Hi, I made my first jarrarium a few months ago from a nearby pond. Some soil at the base, then mostly water, and a twig or two. However it's looking a bit worse for wear - the inside is almost completely covered with algae. I do see creatures in there, but only the occasional flatworm and a lot of little water bugs.

Should I dump it back into the pond and start anew? I'm not sure if this is normal, or to be expected. And if it is, well, I can hardly see what's happening inside!

It has been getting direct sunlight, but I live at a fairly northern latitude so that shouldn't have had a bad heat effect on the jar.

pin-point sized skitters... what are they?

No point trying to post a picture or video as they're too small, but I have dozens upon dozens of tiny microbe things skittering about near the surface of my jarrium. Anyone know what they are?

Actually, while filming a leech I discovered they're easier to pick out on video than I imagined (may have to full screen the video to see them)

Daphnia

Posted: 02 Nov 2020 07:52 AM PST

I'm beginning with making a jarrarium, I have a small jar and I just put dirt and sand in it, and am now waiting for it to settle down. I'm gonna put in a bocopa plant in it, and probably some floaters, and I want to put in something like artemia or daphnia and maybe snails? But I think it's too small for snails. Long story short, I wondered if it's an okay combination of plants and stuff, and I wondered what I have to feed my daphnia or artemia if I put them in there.
