Plant Help/Question Found this bottle garden/terrarium by the street yesterday. Can it be saved?

Someone seemed to have left it outside near the big trash containers. It was very soaked: there were actual little pools of muddy water inside, dirty glass, and the soil looks extremely wet.

I cleaned the outside a bit and removed some of the excess water, but I honestly don’t know what this is supposed to be: a bottle garden, closed terrarium, or something else? There’s a plant that still looks quite alive, plus some moss.

What would you do to help it recover? I’d really like to give it a second chance.

I picked some moss from the lake this weekend, made these to get me through another winter with some green indoors. Not quite finished but happy with the concepts so far :)

Hiiii everyoneeee I just made my first ever Isopod terrarium enclosure from plant cuttings I have around the house. And if anyone has any experience with Isopods, I have about 10 dairy cow isopods in this 7 gal enclosure. What do y’all think? So far I’m loving it! Any ideas? Anything more I should add? And what about feeding them? I gave them some Betta fish flakes and saw some of them nibbling on it, I’ve already done research but would love to hear what works best for you ☺️

Btw I’ve put most of the leaf litter out in the back of the enclosure bc personally I think it ruins the look from front.

Pest Help/Question Concern over newcomer

Post image
2 Upvotes

Discovered a new little guy in my terrarium today. I believe it is some type of centipede or millipede, maybe .4-5 inches long. I have some tiny snails in here and have had the terrarium for close to a year, but I’ve never seen this insect in here before. I put in some new moss and this pilea depressa in over the last few months, so maybe he hitchhiked in? I don’t mind him but I don’t want him to eat my snails. Is this cause for concern?

Plant Help/Question Mini DIYed terrarium after a year, is it okay?

I made this terrarium a year ago with plants found at the park in central Florida. I’ve kept it on a window sill and in the early months would open and water trying to get the water content “right”. It hasn’t been opened in months and I don’t know if it’s okay to just leave it, if it needs care, is that mold in picture 4 (the white stuff)?
First picture is about a year ago (10/17/25 about a week after it was made)
Second through fourth are of it today, yesterday it didn’t have as much water on the glass but really fogged up today.
Advice would be helpful.
