so, i was changing my water and i was watching to see how my cherry shrimp were adjusting to it. i threw an algae wafer in there, and of course, the smallest one got there first, and what happened. he got swarmed by my other cherries. i was really worried about him, and rite when i was about to go in and see if i could get him off, they slowly started leaving him. at first glance, he looked ok, and second glance, HE WAS FREAKING HEADLESS. my cherries are freaking cannibals!!!!!! is this normal behavior in cherry shrimp, or should i seriously be worried?
