Overview
Amano Shrimp are larger than Cherry Shrimp and are legendary algae eaters — Takashi Amano popularized them for planted tanks. They are transparent with a row of dots along their sides. Unlike Cherry Shrimp, Amano Shrimp larvae need brackish water to survive, so they rarely breed in home freshwater tanks. They are peaceful scavengers that get along with most community fish.

Expert Care Tips for Amano Shrimp
- Nano tank suitable: Amano Shrimp can thrive in smaller tanks (10+ gal), but skip the bowl — even small fish need filtration and a heater.
- Warm-water species: Amano Shrimp prefers 68–82°F. Use a reliable submersible heater with a thermostat — avoid temperature swings above 2°F per day.
- Narrow pH tolerance: Amano Shrimp only tolerates pH 6.5–7.5. Test your tap water before buying — adjusting pH is harder than choosing the right fish for your water.
- Peaceful community fish: Amano Shrimp works well in community tanks. Still, avoid housing with fish large enough to eat them — a 2.0" fish is vulnerable to anything with a mouth bigger than 2×.
- Acclimation: Always drip-acclimate Amano Shrimp over 30–45 minutes. Match temperature and pH gradually to prevent osmotic shock.
