When we get into keeping freshwater shrimps, one of the first questions we ask is, “Who can live peacefully with our tiny crustacean friends?” Choosing the right freshwater shrimp tank mates can be the difference between a happy, vibrant aquarium and one that’s constantly tense. We all want our shrimp to feel safe, and we also want to enjoy a healthy, diverse setup. Let’s explore how we can figure out the best companions, from mild-mannered fish to snails and everything in between.
Know your shrimp first
Before we add any new neighbors, we need a clear sense of our shrimp’s needs and behaviors. Different species of freshwater shrimp have slightly different temperaments, but most, like Cherry Shrimp or Ghost Shrimp, typically prefer calm waters and plenty of hiding spots. That means our shrimp are more comfortable if everyone else in the tank is calm, too.
- Active vs. shy behavior. Some shrimps are more outgoing, while others hide often. Outgoing shrimp might hold their own in a slightly more active community, whereas shy shrimp might do best with slow, peaceful tank mates.
- Habitat preference. Shrimp often occupy the bottom area of the tank. If we pair them with fish who also prefer the lower levels, we might increase the chance of scuffles, especially at feeding times.
- Sensitivity to water quality. Shrimps can be picky about water parameters, such as pH and temperature. If we haven’t reviewed shrimp-friendly conditions yet, we can visit our freshwater shrimp water parameters reference to ensure we’re on track. Any future tank mates must thrive in similar ranges.
As we think about which shrimp species we keep, let’s not forget resource links like types of freshwater shrimps or freshwater shrimp species that guide us through differences and special requirements. Our main takeaway is simple: if we understand our shrimps’ habits and environmental needs, we’ll craft a more harmonious community from the start.
Key factors for compatibility
Choosing companions for our shrimp is a balancing act. While personality clashes are a risk, there are other things we need to consider as well.
Temperament
We want to avoid any fish or invertebrates that are known to be fin nippers or bullies. Even small, feisty fish can see shrimp as a snack or unwelcome intruder. We’re looking for docile or mildly curious species that get on well in a community tank.
Size
If the fish are significantly larger than our shrimp, they might intimidate—or worse, eat—the shrimp. On the flip side, super tiny fish might be stressed if the shrimp population grows beyond expectations. Aim for tank mates that are in a moderate size range (usually under three inches), so no one ends up feeling threatened or overpowered.
Water parameters
We should confirm that all potential tank mates match our shrimp’s comfort zone. That includes pH, temperature, and water hardness. If we’ve set up a tank focusing on shrimp needs, we must ensure that the new fish or invertebrates flourish in similar conditions. For instance, a species that requires extremely soft water might not be a good match for certain shrimp that prefer neutral to slightly harder water.
Diet overlap
Food competition might sound minor, but it becomes a real obstacle if we bring in a species that hogs the lunch buffet. Although shrimp primarily eat biofilm, algae, or specialized shrimp pellets, many fish will also peck at those same foods. We might consider feeding practices that ensure everyone gets enough. It’s wise to check out specialized freshwater shrimp food if we suspect our shrimp’s diet is overshadowed by more ravenous fish.
Tank size and decoration
Tighter tanks can create friction between species, so if we have a smaller aquarium (under 10 gallons), we need to be extra careful with compatibility. Driftwood, rocks, live plants, and moss can help break lines of sight, giving shrimp places to hide and fish more room to feel separate. If we haven’t done so already, exploring a proper freshwater shrimp tank setup can help maximize space and create safe havens for shrimp.
Popular peaceful fish
Many of us dream of a lively aquarium swirling with colorful fish and bright shrimp. That’s certainly possible if we pick fish that have proven themselves to be good neighbors. Below are a few species known for being shrimp-friendly—most of the time, at least, if their environment is comfortable:
Neon Tetras
Neon Tetras are eye-catching due to their bright blue and red striping, and they’re famously peaceful. They grow to about 1.5 inches (4 cm) and typically spend their time in the middle of the tank. A group of at least six fosters a calm, schooling vibe, which usually leaves shrimp unbothered at the bottom.Ember Tetras
These petite orange tetras usually max out at about one inch (2.5 cm). Like Neons, they do best in schools of six or more. Their gentle temperament makes them an excellent choice if we want to maintain a shrimp-focused community.Harlequin Rasboras
Harlequin Rasboras are small, peaceful, and prefer to roam the midwater area. They’re often recommended for new aquarium keepers, thanks to their hardy nature. They typically grow between 1.5 and 2 inches (4 to 5 cm). With plenty of plants for coverage, these fish rarely bother shrimp.Corydoras Catfish
Corydoras are bottom-dwelling fish, so the risk of them clashing with shrimp is a bit higher if the tank is cramped. However, Corys are known to be gentle. If we provide enough room and an established freshwater shrimp substrate with hiding spots, Cory Cats tend to cohabit peacefully with shrimp. Just remember, bigger species of Cory might accidentally bump the shrimp while scavenging for food.
