Flared carapace?

Iíve seen this shrimp in my tank for a while but havenít been able to catch a picture of her. This is the largest and presumably oldest shrimp in my tank and she acts totally normal. She eats ravenously, even standing up to the amanos for her spot at the food!

She has not always looked like this but for perhaps the last month sheís had what looks like an incomplete or flared carapace.

Is this a normal development in old shrimp? A problem with her previous molting? Genetic defect?

Just curious if anyone has seen this in their populations.

Honestly the flaring looks so dramatic Iíve been expecting to lose her for a while; but sheís been like this for quite some time without apparent issue.

That looks tough. It seems maybe an injury right after molting pulled it out like that???

If she didn't always look like that it would seem not genetic. Time might tell if any others have this as a condition rather than a one of a kind happening. Maybe the next time she molts it will be less pronounced or all corrected. Often it takes a few molts for things to return to normal, say in the loss of an appendage anyhow.

Not ever seen something like that before. Maybe someone else has first hand knowledge / experience of this.
Favorite tank right now - 12G Edge nano fish

New to FW fish? First tank in a long time or EVER??? Need some info on keeping fish?
