Hey guys sorry for the ugly cell phone pics but I was wondering what you guys know what is on this yellow shrimp. Its has a red line on it and and has some red spots on it. At first i was thinking it might be some kind of worm but i was trying to take it out but couldn't, maybe it has to do with the shell? Let me know you shrimp experts! a couple more of my yellows have this also but they seem to be doing fine.
