Question 1/4 gal with shrimp?

I have a small vase that only holds about 1/4gal. I have some potting soil topped with sand in it, some shells, and will be putting in some DHG. My question is, is it possible for a shrimp or two to live it it? Or is it just to small?

i could keep a couple of my culls at work in something like that, a pjreef (google) is about that size. the way I would do it would be to always have a clean gallon of water handy and never feed the tank midweek, only after its fully cycled and growing w plants Id put in a couple neos, 2 maybe, and feed only just before a full water change. mid week they'd pick on the plants. i have a half gallon that successfully keeps 8 neos and a fish, all correctly sized for something this small and incredibly well fed. a feeder guppy never had it so good.

1/4 is the smallest but yes I think it can be done, id be doing a couple full water changes once a week for a long time to stabilize it. large water changes are required, still and tiny tanks develop ammonia fast from just a simple feeding due to circulation issues, it tends to rot right where it lays unlike a movement tank where physical dispersion aids both breakdown and exposure to nitrifiers during the rot.

Bump: im about to buy a pj reef and convert it into freshwater check them out

I've done 2 shrimp in 1/2 liter (1 liter is ~1/4 gallon) so it's very possible. Use neo shrimp only, as I've found that they're the hardiest of all. I would remove the shells though, as they would be altering the water chemistry.

Mine was no-tech and indirect sunlight only. 95% water changes once a week, Osmocote+ pellets once every few months. I'd drop in a single flake of food 1-2 times a week. Healthy snail population in there as well. Make sure plants are growing by time shrimp are added, although I've also done a setup in the same tank where I added a shrimp 4 days after setup. It was fine.

I've also done a hands-off jar, even smaller, where all I would do is top off with fresh water. It was dirted, lasted for well over 2 years before I took it down. The snail poop essentially doubled the substrate volume at that point. I did have 1 shrimp in there, but very rarely fed it. It was more of a science experiment than anything else, and was quite interesting.

Not something I'd recommend as a general thing, but in the year or so I had it up and running, I was able to bring several cherry culls shrimplets to maturation and produce a second generation from the final adult male/female pair (the excess shrimplets were removed as they matured) in this pico 'tank'.

Small wineglass. Plain flourite as my substrate (deepest point was only 3/4"), various small plants. Weekly 20-50% wc.



Actual water volume was approximately 1 cup.
