Table of Facts


For freshwater tanks the Crystal Red Shrimp is a most popular species of dwarf shrimp. They are a very small species however are still packed with beauty.

Their actual scientific name is Caridina cantonensis var. ‘Crystal Red’. Rightly speaking they are a color variant of the Bee Shrimp (Caridina cantonensis), which is a member of the Atyidae family. 

In some Asian regions it is simply called Red Bee Shrimp. They were first selectively bred in Japan and this color variety was formed there, but nowadays they are bred around the globe. 

As they were created by humans, you will not find any Crystal Red Shrimp in the wild environment but the Bee Shrimp is native to Taiwan, and is useful to know when setting up your fish tank.

You have to be aware of grading while buying these beautiful shrimps. To indicate the quality of a shrimp this rating or grading method is used.

Grade goes up with opacity and whiteness and this is the general rule of thumb. The higher the grades the thicker white stripes on an opaque red, while Low grades are mostly a translucent red.

The price of a shrimp increases with the number of grades. You can pick some shrimp that fall into your budget. Therefore shrimp grading is useful . They will all look great irrespective of grades.

Their grades range from grade-C to grade-SSS, and as you raise the grade then the price could range from $5 to $15 per individual shrimp. 

 In home aquariums Crystal Red Shrimp have a very short lifespan. If they are healthy and fit then you can Expect them to survive for 18 to 24 months. So they require some excellent care to achieve the 2-year mark.

Typical Behavior

For any of their aquariums the Crystal Red Shrimp are harmless and won’t cause any issues. On the other hand there can be a problem though, as these shrimps are so small they’re quite vulnerable.

Particularly choosing the right tank mates is very important; we’ll discuss this later.

These shrimps spend the majority of their time walking across surfaces in search of food at the bottom of your aquarium.

By the way what is molting? Molting is a procedure where shrimps shed their old shell with a view to grow a stronger one. All shrimp regularly molt. They have to do this in some intervals because their shell does not grow with the rest of them.

After the process of molting, the shrimp will be vulnerable. The reason is it takes some time for their newly grown exoskeleton to harden and develop. To avoid damage they can probably hide during this period.

Don’t try to move them. Keep your eyes on them.

You will notice it’s shedded shell placed on the substrate. However you need not to panic. At first sight you might think it’s a dead shrimp, but when you look closer you can say it is an empty casing.

Remove the old shell because it will pollute your aquarium as it decays. Sometimes to have nutrients your shrimp will eat their old shell.

Their Appearance

These shrimps are one of the most wonderful species you must have for your aquarium. For a reason they are selectively bred.

They are stripy white and red but, as we said earlier, this may differ based on their grade.

There are a total of six grades: A, B, C, S, SS, and SSS.

In grade C the ‘Low quality’ shrimps are almost red, with a few thin white stripes on their body. The ‘high quality’ shrimps are almost entirely white with smaller red stripes on their body.

Grades are also influenced by the strength of your shrimp’s color. A powerful, opaque red is more desirable than a translucent red.

Mosura are the SSS-grade shrimps which are almost entirely white colored. They are the highest quality Crystal Red Shrimp. They just have bold red patches on their tails and heads.

It is simple to find out why this species is classified as dwarf shrimp; when fully grown they only reach 1.2 inches length. Particularly it makes those shrimps vulnerable to being eaten.

Still they possess all the features of a ‘classic’ shrimp. They are just shrunken down.

This includes some pleopods (swimming legs) under their abdomen, a telson at the end, long antennae, and pereiopods (walking legs) under their carapace.

Crystal Red Shrimp should be easy to mate. The female shrimps are 10 to 30% bigger and on the abdomen they have larger scales. Ovaries of a female are visible in their head and back when they get ready to lay eggs.

Tank Conditions and Habitat

Always try to recreate the conditions your aquatic pets would be used to in the wild while you’re trying to design a tank for an aquatic pet. It means that they’d want exact living conditions in captivity.

Crystal Red Shrimp only able to exist through the selective breeding of Bee Shrimp. Even they don’t have a natural habitat.

But, the habitat of the Bee Shrimp can be taken as a model because they are closely related to each other.

This would be Taiwan’s streams and freshwater rivers, which Bee Shrimp is native to. As the conditions are perfect, so many shrimp farms have been set up along these rivers in Taiwan.

Here the waters here are slightly acidic and warm. In these rivers and streams, the slight flow of water makes sure that there’s plenty of oxygen and pollutants are flushed away.

The riverbed would be covered in debris and densely planted to act as a shelter as and when required.

In your aquarium, if you can create similar conditions, then the Crystal Red Shrimp should live a happy and long life.
