Barracuda mer reader getting rescued and put into the care of a sanctuary run by the 141.
You'd been caught in a net, which had severely cut your tail and stunted your swimming slightly. It would be hard for you to survive in the wild, so they make the decision to keep you in the sanctuary.
You have to be in a tank by yourself, and there are warning all around your enclosure to remove all jewelry to avoid agitating you.
One asshole decided to use flash to take a photo of you, making you charge the glass and smack into it. John hauled the man out personally, shut down your enclosure for the day, and spent some extra time checking in with you in your tank.
You were a solitary hunter, and in order to keep your tail healthy and keep you mentally stimulated, Johnny feeds you live fish once a week. Watching you dart after your prey with such speed was quite exciting.
I don't know how to end this, I just think barracudas are really cool, and I was thinking about a barracuda mer. I will write more soon. Also, I just got back from out of town, so once my brain worms have had a moment to rest, I will be back to my usual filth >:]
