Yeah he looks a little…. special lol
As long as he’s eating and moving around, he’s probably fine.
Something might have gone wonky during his last molt. It will possibly go back to normal after his next molt
I recently had a shrimplet who looked like this, basically looked like he had no nose and had a creepy pale coloration on just his carapace . Although he ate well he swam very very weirdly, only in super super tight loop-de-loops. When i pulled him out for inspection i noticed the pale coloring was just from a piece of stuck molt, and if it wasn’t for the terrible swimming i wouldve just assumed he had a bad molt. (My other shrimp have never and still continue to have no issues molting, he has been the first and only shrimp with any issues) But since he was so bad at swimming combined with the bad molt i decided i wasnt gonna risk it and euthanized him. Disease? Bad genetics? Couldn’t tell you. This sub didn’t have any answers for me to go off of, and I’m still new to shrimping so there’s a great possibility i euthanized a healthy but ugly shrimp. If you can quarantine him for an extended period of time id recommend that
