Live Hawaii Red Shrimp (Halocaridina rubra) ... also known as Ocean Rider Red Iron Horse Feed or Opae ulua.

Please adjust your salinity to 1.0114 for holding these shrimp!!

Unless you are planning on feeding all your red shrimp all at once to your seahorses please prepare a separate tank (or bucket) with a minimum of 5 gallons of new water for holding 400 shrimp for a short period and 10 gallons for longer periods. This tank needs to be cycled before adding your shrimp. You may use simple filtration, aeration and low light, habitat such as rocks or gravel  and tubes for hiding and getting away from the light (which they hate!).

Water quality parameters are:

Temperature 60F –80F, Ammonia 0, Nitrites 0, Nitrates  less then 10ppm PH 8.2 – 8.4, Specific gravity 1.0114 to 1.0122.


Be Sure to  Check the specific gravity to 1.0114!!

Prepare NEW water. Do NOT rely on the water the animals are shipped in for holding these shrimp. Check that the salinity of your holding tank is the same as the shipping water. If it is not adjust your holding tank so it is the same as the shipping water BEFORE acclimating. If you do not do this you will kill the shrimp. All other parameters must be within acceptable ranges.

Please acclimate slowly. The best way is to:

  1. Float the bag in your tank  for about 20 – 30 minutes to equalize temperatures.
  2. Then  partially open the bag and  add 1 cup of tank water.
  3. Wait 10 minutes.
  4. Remove  1 cup of water and add another cup of water from the tank.
  5. Wait 10 minute.
  6. Gently release the  animals into the tank, discarding the water left in the bag.
  7. Do not feed until  the day after arrival and acclimation.
