New blues Shrimp morphs

bjar · Post by **bjar** » Mon Sep 18, 2006 2:24 am

Had a look at one of the biggest online invertebrate shops in germany .
They have two blue morhps of shrimp for sale .One is the same species as white pearl but is a nice clear transparant blue colour.The other one have a similar colour but is another species ,tupfel shrimp,
wich is a Caridina species related to the tiger/be shrimp group I think.

If they do look as nice live as they do on photo they are sure to be a big hit in the future.

I have been told that the blue ones you refered to do not breed true blue. You can have different color shrimp from them.

There is no population of true-breeding real-blue (i.e. blue like the blue crayfish) shrimp out there right now...trust me. It would be great to breed a blue morph some day, though.

Anyone figured out what they feed them to make them blue yet?

I hope there is a true blue shrimp someday, since blue is my favorite color.

Still no idea.

I'll take a wild guess and say that might be one of the stains used for staining cells for viewing under a microscope.

I'm not about to abuse a shrimp to find out though. . . .

I have had the wild form of the snowball shrimp. In my case they exhibited colors that were brown, blue and reddish. They were all in the same tank. I do not think it is something regarding food that is triggering the color. I might be wrong. In my case it was not.

What ever turns them blue stays with them their entire life and does not appear to harm them. This is why I think it is a food and not a stain.

Mine stayed the colors mentioned above. I isolated a few of each and fed them the same food. These were borned from my wild version of the snowball shrimp, F1 and F2 in my tanks.

Yucca, I think the dye you are thinking of is Methylene blue. We used it a lot in the lab at my university.

Mustafa, are the pictures posted in the shrimp varieties for amano shrimp of a blue amano shrimp? it actually does look blue/green

Methylene Blue,
Is this the same cemical that angle fish breeders use, as a anti-fungal, for there eggs ?

If so,

It is also used to turn steel blue. As in bluing a gun barrel.

It does dye you Skin for a very long time.

Looks like some new pictures. I have a few blue ones. Mustaffa assures me this is the same situation as the Neocaridina sp. "blue"

Here is a pic of one of mine in contrast to the normal color:

They keep that color their entire life once they get it.

Especially the mention of the color red makes me a little suspicious here. You might have received a batch of shrimp that might have crossbred with red cherries one way or another at some point in the past. I've seen this before...you receive non-red animals and some of offspring turn out to be red. Although the wild type snowballs can produce some interesting mutations (which they did in my tank), they all tend to be the same dark grayish coloration. Mine have never thrown any red/reddish offspring.

Not really. The blueish coloration is more apparent in the picture than in real life. They look like normal amanos.
