Tank Theory

The goldfish had been alive for six years, which felt like both an accomplishment and an accusation. Sarah watched it circle the bowl on the counter, its orange tail flicking through water that hadn't been changed in three weeks. It kept swimming, kept eating, kept existing in its tiny transparent universe.

Her iPhone buzzed against the marble countertop. David's name lit up the screen for the third time that hour.

"Running late," she typed, though she wasn't running anywhere. She was standing still, very still, in a kitchen that cost more than her first three apartments combined.

The goldfish — named Fish, because their daughter had been four and not particularly creative — had survived Emma's childhood, Sarah's mother's death, and David's affair with the regional sales director. That one had lasted eight months. The goldfish had been alive for all of them.

"You're being dramatic," David had said last night, when she'd asked if he ever thought about what else he'd lied about. "You're making a bull out of a situation that doesn't even warrant a steer."

That was David's way: minimize everything, flatten its edges until it fit back in the box. Except boxes had dimensions. Lies didn't.

Sarah picked up her phone, scrolled through old photos. Emma's graduation. Their anniversary trip to Napa. A selfie from a company party where David's hand rested too familiarly on someone's lower back.

The goldfish rose to the surface, mouth opening and closing in tiny gasps.

"I know," she said aloud.

She'd read somewhere that goldfish had three-second memories, but that was bull — propaganda from people who kept things in tanks and wanted to feel better about it. Fish remembered. Fish learned. Fish survived.

Sarah opened her banking app, transferred half their savings to an account in her name only. Then she opened the notes app and began a list:

1. Lawyer

2. Apartment

3. Fish

The goldfish watched her through curved glass, its bowl distorting her face into something strange and new.

"Coming home," David's text read.

Sarah typed: "Don't."

Then she turned off her phone, placed it face-down on the counter, and reached for the fish food.
