Crystal Red Shrimp Grading Guide

Click for the QUICK Grading Guide

Click for the QUICK Features Guide

Overview

The grading of the Crystal Red Shrimp has sometimes created more

confusion than concrete answers. Not only are there many different grades

but there are also several different color patterns, features, terminologies

and other factors which can dictate one grade from the next. Being well

educated with the grading of the Crystal Red Shrimp is very important if

you decide to acquire, keep and breed this species.

There are numerous factors which can dictate the grade of a Crystal Red

Shrimp. One of the most important factors is the intensity of both the white

and red coloration on the specimen. If the white coloration is not full and

shows signs of transparency then this can downgrade a specimen. When

obtaining Crystal Red Shrimp from another breeder it can sometimes be

common for a specimen to lose its fully opaque white coloration when

newly arrived and also if it is an older specimen. It is recommended to

purchase non-adult Crystal Red Shrimp if you do not want to risk potential

color loss in adults after shipping. Adult Crystal Red Shrimp can be very

picky when being introduced to a new environment.

Color patterns are also a very important factor when grading a Crystal Red

Shrimp. Patterns like Hinomaru, Tiger Tooth, No-Entry Hinomaru, Mosura

and more can dictate one grade from the next. At the bottom of the page is

a guide to the common features/terminologies which are associated with

certain grades. It is highly recommended that you are well educated with

the grading terminologies of Crystal Red Shrimp if you decide to keep this

species.

Please note that there of course has not been an "official" Crystal Red

Shrimp Grading Guide. This version was created in order to help hobbyists

better understand the grades and their respective terminologies that are

associated. As more information develops on this ever changing Crystal Red

Shrimp species this page will be updated.

Many thanks to Henry Hua, Gabe Hernandez & Kangshiang for the photos!

SSS Grade Crystal Red Shrimp

The SSS Grade Crystal Red Shrimp has the most white coloration out of all

of the grades below it. It is sometimes refered to as a "Mosura" grade

Crystal Red Shrimp. It follows the typical rule in Crystal Red Shrimp

Grading that the more white coloration the higher the grade. However,there are many features which can make one SSS grade specimen

considered even higher grade than another SSS Grade. One SSS Grade can

be higher than another dependent upon features including the different red

patterns on the head, eye coloration, leg coloration and even antennae

coloration. As the grading gets higher there are more factors which can

make a single specimen more prized than another of the same grade.

Please read about the grading terminologies located on the bottom of the

page.

SS Grade Crystal Red Shrimp

The SS Grade Crystal Red Shrimp has more red coloration than the SSS

Grade. The additional red coloration is located on the mid portion of the

body, typically on the top. The SS Grade is usually given when there is a

"Hinomaru" which is a red circle on the back which in fact signifies the sun

in the Japanese flag. There are different varitiations of the Hinomaru

including a No-Entry Hinomaru which is a white line through the red circle,

and a Double Hinomaru feature which occurs when there is a second red

circle on the body typically right at the end of the back at the tail. In the

various photos below you can see the different types of SS Grade Crystal

Red Shrimp. Please read about the grading terminologies located on thebottom of the page.

SS Grade Hinomaru

S Grade Crystal Red Shrimp

The S Grade Crystal Red Shrimp has even more red coloration than the SS

and SSS Grades. The additional red coloration is located more along the

sides of the body versus the SS Grade which has red mostly on the top

portion. The S Grade Crystal Red Shrimp is a more popular grade due to

the lower price and also because it is considered to have a more even

white/red coloration. Some do not prefer the majority white coloration that

the SS and SSS grade provide, let alone the high price they can demand.

The S Grade can also be ranked as S+ given certain characteristics like

solid red and white coloration as well as special features including TigerTooth and V-Band. The grading of Crystal Red Shrimp from S+ grade and

below is very dependent on color solidity. Nice fully opaque white and red

coloration can make the difference between an A Grade and S Grade. It is

very important to inspect each specimen thoroughly. Please read about the

grading terminologies located on the bottom of the page.

The A Grade Crystal Red Shrimp is a more popular grade for beginners in

the Crystal Red Shrimp breeding arena. The A Grade has characteristics of

blotchy and transparent red coloration and poor solid white coloration as

well. A lack of any special features/patterns is typical of an A Grade

specimen. The distribution of the red and white coloration can differ where

some can have three white bands and some can have four white bands. The

A Grade is a great beginner grade and are very inexpensive compared to

higher grades. As stated before, it is important that you inspect each

specimen well because an A grade can be improperly labeled as an S grade

if not careful.

A Grade 3 White Bands

A Grade 4 White Bands

B Grade Crystal Red Shrimp

The B Grade Crystal Red Shrimp is typical of poor distribution of red and

white coloration with an almost complete lack of any fully white bands.

Some would say it is an ugly grade but I suppose it is in the eye of the

beholder. This is another great beginner shrimp and also a great shrimp for

breeders who are interested in practicing selective breeding. The irony is

that it can sometimes be hard to find low grade Crystal Red Shrimp like the

B Grade since not many people are fans of i ts pattern/coloration.

C Grade Crystal Red Shrimp

The C Grade Crystal Red Shrimp is typically where it all started. The very

first Crystal Red Shrimp looked closely like this. Over time the white

coloration was bred out and became more prevalent than the red

coloration. You can see how the red coloration is almost 100% with very

little white except for a coulple of strips. This is almost exactly what the red

colored variety that Hisayasu Suzuki first discovered in his batch of wild

Bee Shrimp looked like. Very little recognition is given to this grade given

the fact that it is the origin of the mainstream Crystal Red Shrimp. There

have been attempts to breed the red 100% with no white but lately it has

not been as popular to do so.

Grading Terminology & Features

8/12

Mosura "Flower": A Flower-like pattern on the side of the head of a SSS

Grade Mosura. Exactly where the "flower" term originated from is unknown

as it does not seem to resemble a flower too much. Found in SSS Grade

Crystal Red Shrimp.

Mosura "Crown": A half-circle Crown-like appearance located around the

top and sides of the head. Found in SSS Grade Crystal Red Shrimp.

Double Hinomaru: Instead of one circle there are two. A large circle in the

back (with no-entry sign) and another small circle towards the tail. Found

in SS Grade Crystal Red Shrimp.

9/12

No-Entry Hinomaru: Occurs when a white dash appears in the middle of

the red Hinomaru circle. The white dash gives the appearance of a No-Entry

sign commonly found in traffic signs. The white dash can go all the way

through the sides of the circle or can be contained inside as well. Found in

SS Grade Crystal Red Shrimp.

Hinomaru: Hinomaru is when there is a distinct Red Circle in the middle

section of the Crystal Red Shrimp top back portion. Hinomaru means "sun

disc" in Japanese and is symbolic of the red circle which symbolizes the

Sun in the Japanese Flag. There are also different variations of Hinomaru as

stated above, i.e. Double Hinomaru and No-Entry Hinomaru. Found in SS

Grade Crystal Red Shrimp.

10/12

Tiger Tooth: The Tiger Tooth marking is located on the lower half of the

middle red section of an S+ Grade specimen. There are two red downward

dashes. In between those two dashes is a white "Tiger Tooth". There must

be a white portion between the two red dashes in order for the Crystal Red

Shrimp to be considered to have a Tiger Tooth. If the area between the

dashes is clear then it is not considered Tiger Tooth. The lack of a second

red band would in fact create a V-Band instead. Found in S+ Grade Crystal

Red Shrimp.

V-Band: The middle red section is shaped as a pseudo "v" shape signifies

V-Band. Found in S+ Grade Crystal Red Shrimp.
