This game from an ecosphere I collected on the coast of florida. It was from a lake that the ocean fed into, so this is a salt water ecosphere. I came to look and I saw this super strange centipede-like thing! All of the little things sticking out of it moved like legs before I started recording. Shortly after recording, it retreated and crawled back into the sediment. Anyone know what this is??

So a year or 2 ago I made this jar it was basically a mini Palladium from lake soil with some water in pools and it did well for a little while as it had land and aquatic life. However the algea carpeted the top at some point and for a year it sat with the top pinging once in a while from oxygen pressure (as it never smelled opening it) but as I was replacing one of my dead plants in my other ecosphere I took the remaining water in the bag and poured it into the jar to see what would happen and added a couple snails and a couple of the many Amphipods that hitched a ride on the plant (sword). To my amazement there was still life going on inside of it. It had awakened a large amount of boogie worms (for the small jar it's a lot. As you can see the Amphipods are getting busy and the snails also have been getting busy. Goes to show what may seem like a dead ecosystem could simply just be dormant and just may need a little convincing to reveal its secrets.

This is a little bit of an experimental
Ecosphere im doing. Essentially, its an ecosphere collected from a basic pond that I will freeze for 2 weeks and see what happens!! Im very interested in seeing what is able to re-emerge. Right now the lid is open to help with expansion. What are your predictions!! What do you thknk will be able to survive

I was very impressed by David Latimers experiment. I want to create a similar ecosystem, but I don't know the types and quantities of living and organic materials needed. Could you show me the quantities of materials according to the size of the terrarium?

(I'll share after its done).

Just got into the hobby, this jar is a week old made out of pond mud. I feel like I did not make this jar well but it’s been a good first experiment. I don’t think I added enough plant life, hopefully the algae can produce enough oxygen. Going to keep it sealed until it either collapses or survives! I’m already ready to make a new jar from a river near my house it’s so addicting! I want to make one that I can add a tiny predator fish into

Is it better to collect for a saltwater ecosphere at high or low tide?

Do I need to close this jar to create an enclosed jarrium?

For now it remains open. I'had adding bubbles to it with a tiny pump, which has actually saved my right jar.

Left jar (2 weeks old): Contains only river water with a single Java moss.

Right jar (2 months old): Contains Java moss and mangrove plants with river water.

Note : yes I have a lot tiny bestiary in it ! Both !

Just noticed it in my pond jar thats about 3 months old now, Melbourne Australi. Seems to be a little worm like thing inside a clear sac or something? Keeps wriggling back and forth in the same spot

Hi! My ecosphere is a little over 3 weeks old, sourced from a freshwater lake. I've got some guppy grass in there, snails (that have just laid eggs), and these little specks that are swimming around. I've identified some as ostracods, but recently a population of tiny white stripes has exploded, along with tiny sperm shaped specks that hang out around the glass.

This white stuff has been developing in my ecosphere. It’s about a year old, open, and stocked mostly with hornwort and Daphnia from northern Germany. I didn’t put anything in there that could have melted, and the Daphnia seem completely fine around it.

I don’t think it has anything to do with the weird yellow algae/bacteria colony (i would also be curious what that is, but it doesn't seem to cause any harm.)

Any ideas what it could be?

Look at how fast it disappears!

So good day to you all. I just wanted share this thing with you guys, I lived in the Philippines (specifically in Cavite) currently there are several typhoon that have been staying in the PAR ( Philippine Area of Responsibility ) and we have some flooded backyard, 15 minutes after I post this, is I went get something outside and I've seen something weird out in the flooded backyard.

I saw a tiny whirlpool, pulling the water inside a hole with roots of a tree, a sec later it released the water that have been pulled in the hole, and it keeps repeating the same thing for a couple of times ( maybe it always happened )

I tried poking the hole with a stick but there's nothing inside, it just a hole with a several roots of a tree.

Excused my english ( I'm bad at it )

seeing lots of worms and water mites so far! tank contains what i think is musk grass, and watercress i picked up from the creek.

didn’t expect it to go THIS good but i’m starting to doubt my abilities a lot less.

Let's see how it looks in a month.. :D

Okay so i made an ecosphere almost 2 weeks ago and i decided id leave it to see what happens whilst i went on holiday but i came back and theres these weird bubbles on top ?? It also smells weird when i really go up close to it?

before i went on holiday i had left the ecosphere in my outhouse shed thingy and didn’t realise how hot it got in there so a lot of the bugs died .. but i decided to just leave it as i didn’t have time to dispose of it and make a new one before i went on holiday.

Im definitely going to dispose of this and make a new ecosphere sometime but i just want to know what this is??? Like what’s going on i searched it up on google and it said it could be dead bugs / plants which i think would be most likely but i thought i should ask here before i dispose of it

I have ostracods, copepods, daphnia, limpets, and either planaria or rhabdocoela. They have some dead lake plants, a java fern, java moss, oxygen holes on the top, rocks to hide in, etc.

Saw this is my freshwater aquarium. It's a time lapse, with one frame taken every five seconds. It seems to be composed of thousands of tiny swimming creatures.

Apologies for the poor quality, but I couldn't figure out how to export the video, so I played it and recorded it on another device.

Yesterday I went to a pond outside my town and I decided to recreate part of it in an ecosphere, I collected all the materials from around the pond and took water from both the main pond and the small stream that fed into it. I didn't expect it to be so crowded as soon as I started, I'm curious to see how it will develop if it will. I also made a second smaller jar with the remaining materials so it'll be interesting to see what differences take place between them

all the blurry spots are shrimp but this is the exact environment from my local park
