I think I broke my terrarium

I made my terrarium in January and hadn’t watered it since it was looking great when their was condensation on the glass I would leave the cork off. Than it stopped condensing so I left the cork on for about a month my apartment is one wall of window so it get loads of light I put it behind my bed so it gets good light , I than noticed this fine white fur on the moss (third photo) I went to the place I made it and was advised to replace all the moss I purchased moss and removed the old moss and put in the new moss which is the next to photos, it was t the same type of moss but it’s what they recommended but I have noticed now the plants look sad and wilted I have misted the glass with cold boiled water but they are not looking any better. I think I have ruined it 😔

New terrarium my wife and I built, inspired by scandinavian woods

Had so much fun building this together with my wife. The red log looks absolutely amazing under the light and resembles stone formations near our house.

What do you think?

Showing off with beautifully thriving builds is much more fun than admitting failures. But it might be comforting for some to see that they are not alone in experiencing setbacks. https://hermetospheres.com/2026/05/16/unexplained-breakdowns/

Made a Highland cow habitat

Don't worry. He's a super micro-mini variety. 🐮

First isopod enclosure, need advice with pests

So I got my isopods from a bunch of leaf litter outside. However, some stray ants and TERMITES came alongside them😭it’s mostly isopods and I added springtails, will the few ants and termites die off or kill my isopod colony??? I hate termites so much

My newest creation ✨️

I've never made a terrarium before and got curious the other day. I took some tumbled stones, terrarium mesh, and soil, then threw in some baby's tears clippings from another plant and added a frog friend 🐸 what do we think?

Question as well: I have this terrarium next to my aerogarden (to the right in the photos, growing lettuces) — will the jar be a potential fire hazard? That's my fear. Any insights are appreciated!

I work in a kitchen/deli that has started doing more fish, and so we end up with lots of "pin bones" and such from processing them. I have a few terrarium tanks and am curious if taking home some pin bones for the tanks would be in any way beneficial for the critters in there (isopods, millipedes, etc). --- Or if it wouldn't really amount to anything and I should not go through the efforts! Lol
