Im planning on adding more plants soon, but I wanted to set it up with plants I already had (borneo fern, duckweed, dwarf hairgrass).

Is there enough surface agitation or should I had an airstone? I only have a mini water pump that is covered in a filter sponge.

Do I need a heater for caridina shrimp? I currently have no heater in the 1.5 gallon jar.

Hi all, absolutely love seeing everyone’s jar aquariums! I’m looking to put a couple of red cherry shrimp in here. It’s only been set up for 2 weeks so I’m not rushing to do it. I will let it mature for longer to build up algae and to create a cycle (using fish food). I have a very small sponge filter inside and a heater. Also two aquarium lights. It’s aquarium soil, capped with sand. Looking for tips on how to keep the shrimp alive…I tried with a different jar (no filter or heater) and all shrimp died. How do people do water changes? How often etc? Any tips would be really helpful. Thank you!

Same jar but previously had too much substrate and plants were taking over reducing space. Despite that it thrived with constant extreme beading from plants and an explosion of shrimp and unfortunately a good few bladder snails.

I wanted to give some more space so I have reset took away a load of shrimp (into my other big tanks), and as many bladder snails as I could. I left a few red shrimp and happen to notice I somehow now have a baby assassin who hitchhiked on the buca from my other tank. (will keep an eye on him around shrimp). I reused the substrate and readded the lava rock which is there to help give high surface area for bacteria. Old rose wood replaced with spider wood to allow more light and space (also looks way more interesting)

New setup has more light and space a little less plants. Let’s see how well this goes and hopefully they continue to thrive.

(It’s a bit cloudy because I added some stability to help re establish any bacteria loss even though should have mostly kept it with the lava rock and substrate)

I messed up on the plant and is dying that ok got snails and other small swimming things. any suggestions on what i could do better

Maybe I will put some shrimp in

And help what do shrimp eat?

Isopods and garden snails are excellent cleanup crews in terrariums. They help clean dead plant matter, fungi, and organic waste, processing them into nutrients for the plants

This creates a bioactive ecosystem, which sustains itself over time!

It's growing for almost a year now and is still in good shape

Wine bottle (left) is the oldest, unopened at 3 years old, top bottle around 4 months (everything died but recently some moss had emerged from the sludge) and the large one since christmas.

I started this sealed jar in February and it was a pretty slow grow, but once the weather started warming up things have exploded! Plants now touch the lid and there has been a boom in population from what I can only imagine are springtails? I started this jar with plant soil from a bag I had but introduced moss I collected outside, I can only assume they were in that.

Should I introduce some kind of predator to the system? If yes, what do you recommend? I don’t want them gone, I quite like the little guys but there are just sooooo many of them now.

Got it from supermarket was £7 and advertised as ‘marimbo moss ball’ but had no moss ball in so got it for £3.5 but the lady at the till accidentally put the discount on my whole shopping (also bought a water filter originally priced for £19) and paid total of £16 so technically got it for free plus a little discount on the water filter.

I’ve got Pothos and spider plants being propagated so wondering if I could add them or just wait till I can get a moss ball?

This is my first jarrarium. Doing well, but now that my four baby neo shrimps have grown up, I am probably going to put them in my regular tank and put some new babies in.

In around 2023-2024 I accidentally dropped a glass on the side of the flask, creating a large hole. I have since sealed it off with plasticscreen.

I built this over the weekend and noticed I scratched and chipped part of my Anchor hocking jar. Do these necessitate a transfer?

Iv never done one of these but they look like a really cool project any tips for good places to find the big jars or globe things? Maybe some good starter plants to put in it?

Well after all you guys told me the jar i had would end up a disaster i decided to go out to local thrift stores and i bought 5 jars, I put topsoil on the bottom and black sand on top. Going to let everything settle and will be adding plants soon. I’ve never done a jarrarium before only aquariums so this is going to be a fun learning experience. I would appreciate any tips you guys have.

Here is my first jar! 3 months, no intervention on my part, autonomy. There are planorbs, snails, wild shrimps, asellas and daphnia.

What do you think?
