You were invited to be part of Andrew's yearly Predator & Prey party. This year was feral freshwater fish get eaten at the local aquarium by aquatic predators; be it feral or anthromorphic. You were to be one of the feral fish. You were excited to be a feral fish. And strangely being eaten at the end of the night sounded like a great way to go out. You arrived at the local aquarium in nothing but your underwear as instructed by the invitation & you meet by the host of this Andrew himself. He gave you the feral rainbow trout Animal Costume you'd wearing the party as he lead you to the top entrance of the aquarium tank. You saw alot of freshwater fish swimming around in the tank. Obviously other Animal Costume Users. You removed your underwear & put on the feral rainbow trout Animal Costume all but the head. You were informed once you got it on it would (of course) near instantly transform you into a feral rainbow trout. It was also specially made to 'Seal' you. You jumped into the water & said to Andrew "I'm glad that you invited me to be a fish." Andrew reminded you "You will be eaten by one of us that chose to be a predator animal. "Will you be one of the predators yourself Andrew?" You asked curious. Andrew with a smile answered "Of course." Your reply to that was "I hope you are the predator that eats me. But I suppose I won't ever know if it was you. Kinda don't really want to know actually." You then flipped the costume head over your own. You instantly transformed into a feral rainbow trout. You focused on getting in touch with the simple fish you now were. You felt the simpleness of being a fish come into your mind & you embraced it. You began swimming around with all the other fish. You were now a simple fish. As the night went on you saw everyone through the glass of the aquarium partying. To you simple fish this was unimportant to you. Then there was an announcement by Andrew. "It's midnight. Time to be aquatic predators & feed on the fish in the aquarium as only true aquatic predators can & do." Everyone left the room & a few minutes later you heard voices above you. You looked up to see them finishing putting on aquatic predator-looking Animal Costumes. Soon they started jumping in & you began to see various aquatic predators in the tank with you now. You looked at the other feral freshwater fish & you all knew it was time to be hunted & devoured by the predators. You all prepared yourselves mentally to be simple fish trying not to be eaten. You didn't want to disappoint you host by just letting yourselves be eaten you easily. That wouldn't be fair to them. They chose to be predators to eat you as a feral fish. They should get to true predators by having to hunt & catch you to eat you. They want the full predator & prey experience as do you all you fish do.
So the predator & prey part of the party began.
