Setting up a tank with amano shrimp? Picking the right tank mates is key to keeping things peaceful and healthy. Amano shrimp (Caridina multidentata) are awesome for eating algae and cleaning up. But to make sure they thrive, you need to choose tank mates that won’t bully or eat them. Let’s take a look at some good options and what to consider when picking amano shrimp tank mates. With the right choices, you can have a tank that’s both beautiful and functional.

About Amano Shrimps

Amano shrimp, also known as Caridina multidentata, are pretty popular in freshwater aquariums. Here’s the lowdown on these little guys:

Appearance: Amano shrimp can get up to 5 centimeters (2 inches) long. They have a see-through body with greenish-brown coloring and dark spots or bands on their sides and back. They’re long and slender with thin antennae.

Natural Habitat: These shrimp come from Japan and Korea, hanging out in rivers and streams with moderate to fast water flow and lots of plants.

Behavior and Lifespan: Amano shrimp are peaceful and spend their time eating algae and scavenging. They live longer than most aquarium shrimp, usually around 2 to 3 years if cared for properly.

Water Parameters: They like neutral to slightly alkaline water, with a pH between 6.5 and 7.5, and temperatures from 22°C to 26°C (72°F to 78°F). Keeping the water clean is super important, so regular water changes are a must.

Feeding: They mainly eat algae and detritus. In the wild, they munch on biofilm, algae, and decaying plants. In your tank, they’ll eat algae but might need some extra food like sinking pellets, algae wafers, or blanched veggies like zucchini or spinach if the algae isn’t enough.

Compatibility: Amano shrimp are pretty chill and can live with non-aggressive community fish and invertebrates. But watch out for bigger fish that might see them as a snack.

Things To Consider

When picking amano shrimp tank mates, keep these points in mind:

Compatibility: Go for peaceful fish that won’t bother or stress the shrimp.

Size: Avoid big fish that might see the shrimp as food. Even if a fish is generally peaceful, size differences can be risky.

Water Parameters: Make sure the fish and shrimp have similar water needs.

Activity Level: Fast or very active fish might stress the shrimp or mess with their feeding.

Feeding Habits: Steer clear of fish that are aggressive eaters or that compete for the same food as the shrimp.

Hiding Places: Your tank should have lots of plants, rocks, and driftwood for the shrimp to hide and feel safe.

Observation: Keep an eye on how the shrimp and potential tank mates interact before committing. Look out for any signs of aggression or stress.

Good Amano Shrimp Tank Mates

Amano shrimp get along well with many community fish, but here are some of the best tank mates:

Small Peaceful Fish: Fish like small rasboras, tetras, and danios (e.g., Harlequin Rasboras, Neon Tetras, Zebra Danios) are good choices, as long as they aren’t big enough to eat the shrimp.

Corydoras Catfish: These peaceful bottom-dwellers are great because they help keep the tank clean without bothering the shrimp.

Otocinclus Catfish: Also known as “Otos” or “Dwarf Suckers,” these small algae eaters are perfect companions.

Dwarf Shrimp: Other dwarf shrimp species, like Cherry shrimp or Ghost shrimp, can live happily with amano shrimp, given enough hiding spots and food.

Snails: Snails like Nerite snails and Malaysian Trumpet snails can be great tank mates, helping with algae control without harming the shrimp.

Bad Amano Shrimp Tank Mates

Certain fish can be problematic for amano shrimp:

Aggressive or Fin-Nipping Fish: Avoid fish known for aggression or fin-nipping, like some barbs, cichlids, or bettas, as they might harm the shrimp.

Large or Predatory Fish: Big fish may see the shrimp as prey. Stay away from large cichlids, certain catfish species, or aggressive loaches.

Semi-Aggressive or Territorial Fish: Fish that can get territorial, especially during breeding, like some gouramis or cichlids, can be too intimidating for shrimp.

Fish with Different Water Needs: Don’t mix shrimp with fish that need very different water conditions, as this makes it hard to keep everyone happy.


  • Choose peaceful, small fish that won’t bully or eat the shrimp.
  • Avoid large or aggressive fish that might see shrimp as food.
  • Make sure the tank mates have similar water needs.
  • Provide plenty of hiding spots with plants, rocks, and driftwood.
  • Observe interactions closely to ensure a peaceful tank.

By keeping these points in mind, you can create a balanced, beautiful tank where amano shrimp and their tank mates thrive together.
