I really wish I could remember the reason why but I remember hearing people having a lot of issues using these as fish tanks. Probably best to keep it for succulents/fake plants
i want to find who or what inspired the trend of micro walstad tanks and push them off a cliff cause honestly 3 seconds of research should make someone understand that this is ridiculous
You could try sea monkeys? Or there may be a triops species that can be in this small of a container. I think fairy shrimp are also a thing? Id look towards those subs for advice
Scuds, not shrimp would work. You can try gravel, water, Hornwort and scuds, in a place with sufficene sun light. If you add food to it, you need to do a water change the next day of roughly ten percent so add it sparingly.
There are smaller options like scuds or other things the comments have mentioned. I think people underestimate how beautiful tiny water gardens can be. You don’t need livestock to enjoy your enclosure.
I think you can put some small pest snails in it tho. If the population increases just crush and feed them to your other tank

Would make a bad ass jararrium. But too small for shrimp
I now realize you meant Walstad and am deeply disappointed your sister doesn’t want a post-apocalyptic shrimp tank.
Too small like you said. Could be a good water planter.
You could maybe put brine shrimp (think sea monkeys or aqua dragons) in there! But that’s about it.

Would be a good scrotum holder for yours or anyone else’s scrotum. These scrote tanks have really gotten popular recently
too small for shrimps or snails, just put aqua soil and a few plants like anubias nana and java moss
Maybe a couple small moss balls
Teeny tiny.
Copepods, scuds, ostracades. Might be fun to watch.
I saw a bigger one of these in Florida. Almost bought it.

If you can get her to accept scuds as shrimp you could make it work, but I wouldn’t put actual shrimp in there.
put some rocks in and call it a day, no living creature should be kept in that.

Have fun and good luck.
Could be a scud tank! Love those little guys
yea the way they word stuff is crazy “recharge” and “several years” to describe lifespan
A marimo moss ball could work
put some river water in derr n see what happen

FYSA – I think the current reddit trend is a cat paw for scale, not half a sleeve of Rittz crackers. Lol
Brine shrimp and scuds. Cool sea monkey ecosphere
Moss ball!
I mean I guess you could put rice shrimp inside which are kind of like daphnia, but ultimately it’s way too small for any shimp
people keep ‘opae’ula in really small environments. virtually 0 maintenance
It may be too small for normal neocaridina shrimp, but it’s not for opae ula shrimp 🙂
