Alpheus fenneri, Miya & Miyake, 1969
Crabs (Alpheidae), also known as pistol crabs, are a species-rich family of Caridea (shrimps). They are widespread in the tropics and subtropics, many species live in coral reefs. (but some also live in brackish water or even fresh water) Pistol shrimps are bottom-dwelling (benthic). They are also poor swimmers.
Some members of this family live in symbiosis with gobies and sea anemones, a few even with sea cucumbers. They are therefore also known as symbiotic shrimps, although the term crayfish has become established in the aquarium trade.
Alpheus fenneri lives with Cryptocentrus cinctus, Cryptocentrus fasciatus, Amblyeleotris guttata or Stonogobiops yasha, Amblyeleotris guttata, Amblyeleotris japonica, Amblyeleotris latifasciata, Amblyeleotris steinitzi, Cryptocentrus cinctus, Ctenogobiops feroculus and Stonogobiops xanthorhinicus, among others.
Bottom substrate
Sufficient coral rubble of 2 - 5 cm in size should be available so that the crab can also build a suitable cave. The height of the substrate must be at least 3 - 4 cm in some places (6 cm would be optimal) so that a correspondingly large cave can be built, depending on the association partner.
Alpheus is a genus of snapping shrimp of the family Alpheidae. This genus contains in excess of 250 species, making this the most species-rich genus of shrimp. Like other snapping shrimp, the claws of Alpheus are asymmetrical, with one of the claws enlarged for making a popping noise.
