My mom's favorite pretzels come in these jugs:

They hold about 1.5 gallons of water when full to the brim and I now have three of them sitting around. What should I do with them?

Toss em.

Hoard them!! For years till you have more than you know what to do with then toss them, only to find 2 weeks later you need one. lol I hold onto good containers like this too. I've used a few for DIY filters for certain projects/experiments and made one into a brine shrimp hatchery. I've seen other cut them down the middle (top to bottom) and use them to make caves or rocky mounds. I plan to use this kind of container when I make my DIY concrete rocks to make concave parts (caves).

Disapointed, thought this thread was about a medical condition.

Fill them all with your spare change. Then once filled cash out and buy something nice!

I meant as nano tanks! :iamwithst

Seriously, you guys are worse than my brother... :icon_roll

Moss gardens. Hospital tanks. They would be good for a few shrimp to selective breed. Etc, etc.

You could do a cool experiment and fill the jar up with coins as substrate, then some basic hardy plants. As time goes by you can add coins to the tank eventually filling it up?

I'm going to go with algae farm. Toss a decent size rock or two in each and grow food algae on them for your algae loving critters, if you have any.

The problem with that type of container as an aquarium is maintaining a reasonably stable temperature of the water. They over heat very quickly. And, they have very limited water surface area, so they tend to have little dissolved oxygen in the water, which isn't good for the fish or plants.

I might also suggest gonzo sized diy co2 containers. I still like the algae idea, I see these types of things in resale shops and make pick up a few for that purpose for feeding my oto. I have some spare air pumps I can use for aeration, if you have an air pump you could do the same. I'm not sure how well they would work for that purpose, @Hoppy made some good points so I will ask if Hoppy what about an algae farm and if those points would apply.

 

[Fishly]

Oh, don't worry. I wouldn't put a heater in something this small. I don't really use heaters anyway. I get cold before my fish do.

 

[thedood]

I am not 100% sure but I would imagine Hoppy has the heat from a light source in mind.

 

[Hoppy]

When I tried this I had it sitting in a window. Just the light from outdoors, not direct sun, was enough to raise the temperature too high. It was spring, and it got up above 80 degrees outdoors, and about the same indoors, so the water quickly heated up to that, then cooled down at night, and back up the next day - nothing survived!

Put house plant's and dirt in them.
Lousy idea for live critter's.IMHO
Poor surface area for O2 exchange,unstable temperature control(stressful for shrimp/fishes), easily fouled water with food's/waste.
Only half a step up from the tiny cup's /bowl's/vases that Betta's endure.

My apologies,Hoppy nailed it in post above .
I did not read enough before responding.

I've used these successfully to raise shrimp. It needs live plants and a spot away from direct light. If you keep the house at a stable temp that is. You can also use high light to grow green water and fairy shrimp. Last one I had was up for 2 years with cherry shrimp, but it does take meticulous water changes.
