This is going to be disappointing, but I have to break it to you, those stripe colorations are just a different shade of black. Perhaps not intense enough, therefore, making it look reddish/maroon.
The red tigers in your other thread look nothing like red tigers to me. They look like culls from regular tigers that simply didn't develop the black coloration of their stripes too well. If I may ask, who did you get those red tigers from in the other thread? Because I'm not buying it (the story, not the shrimp). I don't think they're red tigers, unless you can snap more/better shots of them. And if you say that the tiger above has better coloration than the red tigers you bought, then there's clearly something wrong. **Note** Sounds harsh, I know and I'm sorry! I don't mean any harm though
They're great shrimp nonetheless.
Now, for some tidbit of info about red tigers that I've learned:
Red tigers are no different to regular tigers. Yes, the color is different but they're the same shrimp. Red seems to be a recessive trait (or so I suspect), so think of them as like CRS and they do occur in the wild. People seemed to have picked up the belief that red tigers are different to regular tigers because of how they've been marketed. However, wholesalers who collect these shrimp simply separate the red colored ones and the black ones from each other to make a bigger profit. Sell reds for a higher cost and blacks for a lower one.
Red tigers do exist, it's just not what you have. Red tigers show true red, not a dirty black that sits at an in-between stage of coloration.
Here's an example of my red tigers (old thread, decent pictures though!)
