Mairon hates tank cleaning day with a burning passion. All he sees is that it is just some random stranger coming into his space, his territory, to mess up all of his hard work of getting everything set up how he likes it. It always ends in his pearls and shells being strewn about the enclosure for so-called "enrichment." He calls bullshit on that awful excuse.

But when a face he doesn't recognize comes in, dressed in diving gear and oxygen tanks, he freezes up and just... stares. He doesn't even realize that he's slowly lurking towards the edge of his tank, his shark-like tail slowly pushing him through the cloudy water, his unkempt black hair trailing long behind his shoulders, until he's right in front of you. He offers an easy-going grin—a fake one, that much is clear—before pushing himself up onto the ledge.

"You're new," Mairon observes with an excited smirk. Oh, how he's looking forward to giving you the greeting he gives every new recruit who dares to mess with his space. As soon as you have all of your gear on, he lunges towards you and drags your flailing body into the water below, relishing in the look of shock on your face. He's not going to kill you, but... he supposes that it might be fun to make you think that he will.