To make these examples easier to compare, here’s a quick reference table:
| Fish | Size Range | Temperament | Additional Notes |
|---|---|---|---|
| Neon Tetra | ~1.5 in (4 cm) | Peaceful | Keep a group of 6+ for schooling behavior |
| Ember Tetra | ~1 in (2.5 cm) | Peaceful | Also best in groups, bright orange color |
| Harlequin Rasbora | ~1.5–2 in (4–5 cm) | Peaceful | Hardy, good for beginners |
| Corydoras Catfish | ~2–3 in (5–7.5 cm) | Peaceful | Bottom-dwelling, needs extra floor space |
None of these species are guaranteed 100% shrimp-safe, especially around tiny shrimp fry. Still, if we set up the aquarium properly and provide ample hiding spots, these fish are among the most reliable companions.
Non-fish tank mates
Sometimes we want a shrimp tank without too many fish. In that case, snails or other small invertebrates might work as excellent “cleanup crew” while coexisting nicely with shrimp. Let’s look at a couple of popular choices.
Snails
- Nerite Snails. Known for their algae-eating prowess, Nerite Snails come in attractive shell patterns. They rarely disturb shrimp. Plus, they won’t reproduce in freshwater the same way other snail species do, so we don’t risk a huge snail takeover.
- Mystery Snails. These can grow larger than Nerites and might be a bit clumsy, but they’re generally peaceful. They’ll comb the tank for leftover food, which helps reduce waste. Just watch out for the occasional snail that might snack on very small shrimp if it’s missing protein in its diet.
- Ramshorn Snails. Though often considered “pest snails,” Ramshorns can peacefully coexist with shrimp. However, they can reproduce quickly. If we don’t mind the snail explosion, it can be fun to observe their population dynamics alongside shrimp.
Dwarf Crayfish
Dwarf crayfish species, like Mexican Dwarf Crayfish, are sometimes considered for a shrimp tank. They look similar to miniature lobsters. While they can coexist with shrimp, it’s a bit riskier. If a dwarf crayfish is hungry or feels crowded, it might pick on the smaller shrimp. We only recommend this pairing if we’ve got a large, well-planted tank with plenty of escape routes.
If we’re unsure about adding new invertebrates, we can explore more shrimp-focused references that discuss breeding or caretaker tips. For example, breeding freshwater shrimps explains how new little shrimp might appear in our tank, and we want to be sure no tank mate views them as lunch.
Handling aggression or tension
Every once in a while, we might end up with an unexpected bully or a fish that finds freshly molted shrimp too tempting. It’s frustrating, but it doesn’t have to mean the end of our shrimp community. Here are a few strategies:
- Rearrange the decor. Simply changing the layout of the tank can disrupt territorial patterns. Move driftwood, swap out plants, or add new caves so the aggressor fish loses its established “home turf.”
- Increase cover. If the shrimp have more places to hide, they can avoid conflict. Dense plants like Java Moss or Hornwort help with that, as do coconut huts or stacked stones.
- Adjust feeding routines. Sometimes aggression flares up at mealtime. Feeding fish on one side of the tank while we drop shrimp pellets or vegetable rounds on the other can divert attention and reduce competition.
- Remove the troublemaker. If a particular fish repeatedly hunts shrimp, we might have to relocate it. Alternatively, consider moving the shrimp into a dedicated tank if that’s an option.
We can keep an eye on our shrimp for any sign of stress: frequent hiding, color changes, or failing to come out during feeding. Shrimp that seem perpetually spooked might indicate we have a mismatch in our aquarium.
Tips for a thriving community
Setting up a shrimp-friendly community requires a little extra forethought, but the payoff is a vibrant tank where everyone gets along. Here are some quick reminders for ongoing success:
- Quarantine new arrivals. Any new fish or invertebrates should be observed in a separate tank for at least a week or two. Parasites or disease can quickly wipe out sensitive shrimp.
- Match activity levels. A calm, steady group of tank mates will let our shrimp forage along the substrate in peace. Hyperactive fish might cause accidental stress.
- Feed a variety of foods. Everyone in the tank benefits from a diverse diet. We can cycle between high-quality flakes, frozen foods, sinking tablets, and specialized freshwater shrimp food. This keeps the shrimp from going hungry and also boosts overall health.
- Check water regularly. Even small water quality fluctuations can mess with shrimp. Test pH, ammonia, nitrate, and nitrite levels often and do partial water changes when needed.
- Monitor shrimp reproduction. If our shrimp colony starts to grow, we’ll need to be sure the new additions are safe from predation. We could provide extra moss or “shrimp tubes” for the tiny ones to hide.

Wrapping up
When we talk about freshwater shrimp tank mates, it boils down to creating a stable, low-stress environment. The best approach is to match temperament, size, and water parameters so everyone feels at ease. Peaceful fish like tetras and rasboras make beautiful additions, while snails offer a creative alternative if we want an invertebrate-focused habitat. Ultimately, our quickest route to success is knowing our shrimp’s needs front to back, giving them plenty of cover, and choosing companions with similar lifestyles.
By taking time to plan, we’ll enjoy a gorgeous aquarium full of color and life that coexists in harmony.
