The Glowing Tank

Mara had always felt the weight of unseen eyes, a sensitivity she’d inherited from her grandmother, who used to swear by the cold spots in their old farmhouse. Now, in their cramped two-bedroom apartment above a shuttered fishmonger’s shop, that weight had settled onto her chest like a stone. Her fiancé, Leo, slept soundly beside her, one arm draped protectively over their infant daughter, Elara, who lay between them. In the corner, their two-year-old son, Theo, was a tangle of limbs in his camping cot, his breath a soft whistle. The only light came from the new fish tank Leo had brought home last week, a glowing rectangle against the dark wall, its bubbles a rhythmic pulse.

They’d gotten the tank to soothe Theo, who had, until then, refused to sleep without the television’s flickering glow. Now, the tank cast shifting patterns of blue and green across the ceiling, like water ripples, and the kids had finally found some rest. But Mara had not. Every night, she lay awake, watching the bubbles, feeling a new presence in the room, one that was not the passive haunt of the upstairs neighbor who had died last spring, nor the unsettling attention of the entity she’d dubbed ‘the visitor’ in her previous journal entries. This was something else, born from the water’s constant motion.

It started with the fish. The three guppies and the neon tetra, which Leo had chosen for their hardiness, began to dart frantically to the glass, their tiny mouths opening and closing as if gasping for air, though the tank was pristine. Then, in the morning, she found one floating belly-up, its colors dulled. Leo shrugged, blaming the tank’s cycling process. But Mara felt a cold dread, because in the night, she had heard a soft, wet sound, like a tongue tapping on glass, and when she’d turned, she saw a shadow pass over the tank, and the light briefly dimmed, as if something had eclipsed it.

By the third night, the fish were all dead. The tank now held only water and the hollow, green glow of the filter’s LED. That night, as Leo snored and the children dreamed, Mara watched the empty tank, and the water began to move on its own. It swirled, then stilled, and a face pressed against the glass from the inside. It was gaunt, with eyes like voids and a mouth stretched in a silent scream. It was the old woman from her previous stories, the one she thought had been banished. But now she was here, in the tank, her long hair floating like seaweed, her hands pressed flat against the glass, leaving no fingerprints. Mara froze, her breath caught, and the face stared directly at her, and then it smiled, all needle-like teeth.

She wanted to scream, but she couldn’t. She wanted to wake Leo, but her limbs were lead. The face began to mouth words, and though no sound came, Mara felt them in her mind: ‘You forgot me, dearie. You thought I was gone, but I found a new home.’ The water grew murky, and the face dissolved into a swirling vortex, and then, a hand emerged from the surface, dripping, reaching toward her. It was gnarled, with long, yellowed nails, and it stretched, impossibly long, toward her face. She felt its cold, wet fingers on her cheek, and she finally screamed.

Leo jolted awake, and the hand retracted with a splash. The tank was still, the water clear, and the fish were still floating. ‘It’s nothing, love,’ Leo soothed, ‘just a nightmare.’ But Mara saw that the water level had dropped, and on the carpet beneath the tank, there was a single, wet footprint, too small for any adult.

The next night, she did not sleep. She watched the tank, and she saw the woman again, but this time, she was not alone. In the water, there were the shapes of children, their faces pressed against the glass, and among them, Theo’s. She gasped, and Theo’s image wavered, and she realized it was not her son but a thing wearing his face. It smiled, and the woman opened her mouth, and a torrent of black water poured out, flooding the room. Mara was submerged, choking, thrashing, and then she woke, gasping, in her bed. But the room was dry, and the tank was dark, the light flickering.

From then on, the tank was no longer a source of comfort but of terror. Leo didn’t understand why she wanted to get rid of it. ‘It helps the kids sleep,’ he argued. But she knew the truth. The old woman had found a new vessel, and she was growing stronger, feeding on the fear in the room. Mara tried to cover the tank with a blanket, but the glow seeped through, and the sounds grew louder: a gurgling, a slithering, a high-pitched giggle that made her skin crawl.

