My 2gal desk jar is 1 year old today! The microfauna got a pinch of shredded chicken as a birthday treat. Even the fingernail clams came out to enjoy the feast!

I'm really happy with this jar project. There is so much life in it, its almost like a full aquarium! No vertebrate animals, mostly just a big variety of microfaunt, 4+ species of snail, huge seed shrimp, daphnia, copipods, many strange worms, scuds sometimes… its an always shifting ecosystem.

I feed a variety of random things, bits of vegetables, cat food, random table scraps.

I've only changed the water once after I added some plants, no filter, no aeration, the plants take care of the oxygen. Almost no maintnence at all.
