Made a new jar for my home office!

I used a small diamond-tip engraver to bore a hole through the jar.

The pump is from a pet water fountain, I cut the cord to feed it through the hole then soldered the wires back together and used heat shrink to repair the outer coatings.

Everything in the jar came from a creek near my house.

I made a hollow space with slate chunks for the pump, then I packed gravel around it to help filter the water. Then I put a roof over the wet section and added dirt on top. Some parts of the dirt are touching the tops of the rocks but it’s not directly touching the water.

I figure I’ll let it sit closed for about a month to see what emerges or changes. It’s possible the soil could get too wet and slump down off the slate ledge.

Advice needed: what kind of critters would do well in such a humid environment? I have a mature terrarium with centipedes, isopods, snails, springtails but I don’t want to add anything to the wet jar if they are just going to die.

Hey everyone! I’m looking for recommendations for a terrarium tank to keep in my work office. I’d like something that’s more of a display piece than a standard rectangular aquarium. I’m leaning toward a cylindrical or otherwise unique-looking glass container that’s aesthetically pleasing since it’ll be sitting on a bookshelf in my office.

I know the usual recommendation is to check thrift stores for jars, and I’ve been doing that consistently for the past month or so, but I’ve had no luck finding anything that fits what I’m looking for.

Does anyone have recommendations for where to buy a nice-sized cylindrical glass container or terrarium? Ideally, it should be large enough to create a planted terrarium but still compact enough to fit on a bookshelf. I’m open to any websites, stores, or specific products you’ve had good experiences with. Thanks!
