This morning, I didn't notice anything strange, My fishes were behaving normally, and my shrimps were still actively stuffing themselves. I only added some of the usual fishfood.

Then now, I noticed quite a few of my blue shrimp staying motionless for long periods of time. Some would occasionally rub their backs with their back legs. And my molly had also suddenly died with no apparent wounds, deformities or discolouration.
However, my cherry shrimps and other fishes were still behaving normally.

Are my blue shrimp trying to moult? Should I be helping them by adding iodine? I read somewhere that many shrimp keepers never needed to add any iodine, true?
Or could my molly's death be linked to their behavior?
Has anyone had a similarly sudden molly death before?

My tank is a planted 2ft, hangon filter, if that's any help. The blue shrimp and molly has been in the tank at least 2 week I think.
