Identifying Neocaridina Blue shrimp and genetics


Recommended Posts

Hi I wonder if someone could help with a bit of confusion I have regarding Blue verities of Neocaridina and the gene pool. 

This is what I have so far and not sure if it correct. 

1) Black/Chocolate Cherries will produce Blue Diamond. 


2) Blue Diamonds will produce higher grade Blue Cherries 


3) Rili will produce Blue Dreams

from there I'm not sure where Blue velvets fit in. 

What type of Rili will give you Blue  Dreams

Correct me if wrong, but it seems to me that Blue dreams and Blue diamonds are the same? Same as Blue Velvet are confused with Blue Jelly?

It's absolutely got me really confused. 

If you google search it gets even more confusing when you look at international naming of individual species/genes make up and try compare it to Australia naming. 

My question is what makes a Blue Dream, Blue Diamond, blue velvet, Blue Cherry. 

Does Balck/Choc cherries produce blue diamonds or do we use the term velvets. Then do we get higher grade Blue Cherries from this gene. 

Rili's will they produce Blue Dreams and if so is that what we calling it. 

Sorry about the mixed/messed up questions. It's so confusing that I can't think straight?

I know it's sort of been brought up before but not in detail on the Blue Neocaridina gene make up. 

It just seems a breeder will call their shrimp what they like and not by there gene make up. That's why I would like to know what does make up these shrimp and names associated with that gene pool.

As far as I know, yes, Blue diamonds (dreams) come from the chocolate, Blue Jelly (Velvet?) from the red rili, or should I say, rili comes from a cross beween the jelly and cherry?

I mean, which one came first? The rili or the jelly?, The hen or the egg? :thinking:

Here's my 2c (using Australian terms) sounds like you guys pretty much got it but I can add a little more detail.


Chocs -> blue diamonds (I have it on good authority that these are all but impossible to stabilise and will continue to throw an unacceptable % of browns and maybe blacks)


Carbon rili -> blue dreams -> blue topaz (with this line it is quite hard to breed the carbon out but not as difficult as the above example - I'm dealing with this dilemma myself)


Red rili -> superman/spiderman -> blue velvet (probably the most stable example of a blue neo to the best of my knowledge but also the least intense blue). I understand that the similar heritage is why my mixed up colony of red rilis and blues and spiderman (from which I picked out the red rilis for you) have never thrown anything fully resembling a wild type neo and at worst I've only seen very low grade rcs come out of it.


Also NB there are some blues getting around that come from a line which someone mixed up the blue from carbon and blue from red rilis and I know a breeder who came upon these and the progeny was most unsatisfactory.

Thanks William. 

It makes sense. I've never really been into the neo's until now and I'm liking it. But as you see I get mixed up with lines between them because a few sellers I've seen weren't quite sure themselves due to the differences in classifications from international labeling and what we call them here in Australia. 

Thanks again guys appreciate the input

Same here mate - I think it varies between Europe US and aus and Asian countries.

      In this video I'm going to show you a cool method of keeping two different neocaridina shrimp in one tank without mixing them. I show you how I separate small colony of yellow cherry shrimp from blue dream shrimp by using small breeding box.

      So I lost 3 shrimp today - two out of my 8 Blue Velvet Shrimp and my one Blue Dream. I don't know why or what the cause was although my guesses involve either overfeeding or possibly water shock from a small water change. 
      My parameters are as follows: 
      GH: 5-6
      KH: 5
      PH: 7.6
      Nitrite: 0 ppm
      Nitrate: 0.25 ppm 
      Water temp: 68-78 degrees F 
      My water is tinged green and I have 4 live plants (including a Java fern), a moss ball, an Indian Almond Leaf, and a Rock in the tank itself as well as one small snail. I got  a siphon pump today to be able to do easier water changes. How would one go about water changes in an area that is a bit colder than many other places? I started using cold water after making a mistake on using hot water which could have been a problem... but now that things are a bit more in place I want to try and get stuff settled. 
      If I got more shrimp: how long should I drip acclimate? 
      What would be the best way to use tap water for water changes when I only have one heater? Or would I want to use distilled water? 
      How often should I feed the shrimp? I keep reading all sorts of different tips and views. 
      Is it okay and normal for shrimp to hide under the rock? I have some (4) pretty small and pretty transparent shrimp that I haven't seen since I introduced them into my tank. I don't want to move my rock and find dead shrimp underneath...Maybe I should just give up? I don't want to but maybe I should figure out what is up with my tank first. Because I have no clue why this is happening. Is it my Nitrate and Nitrite levels?

