Science Tumblr or anyone who cares:
I made an eco-jar/biosphere one day from a local pond. Yes, I'm aware there is red algae, my last one did this and eventually settled with some adjustment and less sunlight and I cleaned it up and now I've just got some green algae going on and little sea-monkey shrimp, maybe detritus worms. I didn't have much for plants in that one though (although i have some tiny floating duckweed pads forming!), and clearly, these plants are not surviving. I do wonder what it says about the state of the ponds i collected from, or if its just a matter of my own errors. Not what I'm here to talk about!
I have a friend in this jar. I had found an earthworm in there the day i made it and thought he wouldnt enjoy living underwater forever, so I freed him in the yard. This particular friend didn't show themselves until a couple weeks later, and I've been watching them for over a week. I don't know what type of worm/nematode they are and I'm mainly fascinated but also slightly creeped out, haha. like I have an alien trapped in a jar.
Friend will come out every morning and do this little dance for a while. They swim around and hide under debris again. Then come out and dance some more. Sometimes they'll surface and stick their head out of the water! They suction onto the glass with their... butt, or sometimes hold onto the plant stalks (when they were fresh and sturdy) but I also saw them crawl INSIDE the stalk and def eat it. I believe they were eating the algae off the glass in the beginning, but it could have just been getting its bearings. I think they eat the tiny white swimmy things that I will simply call sea monkeys bc I don't have a microscope. So... omnivorous? opportunist?
My worm friend swims like a mermaid, undulating up and down with a flattened body, not side to side like an eel.
here they are right this second suctioned to the glass, sorry it's a 2 second gif:
please have a morning dance session:
I want to clean this up! level it out more (too much sand/rocks) and maaaybe put a small snail or two (to help with algae and bc fish would be very sad in these) in here eventually and get a couple plants that would be happy.
But is this worm be parasitic and came from like, idk, goose poop? will it eat snails if I put them in there? will it climb out one night and eat me like in alien horror movies? is it actually helpful and eating the bad bacteria and i got extra lucky? if anyone has any guesses as to what it is - lemme know. friendly advice on biosphere/eco-jars also welcome, it was my friends idea from a tik tok and I was like "okay, science experiment" and I got way more into it than she did bc she kinda gave up once hers got the algae bloom. I refuse!
okay so I think just got a video of heem eating? slowed down to 1/2 time. turn your volume down bc the fan was going so it's just droning in the background. this has all been happening while trying to write this!
bless myles for tolerating my shit, honestly.
