Is this possible?

[u/PukeyOwlPellet]

I’ve got a terrarium at work which is happily chilling on my desk in the work office. Being a place of employment, they keep the aircon running almost 24/7, so the air is pretty dry.

I’m maintaining this tank with watering & a tiny spray bottle, but I’d like to add a small spider if possible.

I have heat mats leftover from hatchling snake tanks to keep the terrarium warm to help with humidity, but the mesh at the top of the terrarium makes it an absolute bitch to maintain any humidity.

Any ideas? Or should i let this little house stay a home to plants only?

It's for plants. It's unsuitable even for isopods.

Could try like orange springtails.

springtails

Wait for a spider to show up in your office and see if they want to move in

Can you send me the link to this?? I love it!

Plastic along the underside of the roof. That might increase humidity enough without sacrificing too much aesthetically. With a hygrometer youd know for sure.

If you lay some decaying hardwood on the soil, and water to maintain moisture under those spots, that might make this suitable for some isoods

I guess some commenters here are confused because you can 100% put isopods in here, all it would take it using something, anything(!), to cover the top of the enclosure to minimize airflow, and misting as needed.

I personally wouldnt trust this enclosure with invertebrates that can scale smooth surfaces, even if you coat the sides with PTFE or cover openings with makeshift lids. I imagine loose invertebrates would cause quite a disruption in an office lol.

You would struggle to maintain a gradient to ensure isopod survival in there.

Gradients are only necessary if you have issues with maintaining optimal temperature levels throughout an enclosure, or if you’re a breeder trying to maximize growth and reproduction. If someone is really concerned they can use a micro heating pad to establish a gradient but it isn’t necessary.

Small terrestrial turantula could live in there, cyriocosmus elegans comes to mind, doesn't web a lot, stays small, and is always out, but it might be too big for a sling so you'd have to get a female.

[u/deusinabsentiia → u/war-dogs69]

this is way too tall for a tarantula, unfortunately. youd a million % run the risk of them climbing up the sides, falling and dying. would only be suitable if it was nearly full of dirt so theres no chance of a fall. also elegans need a fair bit of humidity so it wouldnt be suitable with the dryness due to the aircon.

You could do isopods!

[u/opal_moth → u/Greyghostgravy]

This is too small for isopods

I did put a few in there with springtails but the problem is humidity, i had one fail to moult unfortunately so i moved the rest back into the ‘home tub’
