  There are very few species of shrimp that we will find surviving within imported live rock, those that do survive are either quickly eaten or are of the hardy types,which usually make them undesirable within a reef aquarium system. Those small and hard to see "bugs" that you may find running around after lights off are most likely not a shrimp species but members of any one of the "pod" families, for their identifications please refer to the zooplankton section.

For detailed photos of various Caridean species please see :

  The below Alpheus obesomanus and some of its relatives shown above are responsible for the small, long skinny claws that we from time to time see rapidly reaching out of small holes in live rock grabbing at the surface of the rock.  This particular specimen was also unfortunate enough to have been found by an Isopod parasite which remains attached to the shrimp. The large Isopod shown is the female, fully loaded with eggs and with this family of parasitic Isopods, the male, being much smaller than the female remains on the female at all times in order to serve his sole function in life, which is to fertilize the female's eggs.

   The Thalassinidean Shrimp - Found living within rock burrows, rarely seen as they are very secretive.
      Shown below is a gravid female:

   The Mysidae -  Order Mysidacea or more commonly known as the mysid shrimp or fairy shrimps.  The presence of a statocyst on the endopod of the uropod is a characteristic feature of this group.

   The Penaeid Shrimp


  Metapenaeopsis lamellata -  A common Penaeid species dredged from the deep and used as both a food source and as bait for fishing here in the Philippines.  This shrimp is becoming more popular within the aquarium hobby as a pet although I would caution against keeping them in a reef aquarium as they can be quite destructive towards sessile invertebrates, greatly reducing the diversity of life found on live rocks.

   An Isopod Parasite of Shrimp (click link for photo details):  Shown is a female Bopyrid Isopod which will have a dwarf male attached to her. While being a parasite, the Isopod does no real harm to the shrimp, any attempts to remove the parasite will kill the shrimp.

     Microprosthema validum  
         Related to Coral Banded Shrimp                                                                              
  Reef Safe and good fish food!  

   Saron Shrimp  -  Found throughout the tropical Indo-Pacific. Usually collected out of Hawai'i for the U.S., the Red Sea for European markets. Usually found in pairs in the wild. Will fight to the death if same sex individuals are placed together. Males with much longer first pair of walking/fighting legs.  Gets along fine with fishes, other crustaceans. Female shown. Will eat all types of food, is very reclusive and nocturnal.

OF INTEREST

  While highly unlikely to be found as a hitch hiker, I thought to include the following as it may be of interest to others.

   Microprosthema plumicorne - First described in 1880 with only four other known specimens in exsistence since then, all found near Australia, making this find a contribution to the knowledge of its range as it was found off the shores of Mactan Island, The Philippines.
