Ghost shrimp are hard-water animals from the southeastern United States. They tolerate a wider chemistry range than almost any ornamental shrimp, which means the goal is not chasing an ideal number, it is preventing swings.

Target ranges

Temperature
65–80 °F, ideally 72–78 °F
pH
7.0–8.0
GH (general hardness)
6–15 dGH
KH (carbonate hardness)
4–10 dKH
TDS
150–400 ppm
Ammonia
0 ppm
Nitrite
0 ppm
Nitrate
Under 20 ppm

Why GH matters most

General hardness measures calcium and magnesium, the raw material for a shrimp's exoskeleton. Below about 6 dGH, molts start failing: the shrimp cannot build a strong enough new shell, gets stuck halfway out of the old one, and dies. If you are on RO or very soft well water, remineralize to a GH of 8 or higher before adding shrimp.

Why KH matters second

Carbonate hardness buffers pH. A tank with a KH near zero can swing two full pH points overnight as CO2 rises and falls, and pH swings stress invertebrates badly. Keeping KH between 4 and 10 makes pH essentially self-correcting.

Testing routine

  • Liquid test kits, not strips, strips drift badly with age
  • Ammonia and nitrite weekly for the first month, then monthly
  • GH and KH monthly, and after any water source change
  • Temperature daily by glance; a stuck heater is a same-day emergency

Water changes without shocking them

Change 10–20% weekly with dechlorinated water matched to tank temperature. Large, infrequent changes are worse than small, regular ones, a 50% change with cooler, harder tap water can trigger a mass molt, and mass molts in a stressed colony mean deaths.

From order to tank

  1. 1Order your pack. Orders placed before noon Eastern on Wednesday will most likely ship that same week.
  2. 2We ship Monday, Tuesday or Wednesday from New Smyrna Beach, Florida, so boxes do not sit over a weekend.
  3. 3Open the box on arrival, float the bag to match temperature, then drip acclimate.
  4. 4Net the shrimp into a cycled tank with cover. Never pour shipping water into the aquarium.
