Shrimp temperature: choose by species and setup

There is no ideal temperature for every aquarium shrimp. Choose a working range for the actual species and coordinate it with the animal supplier. A published tolerance extreme is not a target to maintain permanently.
Useful starting points
- Neocaridina davidi and many common dwarf shrimp: Garnelenhaus gives 18-24 °C in its beginner guidance. Treat this as orientation, not a proven optimum for every breeding line.
- Bee/Taiwan bee: consider a cool soft-water system separately from warm-water species. Ask about established breeding temperature and plan summer cooling too. The genus Caridina does not supply a temperature recipe.
- Caridina dennerli: Garnelenhaus describes approximately 27-30 °C in Lake Matano. This explains its different requirements, but a habitat observation is not a guaranteed safe aquarium boundary.
- Amano and fan shrimp: use the profile of the actual species; do not automatically adopt the bee or Sulawesi recipe.
Measure the water, not just the room
Check aquarium temperature with a reliable thermometer at its warmest and coolest times. Warmer water can hold less oxygen, so consider filtration, surface movement and waste load alongside temperature. Do not add heat solely to accelerate reproduction.
A heater is useful only if measured conditions would otherwise be unsuitable for the animals. During overheating, address the heat source and oxygen provision, then cool in a controlled way. A sudden cold water change is not a general cooling strategy.
Sources and scope
Measurement and preparation principles come from the cited sources. The investigation sequence is an editorial judgement. Fish farming, drinking-water or livestock figures are not established safe limits or treatments for dwarf shrimp. Product instructions apply to the named product.
