About a week ago I got a fire shrimp and a cleaner shrimp. They have been doing great until today, I got home tonight to find out that, I cant find them. They both seemed fine when I left this morning but now im not sure, I was gone for about 10 hrs. Ive got a 100 gallon tank with a 5" naso tang, 2 yellow tangs, a tomato clown and a bi colored angel. I also bought a sandshifing star fish with the shrimp. "he seems to be fine" My parimeters are am.-0 Ni-0
-60. Salintity is 1.024 temp is 78-80. The cleaner shrimp had also been doing good and started cleaning the fish 15 min after arriving in the tank. Here is the kicker while searching the tank I saw what was once a part of the fire shrimps leg and I think the fan part of his tale. He was about an inch and a half to two inches long and the cleaner was about an inch. Im hopping you this could be them molting but I have my doubts. When shrimp molt, does the skin still hold its color? Do I have anything in my tank that would've killed them?
