But you didn't do what I suggested. If you put them in and your fish ate them, that's absolutely normal. Fish are used to you putting stuff in the tank to be food for them. So when you put in the shrimp, they thought you were feeding them. Perfectly normal. Heck, my lion completely swallowed a small coral I dropped in the tank. Why? Because he was used to me dropping in food. What I said was to put in the shrimp late at night when your fish are asleep and triggers, once they're asleep, they won't wake up until the lights come on.
