shrimp turning white

update on my saddled shrimps: all of them have eggs already :) hoping to build my first shrimp colony. thanks to all yer advices.

btw i put a bamboo chopstick in my tank and the shrimps love it, they keep walking around on the stick. however i noticed a web like thing since my first encounter with the bug, do these nymphs spin webs? i see it everytime and it annoys me. thanks
