amano shrimp snacking on Crystal reds?

I have a super heavy 55 gallon planted tank with perhaps 200 crystal reds and 20-30 grown adult amano shrimp that are huge. Both my wife and I keep seeing them snacking occasionally on crystal reds...and I'm not talking about ones that are clearly dead for a while but perfectly colored ones. They are pretty ruthless about it too, "cutting" the shrimp into two pieces and eating the inside. I know this isn't common so I'm wondering if it's possible they are going for freshly molten ones? I have never seen them attacking juvenile or baby shrimp.

Has anyone else had a similar experience before? This started when the amanos reached full size, and yes, I'm 100% sure they are amano shrimp and not some other species. Is it possible I don't feed them enough? (daily flake food and every second day batter AE or shrimp pellets).

I have a ton of sakura cherries in with a bunch of amanos and "petco labeled amanos" and I've never seen them eat them not even the tiny ones. They do boss them around when i drop an algae wafer in once a week, but thats the extent of it.

You may not be feeding enough protein. Shrimp will turn cannibalistic if not fed enough protein in diet.
They dont need a lot- but they need some.

Yeah, I'll rarely advise anyone to feed shrimp more, but in this case you need to -or occasionally change the food up. I have true Amanos and have seen them predate on babies and I feel sure they have taken larger ones than I've been lucky enough to witness. I keep Fluval Bug Bites (the sticks for algae eating fish version is still pretty high protein) just for the Amanos and it seems to scratch that itch though I'd bet they still occasionally hunt.

Nothing good happens fast in an ecosystem.

Thanks guys, I started feeding more protein, and they seem peaceful now.
