Some wood and/or rocks (in tanks under 5 gallons I stick to only wood, no large rocks)
– I have neocardenia in tanks as small as 1 gallon (they hitchhiker into the 1 gallon it wasn’t on purpose) and this formula works perfectly with breeding. However the lack of a heater slows the breeding.
I try to keep at least 5 shrimp together at a time.
more than 2 shrimp for sure, you can fit more than you expect in a gallon or two. you don’t need a heater if you don’t want them to breed. you should get java moss!
You probably don’t need a heater. That type of filter would also likely be too strong (and also generate some noticeable heat in a tank that small). Personally I’d just do a small airstone for water circulation and then add a few small buce or Anubias nana petite on a couple small pieces of rock to place near the airstone. A 1 gallon is really small, and I think if you can afford to go a bit larger (to even a 2.5-3 gallon) you’ll have a much more stable long term setup. But I do use a 1 gallon “tank” to acclimate my Opae Ula to full marine salinity for several weeks when I want to transfer a bunch of them to my marine inverts tank.
Shrimp are herd animals, like cows. They need plenty of friends, more females than males, I try to stay at 3 females for every male. That’s not for breeding purposes, it for my females safety. You could probably keep 10 shrimp in the 1 gallon. I know people who’ve had more than 100 in a 10 gallon, all happy and healthy. Smaller tank means more water changes, tho. It’s harder to keep the parameters right in a small tank like that.
air-driven sponge or undergravel filters work best with shrimp. Yes, water pump driven filters can be made baby shrimp-safe, but you’ll have to maintain them more often as they’ll clog up easier.
They are definitely more comfy with a lot of friends, but they wouldn’t care that much.
I don’t agree with the other comments, as long as you provide enough hiding spots and plants to get shadow from a lonely shrimp will still be happy and healthy. More is better but not mandatory.
If you really want a small population and name each one of them i’d still recommend 3-4 individuals with a lot of plants and cover.
If it’s important to you to see them easily at all time you’d want only a few hiding spots, and in that case 10 individuals is indeed the way to go.
Nevertheless depending on the species unless you specifically chose to get only males or only females, you’ll quickly get the shrimps filling the aquarium up to the population it can sustain.
More water, the water conditions will be more stable and lesser fluctuations. Too small tank, the water parameters easy to swing to extremes and since shrimps are highly sensitive, they can not adapt in time in a small tank.
Update: Hey thank you all so so much! I’ve learned a lot and added a lot to my shopping list for today! I’ll let you all know how it goes and try my best!
You won’t believe me now, but trust me that 1 gallon tank will end up being a headache. I’d get at least a 5 gallon, I have a planted 3.2 gallon with 6 shrimp and i wish it was abit bigger. I have three other tanks which are 10-20 gallon community tanks and the 3.2 has the most maintainace by far.
ten_dead_stouts 
2 shrimps only? that poor shrimps will be soooo lonely!!! please at least get 10 shrimps!
quick google search, you could keep up to 10 dwarf shrimps per gallon, but recommended would be 5/gal
also point to note, you should keep one colour per tank, unless you don’t care if they interbreed and produce wild type shrimps
Basic heater (optional)
Sponge filter
Live plants
Light for the plants
Substrate for the plants

Update: I got a 2.5 as it was cheaper and uta all set up now with 2 red shrimps and 3 ghost!
Just get a 10g to start, you’ll probably wanna upgrade fast lol
Shrimp love moss and don’t get a filter that could eat millimeter long shrimplets

Aquatop sells cheap 3-5 gallon kits but a 1 gallon can support more than 2 skimps
yea the basic idea works. you even do filterless if you have enough plants. do more than 2 shrimp tho. at least 10.
in terms of plants go for java moss or hornwort. theyre super hardy and easy to grow.
It’s going too be next too a grow light for hydroponic, does that work?
I have to ask: how did you come up with your “concept pic”? Is it from a website? Software program?

Just save up a bit more and get a 5 gallon and 15 shrimp.. 1 gallon will be hard to stabilize long term.. within 3 months the shrimps will die
Don’t listen to numbers, I have 13 shrimps in my 4L bowl and it seems empty hope the egnants hatch soon….
