Carte Euryrhynchus amazoniensis

  • GH : 4 to 15

Description : This shrimp belongs to the Typhlocarididae family (Annandale & Kemp 1913), and the under class of the Euryrhynchidae. The Euryrhynchus genus is known only in south America and was created by Miers in 1877 for Euryrhynchus wrzesniowskii . Other species have been described very recently, Euryrhynchus tomasi S. De Grave 2007. The second pair of periopods is transformed into relatively massive claws on the male and female. The background colouration is variable depending on individuals. However we find a colouration that goes from light grey to brown red with transparent zones. The abdomen is marked by stripes and blue or red specks that are characteristic to this specie.

Euryrhynchus amazoniensis Feeding habits : Omnivorous with a preference for meaty foods. Will take good quality flakes (with a high level of appetence) for fish. Although, feeding mustn’t be limited to only flakes. It must be as varied as possible with for instance fresh or frozen food made with small size prey (Mosquito larva, artemia, krill, and so forth…).

Sexual dismorphism : The males have larger claws than the females.

Reproduction : According to reports about reproduction on this specie, there is no larval stage. We then talk about a direct reproduction system where juveniles grow in fresh water conditions with a low pH. The female carries few eggs : 8 to 22.

Specificity : This shrimp is rare in the trade as rarely imported. The captures in the wild are difficult due to it’s small size and shy nature. They hide in branches and under leaves that are on the river beds. Cohabitation with fish is possible but must be limited to calm species.Euryrhynchus amazoniensis However, considering the rarity of this shrimp, it is preferable to encourage its breeding in specific tanks. The tank habitat will need to provide a leaf litter and bits of branches or roots. We can use tot that effect oaks leaves that have been dried first or bits of Euryrhynchus amazoniensis Terminalia catappa for a more natural effect, but also because of the various beneficial effects these leaves provide, like acidyfing the water specification, anti fungus or anti bacterial. Bits or mangrove roots or “Savannah” type roots will provide numerous hideouts. It is important to note that the more available hiding places, the more the shrimps feel secure, the more they come out of hiding and hop from plant to plant.
