You can keep your ghost shrimp alive by fulfilling their basic needs, including:
- Providing them with at least 5 gallons of space, though you can keep four ghost shrimp per gallon
- Keeping the water warm, at around 65°–80°F (18.3°–26.6°C)
- Monitoring the water quality (no ammonia or nitrite and >20ppm of nitrate)
- Changing 30% of the tank’s water once a week
- Providing the habitat with plenty of live plants and hiding spots
- Keeping the water flowing with a weak current
- Supplementing their diet with algae wafers or sinking pellets two to four times a week
Additionally, you should buy ghost shrimp from reputable local sources. Some pet stores tend to mistreat ghost shrimp, causing them to get sick and stressed, thus shortening their lifespan.
