Identifying Neocaridina Blue shrimp and genetics


Brentwillmers

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  

cheers

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.

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
