Crystal Red Shrimp and Sexing

by

Sexing of crystal red shrimps (CRS) can be done only at least three months old with confidence. At small, both sexes look like more like male. The differences are shown below:

Male Crystal Red Shrimp

* shorter abdomen

* longer atennules (the shorter pair of antennae)

* straighter carapace near rostrum

Female Crystal Red Shrimp

* thicker abdomen

* shorter atennules (the shorter pair of antennae)

* rounder carapace near rostrum

Sexing the Crystal Red Shrimp can be difficult at juvenile stage. Once females reach adulthood you can then tell the difference between sexes, or at least which are females. Females are easy to identify as they are larger and also have a curved underbelly. I do not believe that the difference in coloration is enough to truly sex this species. Instead look for size difference and more importantly the underbelly. The saddle of a female Crystal Red Shrimp may be virtually impossible to see due to the red coloration. You may however be able to see the saddle since it is a browning color. Photo of a pregnant Crystal Red Shrimp female below. Notice the curved under belly.

In the first pic a grade S tiger tooth

once grown, the females have an obvious saddle even when not berried.

Without better pics, they all look to be grade S and S+

This is one of the better resources for identifying features, but FYI it doesn't format correctly in Chrome or Firefox so you'll probably need to use internet explorer

Also, this is a better grading guide then the one that is usually used

I was lucky enough to have some SSS 'no entry' hinomura but uh.... 'something' happened. Expensive meal.

Get some mineral rock if you don't have any yet, seems to help a lot retaining shrimplets
