Does Blue Velvet Shrimp Like Hard Water?
Blue Velvet Shrimp (Neocaridina davidi) thrive in stable and clean water conditions. They prefer slightly hard to moderately hard water, which helps with molting and shell development.
Water Parameters
- Temperature: 72–78°F (22–26°C)
- pH: 8–7.5
- GH (General Hardness): 6–8 dGH
- KH (Carbonate Hardness): 3–6 dKH
- TDS: 180–250 ppm
Soft water may lead to molting issues, so ensure your water has sufficient minerals. Remineralized RO water or tap water conditioned with shrimp-safe additives is often used.
Blue Velvet Shrimp Aquarium Needs
These shrimp are perfect for small tanks as long as you maintain consistent water parameters. Here’s what a proper blue velvet shrimp tank setup looks like:
- Filter: Sponge filters are best, gentle, and safe for baby shrimp.
- Plants: Java moss, Anubias, and Subwassertang are great for shelter and grazing.
- Substrate: Dark, inert substrates help show off their color and buffer water slightly.
- Decor: Driftwood and rocks provide surface area for biofilm, a key food source.
Ideal Tank Size For Blue Velvet Shrimp
Tank size depends on how many shrimp you want:
Quantity | Ideal Tank Size |
5–10 shrimp | 2.5–3 gallons |
10–20 shrimp | 5 gallons |
20–40 shrimp | 10 gallons |
40+ shrimp | 20 gallons and above |
For beginners, a 5-8 gallon nano aquarium is perfect—small enough to manage easily but large enough for stability.

Building A Nano Aquarium For Blue Velvet Shrimp
Here’s how to build an efficient, low-maintenance nano aquarium for blue velvet shrimp:
Equipment You Need
- 3 to 10-gallon glass tank
- Sponge filter with air pump
- Heater (see options below)
- LED light
- Shrimp-safe substrate
- Plants (Java moss, ferns)
- Test kits for pH, GH, KH, ammonia, nitrite, nitrate
Setup Steps
- Add Substrate: Rinse and add 1.5–2 inches of shrimp-safe substrate.
- Place Plants & Decor: Use rocks and driftwood to anchor the moss.
- Install Filter & Heater: Position the filter on one side; place the heater near the water flow.
- Fill with Dechlorinated Water: Use a plate to prevent substrate disturbance.
- Cycle the Tank: Shrimp tanks must be cycled for 3–4 weeks to establish beneficial bacteria.
- Introduce Shrimp Gradually: Use drip acclimation when transferring shrimp.
Heaters For Blue Velvet Shrimp Tank
One of the most critical yet overlooked components of a successful blue velvet shrimp tank is consistent water temperature. In nano aquariums, even a 1–2°F swing can be stressful for shrimp, potentially leading to failed molts or even death. This is why a high-quality, precisely controlled mini heater is essential, especially if your room temperature fluctuates or if you live in colder climates.
hygger offers a range of compact aquarium heaters designed specifically for small tanks and sensitive species like shrimp. Below are the top hygger mini heaters, each with unique advantages depending on your tank’s size, layout, and shrimp load.
hygger HG031 Super Mini Heater
