So, I'm pretty sure I just caught a shrimp being canabalized after he just molted. Do you guys think this is a sign of anything? Not enough protein, not enough feeding in general, or just "shrimp being shrimp"?   While I didn't actually see it happen, everything was fine before I went for supper and when I came back, I see a fresh molt and a nearby shrimp being eaten by about 4 others.   I currently feed once every other day. The tank probably has around 20 shrimp in total
