Aquarealm

Real-scale aquascaping: 98 species, 50 plants, 21 tanks, and a reverse mermaid who judges your layout, never you. All included. No subscription, no ads, no tracking.

Aquarealm is an aquascaping simulator where everything is real-scale. A 12-inch oscar really does fill a third of a 55-gallon. Six neon tetras really are that small. Watching one fish swallow your tank teaches more than any warning label ever could.

Build with stone, wood, and 50 live plants across 21 real tank footprints — from a 5-gallon nano to a 90P. Then stock it from 98 species: 80 fish, 10 snails, and 8 freshwater shrimp. Every one of them rendered at true adult size.

And Princess Magenta — a reverse mermaid, fish on top, glass legs below — will tell you exactly what she thinks of it.

TRUE TO SIZE Everything renders at 25.4 pixels per inch. Real tank footprints, real adult fish. The tank you're planning is the tank you'll get.

A COMPATIBILITY ENGINE THAT ACTUALLY KNOWS THINGS Predation by size. Fin-nippers versus long fins. Schooling minimums. Temperature and pH overlap. Snail-safety. Shrimp-safety — because a betta will absolutely eat your cherry shrimp. Stocking limits per tank. When your layout is wrong, Magenta names names.

PHOTOGRAPH YOUR REAL FISH Snap your own fish, shrimp, or plant side-on, crop it, and it swims in YOUR virtual tank. Drag your real livestock around and plan your real aquascape before you move a single rock or spend a single dollar. Your photos never leave your phone.

THE DEX — FISH, SHRIMP & PLANTS Every species you keep is logged forever. Photograph them to complete your collection, and enter the Fish Hunt or the Shrimp Hunt for a chance to be featured.

THE BREEDING CHECKER Pair any two and Magenta calls it: will they breed, will they hybridize, and exactly what water they need to try. She'll also tell you why mixing four colours of Neocaridina gives you a tank full of muddy brown babies.

THE WATER LAB Ammonia, nitrite, nitrate, pH, GH, KH and CO2 — each one named, explained, and judged in plain English. pH is scored on stability, not a magic number, because swings are what kill tanks.

POWER OUTAGE MODE Walstad-style math turns your plant load into days of filterless survival, with a shopping list of exactly how many bunches keep your fish breathing. Because the night the power goes out is not the night to start googling.

FEEDING, STREAKS & CONSEQUENCES Guess your tank's appetite. Overfeed and the water clouds. Underfeed and the babies go frantic. Keep a care streak and Magenta earns herself a new outfit.

TANK PERSONALITIES Zen Church Picnic. Absurdist Fight Club. Glistening Aero Paradise. Your tank's personality decides how Magenta reacts to what you've done.

MULTIPLE TANKS Unlimited tanks in the Fish Room. Each one remembers its own fish, plants, and layout.

VERDICT CARDS Every layout gets a score and one of Magenta's lines, stamped on a card built for sharing. Pride cards and roast cards alike.

MAGENTA'S GUIDES Seven of them, in her voice. Cycling. Acclimation. Planting. Breeding. What to do when the tank cracks at 2am.

21 OUTFITS Seventeen unlocked the moment you open the app. Four you earn by caring for your fish — because some things should be earned, sugar.

ONE PRICE. EVERYTHING INCLUDED. $9.99, once. No subscription. No in-app purchases. No ads. No tracking. No account. No internet required (except the fish-store finder, which you may never open).

Reef Rule Number One: Magenta judges layouts, never people.

A soft place for aquascapers, with love from a reverse mermaid.
