I would stay away from any fish. That being said, it’s pretty close to 5 gallons, and a heavily scaped, thick substrate 5 gallon tank might have less water than a lightly scaped 4 gallon tank.
I don’t think any fish could be comfortable and happy in such a small space. If anything, maybe a small snail if you know the tank can support the bio load and you can feed it properly
Don’t listen to the comments suggesting any fish. No fish, no matter how small, can comfortably live in a 4g(WITH SHRIMP). Stick to shrimp; they’re beauts!!
Not sure why I’m being down voted lol. 4 gallons isn’t suitable for anything but possibly a Betta but even then Betta and shrimp are not suitable tankmates. yeesh.
You could theoretically accommodate some of the species mentioned by the comments already but my two cents is just upgrade this tank size slightly or get another 5-10g solely for nano fish will make it a lot easier
7.5 gallon planted tank. Plenty of hiding room. 5 shrimp and 1 male betta. One very quick smart shrimp left—survived almost a year now. Learned my lesson.
You guys are all super overbearing. I have five super healthy sparkling gouramis and a few amanos in a planted 5g walstad on my desk. Granted 5g is more than 4g, but fine go with three or four instead of five.
I have other tanks with both platys and endlers, I would put a few small youngsters from those tanks in the 4, and as they got too big, I would swap them out for smaller ones. The benefits of having a few tanks.
Yes, there are fish species that can coexist with planted shrimp in an aquarium, such as corydoras and otocinclus catfish, Endlers livebearers, and guppies. However, it’s important to choose fish that are known to be shrimp-friendly and to consider the size of the tank and the number of fish added to ensure the health and wellbeing of all inhabitants.
While a shit ton of fish can live with shrimp, especially the neo/caridinia shrimp, 4G is quite small and do usually want a small group.
I would suggest half dozen celestial danio or ember tetras. They would be mid-upper water level swimmers so perfect to let the shrimp be at the bottom!
Here are a few fish species that may work well in a 4-gallon planted shrimp tank:
Endler’s Livebearers: colorful fish that are known to be peaceful and active. They can add a nice contrast to the shrimp and the plants in the tank. However, it’s important to note that these fish can breed quickly, so you may need to control their population if you don’t want too many fish in the tank.
Celestial Pearl Danios: another small and colorful fish species that can work well in a planted shrimp tank. They are peaceful and active, and they won’t bother the shrimp. These fish are also quite hardy and can tolerate a range of water conditions.
Betta Splendens: it’s important to choose a peaceful and non-aggressive Betta, as some can be territorial and may attack the shrimp or other fish in the tank. Additionally, it’s important to note that Betta fish have a relatively large bioload, so it’s important to monitor the water quality closely.
It’s important to note that any fish you add to a planted shrimp tank should be added slowly and carefully. You’ll want to monitor the water quality closely and make sure that the fish are not stressing out the shrimp or other inhabitants of the tank. Additionally, it’s important to make sure that the fish are not eating too much of the shrimp’s food or disrupting the natural balance of the tank.
I keep 4 male endlers in my 10 gallon shrimp tank. They do seem to predate on some of the shrimp fry but that tanks needs some regulation lol. If your okay loosing some babes then give endlers a shot.

Most fish that are small enough prefer to be in groups of 6 or so, which would be too many for that tank size
It’s probably not a great idea…
You can use it to grow fish fry until they are big enough to swim with the big boys
I’d keep it just shrimp, personally.

I’d recommend small snails or other small invertebrates, no fish would be suitable for that.
4g is too small for any fish. I’d stick to shrimp.
Your shrimp are gorgeous! I am absolutely shocked at the fish that people are suggesting.

No
a nerite snail!
No but you can add snapping turtle in with them
NO
No. Plain and simple.
Five gallons is typically considered the minimum for even the smallest and sturdiest fishes

Too small for fish even microrasbora can’t support
Nope

[Here’s](https://www.youtube.com/watch?v=_4k-tlYCEck&ab_channel=AquariumCo-Op) a video of Dean and Cory at Aquarium Co-op talking about stocking ideas for a *three*-gallon tank. These dudes are experts.

Even very small fish like dwarf rasboras will suffer in such a small tank. Imo 12-15 G is the minimum to keep fish at all.
Looks like you have lots of shrimp in there. I mean you could keep scarlet badis in a 4g but im not sure with the shrimp.
I’m literally raising about 50 CPD fry in a 5G. People gotta get a grip….
