Tiger shrimp confusion

Recommended Posts

Good morning all,


I am new to this (forum and shrimp keeping) and this is my first post! Thought I would start off by clarifying some of my confusion about tiger shrimp. I was initially under the impression the tiger shrimp was a Caridina Cantonesis shrimp (along with Bee and Crystal shrimp). If I am not mistaken that is the case with all tiger shrimp except tangerine tigers who are Caridina Serreta? Recently I have found some information online that said tiger shrimp are Caridina Mariae instead and are different than Caridina Cantonesis. 


On a separate note is there a simple explanation for the different between different tiger types, like Royal vs Fancy. 

I don’t even know where to start to figure this out, it’s hard finding this information online. Any help would be much appreciated!

Your initial impression that Tigers are Cantonesis might be because they were all classed under this name a long time ago. Recently, (I say recent, but it has actually been 5+ years now), evidence has shown that Tigers are a different sub species and therefore given a new scientific name of Caridina Mariae.

I'll try to give you an simple explanation.


Fancy tigers are hybrids. The term "fancy" is just given as a name to indicate that the Tiger has been breed with another species to produce a different pattern. It started with crossing Crystal Red Shrimps(CRS) and Orange Eye Blue Tiger(OEBT). And has now evolved to crossing with a Taiwan bee to produce a splotchy pattern. You can get a variety of colour like Red, or Black Fancy tigers being the most common. They are still essentially Tibees. But they have a distinct splotchy pattern.

You still get the distinct tiger stripes but they are a lot fancier in colouring.

Compare this to the original tiger shrimp Caridina Mariae below ...

Supertiger, Caridina mariae var supertiger orangetail ...


This one below is of an extremely high quality Fancy Tiger. Full colouration, no clear spots. The lines between red and white are clean and crisp, no blending of colours. The red and white colours are rich and intense. Legs are also coloured in red and not clear. This one is almost certainly a PRL cross Tiger.

Blue Tigers are a bit easier to explain.

Royal Blue is a colour variation name. It's just a name to distinguish it from the normal Blue tiger.

Blue Tigers are ... blue with the trademark tiger stripes.

Royal Blue as an extremely dark blue colouration, the stripes almost disappear in the intense dark blue.


Pictures speak a thousand words ...

"Normal" Blue tiger.

Anytime you hear of a term added before the name of the shrimp, its usually a colour variation.

Hope that helps.

      I've attached a small bit to the rock as the tank is currently cycling that had the crystal reds in it . I've always been torn between blue bolts and shadow pandas but blue bolts always wins. I never thought about taking some from my other tank and using them a tester but that is a good plan, saves me getting some blue bolts and then all of a sudden i have a big issue again. Hopefully not . That's why i am glad i have the bigger tank and also any of the lighter blue bolts can go into the bigger tank for culling. I've attached a few more favourite. My favourite shrimp which i think this is correct is an extreme bkk . I've also got a photo of one of my many red wines.  https://ibb.co/BVhDMMK https://ibb.co/42Q3ZYc https://ibb.co/gTD403T

      It may be worth holding off on the subwassertang as when you set up the new tank you can then use it in there? I think I could see a few red wine, if they aren't full size, could just have been the light though! There are 3 half size white shrimp with a red head between the large crs in the third photo of the sponge (about half way down), they are beautiful also .They may just be crs but the photo looks redder than those, but may again just be the light! My overall favourites are blue bolts also. I would use some of the crs though for about 3 months as a tester before getting blue bolts for the re-setup tank, you can then remove the crs. You have lots of the crs and you know they are healthy so it makes sense to use them (free) to 'test' that all is ok first, before getting the blue bolts! It will help mentally also, just think how devastated you would be if for some reason the blue bolts died because there is a problem (you won't know with them whether it was the shrimp or the setup), whereas you would still be upset with the crs dying but not as much - they were free and you have plenty of others in the other tank. If you want blue bolts only in the tank you may well get offspring of other colour/pattern depending on the genes of the parents, but then they can be moved to the other tank. ie Blue bolt mother and blue bolt father may create something not blue bolt, depending on the genes etc.

      Thank you, i enjoy a simple scape although i really need to try and take both sections of subwassertang out for a trim. They have just gone mad.  Things are doing great in this tank, i love my red wines as well bit couldn't find any at the time of taking a photo.  There is but i'm not sure they would breed true, i suppose it could be a project for me to breed them true but wouldn't know where to start. My other project i was thinking is just blue bolts in that tank , i love the colour.  I also suffer from slow breeding in winter although i've never had so much success with my taiwans/mischling that i hope it continues.

      That is a fabulous tank, is it built into a wall or partition. Love the simplicity of the layout, you can see lots of shrimp - I tend to overcrowd mine with plants so don't get to see so many shrimp. Great to hear that this tank is doing well and you have quite a few shrimp in there! Especially like the panda and blue bolt in the photos. As you have so many crs in this tank you shouldn't need to buy any more for your reset tank so that will be great and you know the shrimp are good quality and healthy, and that will make a bit of room in this tank for the next generation at the same time? You may experience the slowing down or stopping breeding for winter, though not everyone has that? Thanks for the photos!
