It's body looks like that of the cherry shrimp but its white. I dont think they are all dying but I cant be sure. I have heard of shrimp called snowball shrimp but I may be wrong. Asking the shop wouldnt help either since they sold them to me as ghost shrimp but obviously they arent Hopefully this picture will help. I cleared them out and usually they would give me a cheaper price but they found it strange as to why I am picking certain ones out and that cocky boy was working so he scoffed at me and kept calling me a smart *** for picking certain ones out. How rude haha, but yeah anyways, any help is fully appreciated. I will try to get a better picture in the mean time lol
