Identifying Color Morphs

Recommended Posts

bluestarfish

Before I get to the main purpose of this thread, I've had a burning question for a while, how do you tell a Red (brown Heritage) apart from just a normal Red? (same for blues). Is that something you can only know by knowing the breeding line, or is there some tell in the shrimps coloration?

--

So I ordered a second batch to mix with the 10 I started with, they came sooner than I expected. I'm not quite done adjusting the TDS, but it's close enough. (man shaving the last 60ppm or so off is hard though, I think I'm going to have to do a fairly large change to get bellow 200). 

 

The bag(s) were very mixed, and many are lower grade than advertised. I'm not sure if I feel a little annoyed or not, I don't intend to breed them, but I know that they will eventually breed and dilute the brighter red ones I already have. On the other hand, there are some interesting shrimps in there. A couple of bluish ones, several that are a dark brownish red, and one that is fairly brown with a long white stripe down its back. If nothing else, if I ever do get into breeding them I guess I'll have genetic variety on my side...

 

Anyway, I'm trying to nab pictures of them to get help identifying their colors?

It can be hard to ID true colors if they haven't fully 'de-stressed' once in the tank and colors are still off from the stress of shipping and new environment....

Do you know what the deal with the stripy one is?

It's turned slightly redder now but still has a pale brown stripe down its back.

Most of them have turned a bit more red (though last I saw the bluish clear one it was still bluish clear).

 

Still curious if/how one can tell a (brown) red from a red red.

I can't tell for sure if the shrimp is brown or not... but the stripe down the back is normal for many shrimp. That's known as the "racing stripe", and is more often found in females in cherry shrimp, but can also be seen on high grade colored males, too.

I think it's red, it was kind of brown in color for several days, but it's gotten to be much redder today so probably just stress colors like you said? Some of them shift slightly in color in general (between dark red and brownish red)

It's nice to know that the stripe is just a normal variance in color and not something weird. There are a couple of others in there that also have stripes, but they aren't quite as prominent as on that first one with a stripe. I like the stripy look.

 

Also another picture just for fun.

They do appear to be about mid-grade!

 

Here are some grading charts.

Yeah, having pictures of live animals helps some.

I'm also still curious if there is any difference between a brown line red shrimp and a red line shrimp. Are they visually and genetically the same, or different?

Shrimp genetics sounds like it might be interesting to try to observe and explore whenever I have room for more than one tank.

 

I managed to get a better picture of the striped one since it's been coming out much more lately, and thought I'd share. Is the stripe something that comes and goes with molts, or a coloration that's always there? Do you know if it is genetic or epigenetic?

Ye, there is a difference between the normal red cherries, fires and PFRs vs bloody mary's. Although all are red to varying degrees, there is a difference in flesh color. Kind of like the different between a carbom rili (clear body, black patches on shell) vs a blue bodied carbon rili (clear blue body, black patches on shell).

 

As far as the stripe, it's genetic. I could be wrong here, but in the PFR line, they have been bred up to the point that the red stripe has encompassed the entire body, thus making them look 'painted'. Male coloration can vary a lot more than females. A BM line on the other hand is completely missing that stripe because they have a clear shell but red flesh.

 

Bloody Mary are a red offshoot refined from the Chocolate variety of Neocaridina, whereas Painted Fire Reds were progressively improved upon from the original wild-type. As a result, Painted Fire Red individuals have a red shell color while Bloody Mary have a red flesh color. 

In terms of offspring, it's not an automatic amazing result. You will, of course, have to spend quite a while culling. In another shrimp forum with mostly Australian members, I found a person who had mixed the two around a year ago. The biggest difference I could see was that the male he showed was fully red as well, rather than Sakura - Fire Red Grade.

Thanks for the explanation! That's interesting to know that it's a difference in flesh/shell color. I had gotten the impression from reading around that the shell isn't the colorful part since it's clear when they molt, but I guess there's a bit more to it than that.

      I came across this Japanese website that shows the biotope of Sulawesi shrimps.
      Thought you guys with Sulas would be interested. (Need Google translate to English).

