Description

Entity 13HRP – 0010, called The Fish Tank, is one of the most unsettling anomalies studied by the Hollow Reality Project. From a distance, it looks like a tall, thin humanoid, but its body carries fish-like traits that do not fit any known life form. Its torso and limbs are long and slim, covered with blue-green scales that shine faintly under light. Along its ribs and neck, thin gill slits open and close, releasing mist even when no water is present. Strangely, the gills keep working without immersion.

The head is its most disturbing feature. Instead of a skull, the entity has a clear tank-like vessel filled with swirling liquid. Inside floats a large brain, glowing faintly with shifting colors. The light pulses match the being’s emotions and thoughts. Tests show brain activity far beyond any recorded human or animal. Electroencephalograms reveal multiple waves firing at once, suggesting thought patterns outside normal time.

Genetic tests add more mystery. Skin samples refuse to stay stable. Sometimes the results show partly human DNA, other times they look closer to octopus, and hours later the same sample reads as unreadable. Researchers now believe the material changes itself when studied, adapting against observation. This supports the idea that The Fish Tank comes from another dimension, one where biology follows different rules than Earth or space.

Mind and Communication

The Fish Tank’s most defining trait is its telepathy. Unlike other anomalies that send broken or unclear signals, it speaks with structure and clarity. It calls itself a traveler, saying it belongs to no single world or timeline. In talks with researchers, it answered complex questions with ease, even solving the long-standing “Hollow Causality Knot” in minutes.

Yet the entity also shows restraint. When shown the Book of Dead Gods, it pulled away, refusing to engage. Instead, it wrote a warning: “He who knows will lose oneself.” This reaction showed both awareness of danger and a moral choice to avoid spreading harmful knowledge. Researchers now see that The Fish Tank follows a kind of ethical code, guarding against truths too damaging for people to know.

Movement and Energy

When placed in water, the entity moves with impossible speed, creating spirals that break the rules of physics. Tracking devices fail within seconds, caught in repeating loops. On land, however, it moves slowly and heavily, as though Earth’s pull drags it down. Even so, it still moves well enough to escape normal restraints.

The Fish Tank also gives off energy pulses. Underwater teams reported bursts of sound and light coming from its body. Machines nearby shut down, screens froze, and drones spun out of control. People who stayed close reported headaches, dizziness, voices in their head, and brief visions of strange shapes. These symptoms fade but leave lasting tiredness. Some think these pulses are natural brain signals; others think they are messages aimed at beings outside our world.

Incident Report

During routine work, a leak appeared in its water chamber. At first, staff thought it was wear and tear. Later checks showed someone had cut the seals on purpose. Security found a technician with the tools used. Records proved the person tried to weaken the chamber, putting containment at risk. The breach not only threatened safety but also corrupted weeks of data.

Teams quickly sealed the chamber and removed the traitor. Leaders then increased monitoring, added backup systems, and set stricter checks to prevent insider attacks. Even so, questions remain: was this a lone act, a spy from another group, or proof that the project itself has been infiltrated?

Comparison and Risks

Studies show that The Fish Tank belongs to a group of mind-breaking entities. Unlike killers that attack the body, these beings attack thought itself. For example, Bella the Doll spreads memory loss, while the Mac Zurger Ad spreads endless hunger. By contrast, The Fish Tank spreads doubt and dangerous knowledge. This makes it more subtle but also more dangerous.

Interviews with staff show the risk clearly. Some began to feel unreal, saying they were “echoes” or “dream reflections.” Just talking to the entity may slowly undo the sense of self.

Conclusion

13HRP – 0010 – The Fish Tank combines impossible biology, unmatched thought, and otherworldly presence. It blurs the lines between human, animal, and unknown. It also warns against knowledge that can undo minds. Because of this, containment must protect against both physical escape and mental exposure.

The true danger lies not in attack but in the spread of ideas. By sharing forbidden truths, The Fish Tank could erase identity, history, and order. In this way, it is not just a living creature but a mirror showing the weakness of human thought. It remains one of the Hollow Reality Project’s most critical subjects, demanding constant caution in both action and belief.
