## What is FishFish?

FishFish: Cozy Aquarium is a relaxing idle aquarium game about slowing down, raising fish, and watching your little underwater world grow.

Open the game anytime to enjoy gentle fish swimming, soft water effects, calming music, and a warm hand-painted style. Your aquarium continues earning coins over time, so even a short visit can help your underwater world become a little more lively.

Feed your fish, keep the water clean, collect coins, and choose which new fish, plants, or decorations to add next. Each small choice helps shape your aquarium—a few more fish, a new plant, clearer water, or another step toward completing your collection.

### 4/5 — Plants and decor can’t be moved?

*2026-09-05*

Super cute, coins only generate if you have the game open which is fine cuz it’s fast. Only real issue I have is once you place a decoration or plant, it’s permanent. Unless there’s a way to remove them and rearrange but I haven’t figured it out yet

**Developer response:** Thanks so much for the thoughtful feedback! You’re right—coins currently only generate while the game is open. Offline earnings are something we’re considering for a future update.  
For placed plants and decorations, press and hold one to enter edit mode. You can then move, resize, rotate, change its layer, or return it to your inventory. We’ll also work on making this feature easier to discover! 🐟🌿

### 4/5 — Definitely cozy

*2026-08-25*

I absolutely love the graphics and backgrounds, very pleasant and beautiful! I like that it’s a very low stake game. I find it a bit silly that the driftwood in the plant combination also sways like the other plants and not like a piece of wood. One thing that I find annoying is the fish sizes, they aren’t very accurate. The guppies seem to be one of the biggest fish in the game, while others stay on the small scale. What I’m trying to say is that there is a wrong size ratio between the different fish. Otherwise great game :)

**Developer response:** Thank you so much for the thoughtful feedback and kind words! 😊 I’m really glad you’re enjoying the graphics, backgrounds, and relaxed style of FishFish.

You’re absolutely right about the driftwood — it shouldn’t sway the same way as the plants, so I’ll look into improving that animation.

I also really appreciate your feedback about the fish sizes. I’ll review the size ratios between different species, including the guppies, and make them feel more natural and consistent in future updates.

Thanks again for taking the time to point these things out. Feedback like this really helps me improve FishFish! 🐟🌿

### 3/5 — Needs sound effects

*2026-08-17*

Just started the game and not to impressed that it has an annoying theme music that once you turn it off there’s absolutely no sound. I bought a new area and it’s still just the same music. It’d be nice to hear ambient sounds based off where your tank is located and maybe the sound of water or something.

**Developer response:** Thank you for the detailed feedback! You make a very good point. Right now, FishFish’s audio is still quite simple, so turning off the background music can make the aquarium feel too quiet.

Adding ambient sounds such as flowing water, rain, nature sounds, and unique soundscapes for different tank locations is a great suggestion. I’ll definitely consider improving the audio experience in future updates.

Thanks again for helping make FishFish better! 🐟🌿
