Description : Characteristic shape of the shrimps belonging to the Atyoida genus, very short rostrum without spikes (or just a few) and slightly curved towards the bottom. The antennular pods and also the scaphocerites segments are well developed and lined with fine hairs which make them easy to identify. The background colouration is marbled with blue and brown red. Some subjects present a transparent body colouration dotted of blue. The colouration probably varies according to the environment in which evolve Atyoida pilipes. This specie strongly appreciates strong currents in its habitat, juveniles climb up little water falls in rivers by crawling on wet substrates to be able to pursue their growth alongside the adults.
Behaviour : Excellent gregarious specie, it must absolutely live in groups of 4 individuals of the same specie no less, in a clear, clean and well oxygenated water. Cohabitation with small fish species isn’t problematic at all.
Life span : over a year.
Feeding habits : Filters for decaying particles.
Sexual dismorphism : The female is a bit larger than the male. However distinction between males and females is generally done by identifying anatomical differences on the male. The first set of pleopods as thinned endopods from their base to their extremity and the second pair of pleopods bear the male genital appendages that are of sub-cylindrical shape.
Reproduction : Reproduction is of the indirect type and necessitates a larval stage in salt water conditions. The complete development of the young to integrate benthic is unknown. To this day there are no reports of successful breeding in captivity.
Specificity : This shrimp is sensitive to acclimating, great care must be taken to offer a clean habitat that is well maintained. It favours spots facing the filter stream, to be able to collect with their fanned legs any particles floating in their direction. An additional pump to add current in the tank can be provided and will be greatly appreciated. This specie spends a fair amount of time searching directly on the floor to find it’s food.The Atyoida Randall, 1840 type is also represented by two other similar species that are much rarer or not commonly imported on the European market. They are the Atyoida bisulcata Randall, 1840 originating from Hawaii and Atyoida serrata (Bate, 1888) originating from Madagascar and Mauritius. The rostrum’s, the telson’s and the first set of periopods morphology, are the different traits that allow their identification.