      I have only been keeping Neocaridinas for about two months now, I have 10 blue dream neos in one tank, and 12 orange neos in a separate tank. The tank with the 10 blue dream neos has been slightly problematic though because it's a smaller tank and waste builds up a little faster.
      That being said, can anybody ID this swimmer in my shrimp tank? There is only 1 that I can see, it appears to have an exoskeleton almost like a shrimp, and it swims at the surface of the water by whipping its tail. I don't think it's a baby shrimp fry because I'm just now seeing my first female berried up and there haven't been any births before, but I suppose it is possible a fry snuck in with my order. Any help would be appreciated 😁

      I don't know if bacteria is the cause.  It seems to be an uncommonly diagnosed problem because most shrimp articles only talk about bacteria infection as "a few shrimp die every day / week"  What can I say, a standard dose of minocycline and erythromycin didn't work to stop it, so not sure if oxytetracycline will work.
    • jayc
      Ah yes. That was the injectable form of oxytetracycline. Each mL of the injectable form contains: 100 mg oxytetracycline HCl, 5.75% w/v magnesium chloride , 6 H2O, 17% v/v water for injection, 1.3% w/v sodium formaldehyde Sulfoxylate as a preservative and q.s. with propylene glycol. Basically, it has additional compositions in it. 1000mg might have been the dose recommended for the injectable oxytetracycline, but if you have the powder form then follow the dosing rates as recommended on your bottle. Hope that clears it up a bit.     As for doxycycline and it's use to treat short antenna ... I cannot comment on whether it will be more effective than oxytetracycline or not. But if you do use it, only try one at a time. Is bacteria even been proven to be the cause of "short antenna disease"?

      14 April 2015 -  Update based on experiences of one of our SKF members. Unfortunately for this shrimpkeeper it was too late to save these shrimps, but hopefully this experience will help someone else. 250+ shrimp were lost before the bacterial infection was halted.   A vet was consulted and he eventually ended up contacting a senior lecturer of aquatic animal health at University of Adelaide school of veterinary science. He stated that bacterial infections being internal or external are almost always gram negative in aquatics and recommended using oxytetracycline at a dose rate of 1000-2000mg per 40ltr of water.   Dosing method: Oxytetracycline is available in 2 forms. Powder and injectable. The injectable form was used as it is a stronger form. This meant that we could use less to obtain the required dosage.   Dosed straight into the water column at 1000mg per 40ltr of water.
    • jayc
      What?! Can you point me to where you saw that please?   If in doubt, Always follow the directions on the bottle.

      What is the recommended dosing for oxytetracycline?  The sticky thread has a mention of " 1000mg per 40ltr ", but I don't know if that refers to total amount of powder, or active ingredient percentage. I live in USA, where oxytetracycline is not as common, but I was able to obtain a bottle of powder.  On the bottle, it says [calculated out to] 75 mg / 10 gal, which is a wayyyy lower value.  Also, the manufacturer / distributor won't tell me the fraction of the power that is active ingredient vs filler. This is for a Taiwan Bee shrimp tank with pH 5.5 and Gh 5, in case that matters for the effectiveness of oxytet in these parameters. I also have doxycycline available if that is equivalent / better. It's to treat that "short antenna disease" in one of my tanks that seems to show up once every few months. I've already dosed with Maracyn 1 (erythromycin) and 2 (minocycline) and they didn't seem to work.