On the fifth night, she found Theo standing in front of the tank, his hands on the glass, his face lit from below. He was whispering something, and Mara crept closer, hearing him say, ‘Yes, Mama, I’ll do it.’ She grabbed him, and his body was cold, his eyes wide and unseeing. She shook him, and he blinked, as if waking from a trance. ‘What were you doing, baby?’ she asked, her voice trembling. He pointed at the tank and said, ‘The lady in the water says she wants to see you, Mama.’

In desperation, she poured salt in a circle around the bed, hung charms from the old neighbor’s closet, and recited every prayer she knew, but the presence grew. On the sixth night, Elara, who had never woken in the night, began to cry, and when Mara went to comfort her, she found the baby’s skin cold, as if she’d been dipped in water. The room smelled of brine, and the tank’s light was now a sickly green, pulsing like a heartbeat.

Mara knew she had to do something. She couldn’t afford to move, but she could end this. She remembered the old woman’s connection to water, and she recalled that in her previous stories, the woman had always come from a damp place. So, she waited until Leo was at work, and the children were napping, and she dragged the fish tank to the bathroom. She emptied it in the tub, the water rushing down the drain with a gurgle that sounded like laughter. She scrubbed every inch of the glass with vinegar and salt, and then she smashed it into pieces with a hammer. She bagged the shards and the filter and the dead fish, and she threw them into the dumpster behind the shop.

That night, the room was dark and silent, but Mara did not feel relief. She felt a cold draft, and in the corner where the tank had been, there was a faint, wet patch on the wall, spreading slowly. She watched it grow, taking the shape of a face. The old woman was not gone. She had merely been freed from the tank, and now she was in the walls, in the air, in the very cracks of the apartment. Mara heard a sound from the bathroom, and when she went to investigate, she found the toilet bowl filled with black, oily water, and a single strand of long, gray hair trailing from the rim.

She ran back to the bedroom, her heart pounding, and she found Leo awake, staring at the empty space where the tank had stood. ‘Mara, why is there a wet footprint on the pillow?’ he asked, pointing. On Elara’s pillow, there was a perfect, miniature footprint, as if a child had stepped there with wet bare feet. But Elara was in her crib across the room, and Theo was in his cot. Their own feet were bone dry.

That was the night Mara realized that no matter what she did, the old woman would always find a way. She was not a ghost of the past; she was a creature of the water, and water always finds a way back. The apartment grew colder, and the dampness seeped into their bones. Leo finally agreed to move, despite the financial strain, but they couldn’t afford a deposit on a new place yet. In the meantime, Mara kept every light on, and she watched the corners, waiting for the inevitable.

A week later, they bought a new tank, smaller, with only a single betta fish. Leo thought it would cheer them up. But on the first night, the betta jumped out of the water and lay gasping on the carpet, and when Mara scooped it back, she saw that its eye was milky, and it floated on its side. That night, she heard a knock on the front door. She opened it, and no one was there, but on the mat, there was a wet, crumpled photograph. It was a picture of the old woman, sitting in a rocking chair, holding a baby wrapped in a blanket, and the baby’s face was that of Theo, and the old woman’s smile was not a smile but a gaping black hole.

Mara looked up, and she saw a reflection in the glass of the door. It was not her own. It was the old woman, standing behind her, her hand reaching out, and Mara realized with horror that the reflection was not in the door but in the water that now pooled around her feet, spreading from the kitchen where the sink was overflowing. The water rose, and in it, she saw not only the old woman but the forms of her children, their faces pale and lifeless, floating like the fish. She screamed, and the lights flickered, and the last thing she saw was the tank’s glow, now a bloody red, before the water closed over her head.

She woke in a cold, purgatorial silence, standing on a wet tiled floor, in a room that was not her own. There was a glowing tank in front of her, newly cleaned, with a single fish swimming in lazy circles. She pressed her face to the glass, and she saw her own reflection, but she was not looking out; she was looking in. And on the other side, her family stood, their faces pressed against the glass, their mouths moving in silent screams, and she knew, with a sickening certainty, that she was now the one in the tank, and she would be the one to torment them for years to come.
