Ghost shrimp coloration

We bought ghost shrimp from a couple of the big chain pet stores. They seem to thrive in our tank and they do an adequate job of cleaning the debris. A few of them have become fairly large. But I'm most curious about the coloration some of them are developing. It's not an overall color, they are still mostly clear. But they are showing orange/brown stripes down their sides and along the edges of their tails. I'll try to get some pictures this evening. I just wondered if anybody else had seen ghost shrimp do this.

I thought it might be caused by something they are eating. But that should cause their entire shell to show color. I also wondered if maybe it has something to do with their age or size. I haven't seen any mention anywhere of tiger-striped ghost shrimp.

It's not at all uncommon for ghost shrimp, especially older females, to show spots and streaks of color: orange, red and brown being the most common.

Interesting. Would that be considered an accurate way to sex shrimp?

It's odd how some shrimp thrive in our tank while others disappear. We've bought more than twenty ghost shrimp. But we only have seven in the tank. I had thought the coloration might mean the remaining shrimp were a different species and that explained why they survived.

Obsessed? Maybe

The easiest way would be to post some clear photos of your shrimp. Then other members can help explain what gender they are.

That said - Ghost Shrimp can be several different species and are often confused with Amano Shrimp by some big box stores.

Ghost shrimp can and will kill each other, so that may explain your problem, the ghost shrimp I had would display lines of orange on their tail once they reached about 1"

Ghost shrimp coloration

true ghost shrimps have several orange markings. one stripe on each antennae, two dots on the tail, and one stripe on each claw. They are non aggressive. if they try to kill each other or attack fish, you may have accidentally gotten a macrobrachum.

Don't know how to ID it, but +1 to macro possibility.

RAOK Club and BBRR Club! My thinking has been invert-ed!

I had just assumed ghost shrimp stayed clear. The coloration makes them even more interesting to watch.

I seriously hope we don't have any macros. Our favorite LFS had one they kept in a Rubbermaid tub. It was bigger than any crayfish I've ever seen. Looked like a small, clear lobster.
