ok so I started the day off by looking at my tank everything looked good. came back a little while later everything was out and about I saw my peppermint shrimp sitting up by some zoas I thought it was a little odd ( they usually hang out under the rock except for when I feed ) it looked ok so I went about my day. came home a couple hours later first thing I do is check out the tank and the peppermint is in the same spot layed over dead I look closer and the belly is covered with eggs . I know they wont survive anyway. do they die when they have eggs cause everything else is doing great even my other peppermint shrimp is this normal? any advice would be nice
