  • GH : 6 to 15
  • Temperature : 22 to 28°C / 71.6 to 82.4 °F

Size :

Description : Characteristic shape of the shrimps belonging to the Atyopsis genus, with a short rostrum and an orange brownish colouration background. The first and second set of periopods (walking legs) are equipped with fine hairs at their extremities, that the shrimp can spread like a fan to filter micro-particles floating in the water. The third set of periopods is very developed but isn’t armed with claws. A line goes all trough the body from the rostrum to the telson on the back of the crustacean. Specie that enjoys strong currents in their habitat.

Behaviour : Excellent gregarious specie, must absolutely live in groups of 4 individuals of the same specie no less. Considering the large size of this shrimp, a large habitat must be provided. Cohabitation with small fish isn’t problematic at all.

Life span :

Feeding habits : Filters for decaying matter.

Sexual characteristics : The females are generally larger than the males.

Reproduction : Reproduction is of the indirect type with a planctonic stage in salt water conditions. To this day there are no reports of successful breeding in captivity.

Specificity : This shrimp will favour spots that face strong currents, where it will gather micro-particles by using it’s fanned legs. This shrimp is often mistaken for Atyopsis moluccensis, however they are two distinct species. (See the next index ). The authors Andreas Karge and Werner Klotz refer to different distinctive traits such as the geographic localisation, the physical traits (rostrum, spikes, pleopods, and so forth) and the environmental traits (habitat, favourite spots).
