Hi,

I have spent some time on google but could not find same tiger like this one attached.
Parents of this shrimp are blue (possible mother is deep blue)

Thank You for any help.

Cheers,
Tomas

from the image and based from my experience, look like it is a tiger shrimp (common) or super tiger shrimp.

hope other who more advance can give more help and details

Looks like a pale mutant from Blue Tiger OE.

that can be a great news, the starter species for the "chocolate" variation from caridina shrimp

cchocolate is now just a general with neocaridina and many of peoples have it, but for caridina ? it can be a new trend

It is possible you may have a Tyrosinase positive (T+) albino. Many people are under the false assumption that albinos have to be colorless or white, but (to oversimplify it) there is a type of albinism that doesn't allow the black to express itself and changes it to brown. The most popular animals to see this in are snakes. *If* it exists in your tiger shrimp mutation, you have the brand new start of a fascinating line.

You may try looking at this thread. Perhaps water params or food have something to do with it if not T+

Personally I think it's worth breeding to the F2 generation to find out if it is inheritable.

Hi,

Thank You good people. To be clear. Shrimp visible on the picture has the same colour/color from the day 0 and ITS NOT stressed in any way. I`d say its Golden-Brown. She looks gorgeous in real! I have Blues, deep blue, light blue, blond, BT0, but this one is "catching eyes"

So, what would You suggest to cross bred this "freak"?

Thank You,
Tomas

Isolate it and to whom you are breeding it to.

If you know the parent, back breed your brown to him/her. If the phenotype doesn't present itself, breed it to his new offspring .

(back breed P1. If none, then back breed to new F1)

If you don't know the parent, then breed it to some of his bros/sis. If no brown pops up, then back breed to the new F1.

Alternatively, if you have NO idea where he came from, breed it, then back breed to the new F1.

Here's why- Albinism is a recessive, just like many mutations. If you luck out and the parent (or bros/sis) has the recessive gene, then your breeding project jump started.

If there are none in the F1s, the resulting offspring now at least carry the recessive. By back breeding to the new F1s, the color *should* show up in F2 and give you around 50% "mutated" brown color, 50% regular color carrying the recessive.

That's IF it is a simple recessive (as many mutations are.)

Hi,

Thank You very much for the advice! I have to print it, hard to remember all of these things

That day I had 3 females in the tank, one deep blue and 2 blue. I hope it will be a male.

All The Best,
Tomas

You know, when I was into the genetics of small mammals and reptiles, different breeders would place high prices on one or the other gender. The reasoning was simple, half would argue that the good female is worth more because they can have a large number of offspring, the other half would argue a good male is worth more because it can impregnate more females.

I always leaned more towards the males, too.