      Thought I would share a few pics of the wonderful rifle shrimp that I received from Fishmosy.

      This is two of the males. You can see that distinctive stripe down their body. In the background basically at the bottom of the root section of the fern is a fresh moult from one of the rifles. The more I have to do with these shrimp the more I become fascinated with them. I think they are right up there as one of my favourite shrimp.

      This is one of the smaller male rifles.


      This one is more of a light bluish color and you can see how easily it would blend into its environment. Even though it's obscured there is an adult size rilli directly behind it. The look massive compared to the other shrimp in with them.

      I think the best picture I have ever taken of a shrimp. Couldn't do it again if I tried. I was actually able to put a tape measure up to measure the size of the rock and the rifle. The rock is approx 90mm and the Rifle is a bit over 5cm.There is a bigger one but it wouldn't co-operate to get a pic.  I also noticed the differences in color of the rifle shrimp. Considering their size it is amazing how at times they are very hard to see. They blend into their enviroment very well

      I don't know why there are such differences in color because I believe they all came from the same area. Perhaps Fishmosy or Bob can shed some light on the reason for this. They vary from a light blue to an aqua blue, green, brown and a light orange.

      Again, thanks for all the help. I ordered the Shrimp GH+KH minerals and they arrived today and did a 20l water change. I plan to do 20l on Saturday and 20l on Tuesday when I'm off, so that'll be over 100% water change. If my tank stats come back o.k, I might finally look into getting some shrimp next week.

      It is definitely more of a balancing act when trying to keep everything happy in a tank with Shrimps and plants, but don't be put off I think you will be fine. When putting the shrimps in the tank you should take hours of dripping to acclimate them and you may lose a few with the low Ph but I am sure it will work out in the end as cherry shrimps are fairly tough. If you use all RO water and GH/KH+ then the PH will always be lower even after the buffering of the soil stops, but this is the easiest route to go! If you go the mixed water 1:3 with GH+ the same applies but the PH will be slightly higher and will be cheaper (less GH+ and RO water needed), so overall this is the way I would go, and it isn't all that complicated once you get it up and running! As with JayC I doubt you really will need any ferts but if you must then use a lot less than the packaging recommends!  The best thing to do is just decide which route you prefer to go from the start as it gets so much more difficult to change it later? I don't have any issue with keeping shrimps/fish/plants happy and I don't use CO2 or any fertilizers so it is definitely possible and not that difficult if I can do it? I think that a lot of the plant fertilizers etc are really intended for plant aquascapes without any inhabitants but with fish and/or shrimps there will be natural fertilizer and the soil should have enough to start everything off? If you still aren't too sure I would just try running the tank without the CO2 or ferts (with the exception of as JayC recommends above) for a few weeks and just see how the plants get on, as you can start using either/both again at any point if they don't look like they are ok, but I expect it will work out fine. This will also give you time to mull it over at leisure? Simon

      You only need Flourish Potassium, as needed, in an aquarium. Potassium will be the limiting factor to growth in most aquariums. But with shrimp in the tank, I would dose it at 1/4 strength once every 2 weeks or more. Seachem Flourish for micro nutrients at half recommended dose every other 2 weeks in between the Potassium.   But !!  I don't believe you will need too much ferts in your tank. The type of plants and the amount of plants do not warrant much ferts at all. The waste from the fish and shrimps will be enough ferts, and if they are getting enough light a day, the plants will be fine without any additional ferts, except maybe a little potassium once every few weeks.

      O.k rethink. If I use that Salty Shrimp GH/KH stuff. Can you recommend any good fertilisers I could use for the plants? I'm not dosing anything at the moment.
    • DEL 707
      Not going to lie, this is giving me a headache. Just want a nice planted tank with fish and shrimp. 🤨 At the moment it looks like it have to either pick 1 or the other. Would this be a solution. Use Seachems Equilibrium and KH products to bring my GH and KH up to 4, then use that Shrimp King Mineral Fluid Double, to bring the GH up to 6. That would make sure that there are at least some minerals for the shrimp.
