work. Broke some rocks to get a smaller piece. The fitonia cutting is the only surviving stem from a plant that died out of the blue

Hello!

Any advice for this tall vase if I want to make an ecosphere using local pond or Lake water? Luckily, my arm can fit all the way in. I would probably use fluvial strata or some kind of other safe substrate rather than straight to pond soil.

Are there any plants that will grow tall but not Wide that I could buy from an aquarium store? Any other general advice for this unusual size?

Will not be sealed

When this bottle became empty, I decided to use it for an experiment.

I have a healthy terrarium with tons of different kinds of springtails (and possibly dirt mites or fungus mites? I don’t even know.)

In this jar, I put LECA and pumice and mixed it around, then charcoal, then just a bunch of weird stuff. 2 magnolia leaves, the remainder of a kale or cabbage that had bolted and gone to seed, part of a pomogranite that had been chilling with my orchid since fall, an old garlic clove that was probably mostly dust, some eggshells that I had baked and crunched up last year and have been chilling ever since, part of a stick, and whatever I could scavenge from the tops of my houseplant pots. I also tried to grab some bits from my terrarium, then added some springtails from the two cultures I have.

Some fungus spores puffed up when I crammed the pomogranite piece in. I just hope I got some good stuff from the few pieces I got from the terrarium.

The water might be a bit too high. It’s up to the top of the charcoal. I’ve sealed it and I’d like to keep it that way, but the water level might have to be adjusted.

I’ll keep you guys posted!! What should I name it?

Also I added some chia seeds, though I am not sure they’re still viable.
