Behind the glass, a microscopic lineage in living water.

AquaExpo is a real-time biotope simulation where you breed pure-line Neocaridina and Caridina strains, manage live water chemistry (TDS, pH, gH), and visit global breeders on your own 2D isometric expo floor.

Biological Life Cycle

The 5 sequential biological phases taking a microscopic hatchling to a champion exhibition ancestor.

1 0 - 7 Days
Baby Hatchling

Hatchling (Zoea)

Feeds exclusively on microscopic biofilm and powdered flora. Requires dense foliage shelter against filter flow.

Critical: Biofilm Density
2 8 - 21 Days
Juvenile Shrimp

Juvenile

Undergoes first molt cycles. Low calcium balance risks failed shedding; first phenotypic color pigments emerge.

Critical: gH & Mineral Balance
3 22 - 90 Days
Adult Breeder

Adult (Breeder)

Sexual dimorphism solidifies, females develop an ovarian saddle. Selective pairing rooms yield pure progeny.

Critical: Selective Pairing
4 90+ Days
Elder Shrimp

Elder (Grand Strain)

Peak carapace pigment density. Shrimps in this phase achieve the highest scores from expo judges.

Critical: Expo Jury Score
5 Eternal
Legacy Shrimps

Legacy (Hall of Fame)

Retired champions are commemorated in the Hall of Fame archive; their pure alleles are preserved across generations.

Critical: Pedigree Certificate

Role: Wild Expeditions & Mythic Morphs

Mendelian Genetics & Pure Line Law

Indiscriminate cross-breeding regresses colonies back into wild brown tones. Selective discipline unlocks legendary morphs.

LINEAGE TREE & BRANCHING SCHEMATIC F1 / F2 / F3
P0: Pure Foundation Stock Taiwan Bee Blue Bolt Boa Wild Type (Brown) Faded Common
Pure Line (Rare Morph)
Legendary Grade SSS
Wild Regression (Brown)

Pure Strain Dam + Pure Sire

Maintaining genotypic purity triggers recessive high-grade morphs (Taiwan Bee, Boa, Ghost Dragon). Each brood exhibits denser, porcelain-thick carapace coating.

Random Mixing & Wild Regression

Crossing red, yellow, and blue strains without isolated lines causes melanin dominance. Within a few generations, your colony reverts into transparent wild river shrimp.

Morphological Rarity Spectrum Estimated Mendelian Odds
Tier Sample Species Pigment & Carapace Coverage Incidence Rate
COMMON Red Cherry, Yellow Golden Semi-translucent shell, base pigment spread ~65.0%
UNCOMMON Blue Dream, Orange Sunkist Solid single tone, initial leg pigmentation ~22.0%
RARE Black Rose, Green Jade, Carbon Rili Dense opacity, masked pattern and deep chlorophyll green ~10.0%
EPIC Crystal Red / Black (Grade SS/SSS) Hinomaru & No-Entry motifs, thick porcelain-white base ~2.6%
LEGENDARY Taiwan Bee Boa, Blue Bolt Extreme, Ghost Metallic crown armor, spider leg banding, flawless symmetry ~0.4%

2D Isometric Expo & Live Market

AquaExpo is not a flat menu list. Navigate your avatar across an open isometric floor and personally inspect rival breeders' live display aquariums.

Personal Aquarium Booth

Lease a dedicated booth on the central plaza. Visitors can peer directly into your tank water, inspect your TDS balance, and examine your lineage pedigrees.

Walk to Marketplace & Auctions

Walk straight from the southern arch into the Petshop Hub or the central Auction Totem to bid on champion breeding pairs directly from their breeders.

Real-Time Multiplayer & Chat

Walk simultaneously with online breeders, spot active 🟢 online status indicators, and talk via real-time speech bubbles as you tour the floor.

Social Booths & Synchronized Competitions

Leave a 1-like-per-user tribute on favorite aquariums, send direct PMs to booth owners, and enter championships evaluated in real-time by judges.
