## What is Fish Abyss?

Build a thriving ocean sanctuary splashing with aquatic life - all while you listen to the calming sounds of the ocean as whale song echoes in a distant reef.

Hundreds of Fish to Collect

Discover all the fish in the sea and bring them to your aquarium. From koi and clownfish to majestic creatures that would never fit in your fish tank, such as dolphins, sharks and humpback whales and even more exotic species - we have them all to collect and grow at the tap of your finger!

The World’s Largest Fish Tank

Dive into the world’s largest fishtank - your own aquarium sanctuary! Customise your underwater oasis with corals, seaweed, rocks and attract new species of fish to your deep sea aquarium in this relaxing underwater sim.

Journey into the Depths of the Ocean

Begin your adventure in a secluded reef as you discover your way through the depths of the aquamarine world, one tap at a time.

Relaxing Gameplay

A relaxing family simulator game full of life, build your beautiful virtual underwater tycoon where marine life can thrive - all as you listen to the zen music of whale songs in a distant reef.

Real Schools of Fish

The marine life in your reef will find friends and form schools of fish, just like real fish majestically weaving in and out of the coral (and avoiding sharks!) using our advanced behaviour simulator.

Care for Your Aqua Pets

Create the ultimate fish farm. Hatch eggs and feed your underwater creatures to level them up. Merge your fish to breed them into more special, unique pet fish. 

Fish Abyss is completely free to play but some optional in-game items may require payment.

### 5/5 — Same reviewer back after a few years

*2026-04-26*

I really like how your game is. It still has pretty quality but the fish. I absolutely love them and I also have fish myself so the game just hits the spot top tier 10 out of 10 game

### 5/5 — I love the fishes

*2026-04-24*

This is the most beautiful game I ever played I would play it to calm down

### 1/5 — Unplayable past a certain point

*2024-03-30*

Money hungry and a bit dull after you’ve played it for a couple of days.
 Cannot progress without spending waaay more than the game is worth. 
Game developers clearly don’t understand mathematics. Not worth investing time or money in.

### 4/5 — Sting rays

*2023-12-17, version 1.0*

It’s entertaining but it’d be cool if they had string rays as an option!

### 5/5 — Amazing

*2023-12-08*

This Is absolutely amazing there is one thing though… it’s a little boring. When I saw it on the App Store I thought you would get to be a fish your self and you could go anywhere you wanted 😢. That’s all!

### 5/5 — Keep coming back to this game. It has been years!

*2023-11-27*

Very Nice.

### 3/5 — Wolf tail

*2023-11-11*

I was wondering since I looked at the other games you made I want to play them but since I have a I pad I don’t know what size it is and I was wondering if you can please update it so I can play since I only downloaded this game and I really love wolves then anything

### 2/5 — Beautiful but expensive

*2023-06-04*

When I first opened this game I was stunned by how beautiful, realistic and peaceful it was. However, it’s impossible to breed fish beyond a certain level without spending huge dollars. Compared to other games the amount of gems and the cost is astronomical.

The very low reward for achieving goals and levelling is downer as well. If the rewards were higher there would be more incentive to pay money on bonus’s etc. but the two simply don’t balance out.

Very low reward - very high cost for bonus etc.

 I don’t mind spending a little money on a game I enjoy but for this one it is just not feasible. The cost factor and low reward is why I have rated it so low.

### 5/5 — Best game

*2023-05-29*

Beautiful graphics amazing quality and no ads! Also really smooth and fast

### 2/5 — Beautiful but $$$

*2023-05-27*

One of the nicest looking aquarium games but be aware that progression quickly becomes impossible without paying a significant amount of money. The pricing is also such that to have enough gems for stuff, you’ll need the next tier. For example, the cheapest chest is 5000 gems and you only get 4800 gems in the cheap gem pack.

The gems are not cheap. Exponential scaling of costs for fish & plants but in-game resource generation doesn’t match up. I’d like to rate it higher but looking good isn’t enough - the economy of the game needs a complete overhaul for this to be a playable game.
