You own a peaceful deep‑sea world. Your aquarium is home to various colorful fish. You can feed, pet, name, and breed your fish. Through the shop, you can expand your tank, buy decorative chests, and unlock special scenery items. Every fish has a unique gene combination (body shape, pattern, tail fin, colors). When breeding, offspring can inherit or mutate into rarer traits. You can also freely drag and drop decorations on the seabed to create a one‑of‑a‑kind aquarium.

How to play Deep Sea Fish Scene?

1. Fish Ecology & Raising

- Life cycle: Each fish starts as a fry. Feeding increases its fullness – exceeding 100% can trigger a breakthrough and evolve genes. Reaching 100% growth makes it an adult.

- Adult fish drop "Pearls" (the in‑game currency) over time. Pearls are used to buy items in the shop.

- Click a fish to open its info panel. You can see its gender, growth stage, gene profile, rarity score, and customize its name.

- Double‑click a fish to interact – the fish will dash around playfully.

2. Feeding System

- Tap/click anywhere on the water surface to drop a piece of fish food (consumes one food item). Nearby fish will swim toward it and eat.

- Food efficiency can be upgraded in the shop (Premium Nutrition Food), increasing satiety recovery.

- Smart auto‑feed (hidden feature – long‑press the settings button to unlock) automatically feeds a hungry fish every 2 seconds.

3. Economy — Pearls, Fish Food, Breeding Cards

- Pearls: Main currency. Dropped by adult fish, gained by releasing fish, opening chests, etc. Used to buy shop items.

- Fish Food: Used for feeding. Can be bought or automatically generated by special decorations (e.g., "Everlasting Kelp").

- Breeding Card: Required for two adult fish to breed. Can be bought or automatically generated (e.g., "Love‑struck Giant Clam").

4. Genetics & Breeding System

- Each fish has six gene traits: Body Shape, Pattern, Tail, Body Colors, Accent Color, Glow Color. Each gene has 4 tiers: Normal / Rare / Epic / Mythic.

- When two adult fish (opposite gender) are both ready to breed (cooldown over), you can spend one Breeding Card to start a romantic courtship ritual (animated sequence with floating dialogue bubbles).

- The offspring’s genes are inherited from both parents, with a chance to mutate upward (e.g., Normal + Normal → Rare, Rare + Rare → Epic). Certain combinations may even synthesize a Mythic gene.

- Each fish has a generation number – offspring generation = max(parent generations) + 1.

- After breeding, both parents enter a 60‑second cooldown.

5. Encyclopedia (Gene & Evolution Dex)

- Unlocked fish species are recorded in the Species Dex.

- Every new body shape, pattern, or tail fin you unlock is added to the Core Gene Dex.

- The encyclopedia shows your total collection progress, helping you track rare gene unlocks.

6. Shop

The shop offers:

- Expand Aquarium: Increases tank capacity by +2 (base capacity 4, grows with upgrades). Cost: Pearls.

- Normal Fish Food: 10 portions (Pearl cost).

- Mystery Fry: Instantly get a random baby fish (fry).

- Breeding Card: One card.

- Premium Nutrition Food: Upgrades food efficiency (cost increases with level).

- Epic Chest: Randomly gives one Epic‑tier decoration (plant, coral, shell, starfish, or sculpture) with unique appearance.

- Legend Chest: Randomly gives one Legend‑tier decoration that also grants a permanent global BUFF (e.g., auto‑collect pearls, auto‑generate food, auto‑generate breeding cards, growth boost, shop discount, etc.).

7. Free Decoration Mode

- Enable "Free Layout (Drag Mode)" in the settings. You can then drag plants, corals, shells, starfish, and other decorations with mouse/finger to reposition them.

- In this mode, selected decorations show a white dashed circle. Click the red ❌ or double‑click to delete the decoration.

- All position changes are saved automatically.

8. Golden Release Net

- Enable "Golden Release Net" mode. Then tap/click on the water – a net will shoot out, catch a fish, and bring it to the surface. Releasing the fish gives you Pearls (reward based on the fish’s rarity score).

- This feature is mainly used to release fish when your tank capacity is exceeded.

9. Special Decoration BUFFs (Legend‑tier)

Legend decorations provide permanent global effects, such as:

- Pearl Magnet Anemone: Automatically picks up dropped pearls.

- Breeding Sanctuary Coral: Greatly increases chance of inheriting high‑tier genes during breeding.

- Everlasting Kelp: Generates 1 fish food every 10 seconds.

- Love‑struck Giant Clam: Generates 1 breeding card every 60 seconds.

- Golden Blessing Starfish: Doubles the number of pearls dropped by fish.

- Growth Holy Water Branch: Increases growth speed of juvenile fish by 30%.

- Abundant Spring Algae: Slows down fish hunger rate by 20%.

- All‑encompassing Shell: Permanently increases tank capacity by +2.

- Rhythmic Sonic Starfish: Greatly speeds up jellyfish appearance.

- Merchant’s Token Pine: Reduces all shop prices by 10%.

10. Jellyfish Interaction

- Glowing jellyfish appear randomly in the deep sea. Tap a jellyfish to earn a small amount of Pearls. Tapping the same jellyfish 30 times makes it disappear.
