Hi all,
I just found a yellow shrimp (!)
I suspect it to be a transparent shrimp eating one the yellow-ish algea I can spot in a few places of my tank. It's not enterely clear to me why the translucent ones eating green algea arn't enterely green, with the same logic. I can only imagine the yellow pigment is smaller/gets out of the digestive track more easily and/or is less easily degraded so has more time to diffuse in the shrimp.
Now there is also a small chance it's a bad sign, so I just pray none of you will tell me it's a deadly disease
That's so cool! I've seen posts by Mustafa where he has shown some of his different colored shrimp, like orange, yellow, blue, pure white. His stock gets some colored "mutants." They are fine -- just a different hue.

Oh, thanks for the info ! I found the posts after reading you... That's really intriguing, because I can still see little red:pink dots of pigments on the shell; the yellow looks like it's within the shrimp.
Anyway, That's really great I didn't know it could be their normal phenotype. Always thought they were white to red and that's it. Thanks

Awesome! Is your yellow one still around?
Hi Mustafa,
Well, I'm not sure it is always the same, and it doesn't always have this bright yellow, but every few days I spot a one or two opae with this yellowish color.
I was able to take a picture of one that have almost no red spots, making the yellow more visible. I'm very curious about your project on yellow/orange shrimps, I've seen the recent post about it, it's exciting ! I think the yellow color is not due to a pigment on their shell or close to surface, but rather something inside.

Thanks for the picture! That shrimp has a bit of a red hue, so it's a normal colored shrimp that just temporarily ("temporary" can mean days, weeks or even months) lost its red coloration. The "mutated" yellow/orange shrimp don't have any red whatsoever.

A couple of the ones I got from Mustafa are pure white and always stay that way.
They may still turn red down the line. I have told this story before, but in my search for the mutant white shrimp with the blue-green eggs in my tanks I had isolated what looked like completely white shrimp but they all turned red after a few weeks or months...some really, really dark red.

Hi Mustafa,
All the shrimp (or at least all I could observe long enough and with enough zoom) I have displaying a yellow color have a few red spots at least. You can see them in them in the very first picture of this topic too.
That's why I was hesitant to place it at a phenotypic level same as "white" or "red". Yet, after several month, they are still around. 2-3 "yellow" shrimps. The phenotype I observe is probably different from the yellow ones you have, despite a close color (yours will probably have a way nicer/stronger yellow !). I thought about isolating mine to have a final word (observing them, separated from others, for months, to see the stability of the color), but I'm afraid it'll be bad for them as the only other tank I have is small and freshly cycled.
No, I haven't, after much reflexion. I'm only in the US for a few years, and I already get anxious about what I'll do with my tank when I go back to Europe. Additionally, I live in a very expensive city and don't have much room. For me to try to breed them, I would have to start a new tank of more than 1-2 gal (I tried to cycle a small one but it never reached stability as the bigger one did). So I dropped the idea.
I only see two of them, from time to time, now. But they are still here and seem to do well
Is your yellow one still around? And just for the record, I have never seen a blue one (in reference to a comment above).
