Mushroom! Signs of a good ecosystem in your terrarium.

I have springtails and isopods, the internet was a little conflicting. Will they be safe with the mushroom?

u/Eiroth 14h ago

yes

I teach sometimes and a science teacher gave me baby isopods and I carried them in a little jar all day and had my students address them as my children. I’m a little attached lol

That's the most adorable thing I've heard all day

Revising my confident yes to a more informed one: the most common species of Leucocoprinus found in plant pots has by some been reported as "potentially mildly toxic to humans". However, given lack of evidence and diffuse/low severity it's more likely that they are merely somewhat hard to digest and may cause some GI upset.

Here's someone who tried some for themselves and didn't experience any particular bad effects: https://www.reddit.com/r/mycology/s/X1w7pCzskf

Now, this may all be irrelevant as I don't know if isopods react completely differently, but I would be severely surprised given how common members of this genus are and the resilience of isopods!

TL;DR: I would personally not worry at all, but I sadly cannot point you to a scientific study specifically proving them to be safe for isopods.

There aren't studies like that becouse that would not be funded. There are environmental toxicology studies using isopods.
But isopods are extremely hardy. Everything once decomposes and then isopods could eat it.

Can't believe our society doesn't support toxicology for isopods

u/krrbystorm 13h ago

Should be fine, mine love to eat them as soon as they start to die. I’ve only had inkcap mushrooms though, so ymmv.

u/jeezyjames 12h ago

They’ll love it!

u/Fabulous-Accident689 13h ago

Just wanna let you know this is not a suitable long term enclosure for isopods at all.

u/SelkirkSweetie 13h ago

I’ve been taking off the top weekly for air flow. I’ll definitely do some more research though.

u/Fabulous-Accident689 12h ago

That truly will not help the isopods much, they need more space.

u/ClerkZealousideal779 13h ago

Not enough decay? Like wood and such?

u/Fabulous-Accident689 12h ago

Please do research before acquiring an animal even bugs, isopods are terrestrial crustaceans and need to be able to have a proper moisture gradient or they will suffocate/have trouble breathing. There needs to be a wet side and a dry side and enough space in the enclosure for it to actually be proper. Isopods cannot be kept in jars for this reason. They also need leaf litter to live in and other needs.

u/SelkirkSweetie 12h ago

Thank you so much, I’ll do some more reading.

u/Fabulous-Accident689 9h ago

Of course, I appreciate your receptiveness. I just care about the well-being of the animals.

u/SelkirkSweetie 9h ago

I don’t want to ever cause suffering to any living creature. The isopods and springtails were not originally part of the build, I had a group of hitchhikers on some plants I bought and they were suggested. I definitely want to properly care for them.

Leucocoprinus species, the tiny dots are what's known as sclerotia, little knots in the mycelium

u/SelkirkSweetie 14h ago

This is so cool. Thank you.

Looks like a classic case of dog vomit slime mold taking over your glass. It won't hurt your plants but it definitely means you have plenty of moisture in there.

u/SelkirkSweetie 6h ago

It grew in the hour I was home

u/Elevatormusicexpert 3h ago

Leucocoprinus birnbaumii it's warm and moist in there springtails can eat it up )

I love when I see the mushrooms. It means your terrarium is healthy. Also they grow so quickly lol 😂
