It’s honestly one of the MOST realistic and enjoyable aquarium games on the App Store. You can tell the developers put a lot of thought and care into the details, and it really shows in how the fish look and how the aquariums function. It’s relaxing, fun, and clearly made by people who care about the experience!! Overall though, this is an amazing game and my favorite on the App Store. Thank you to the developers for creating such a great aquarium experience. ### 4/5 — Great Promise- potential changes *2026-08-01, version 1.9* Phenomenal game for the most part. I love the structure and atmosphere in this iteration of Fish Farm. I’ve played since the first release. The in-game pop up ads every three minutes are a bit much, but I’m glad they’re relatively short. My main gripes are that recolored fish should produce other recolored fish when bred with one another instead of having to use gems every time. And most importantly, the controls for the Eat Fish game are too unstable. The joystick’s position, at the lower righthand corner, is a setup for issues with finger slipping offscreen. Please help a loyal customer. I really do enjoy and appreciate your games. I have always support monetarily. ### 5/5 — アクアリウム *2026-07-28* とりあえず、癒されるし見てるだけで楽しい笑 ### 3/5 — App Store issues *2026-07-27, version 1.9* Can’t really see the food you drop. Can’t upgrade tank sizes so have to start over when you want a bigger tank. CAN’T LIMIT NOTIFICATIONS very very annoying (eggs hatched, fish are hungry, fish are grown). The 3D aspect doesn’t help much and looks worse for jellyfish tank (compared to Fish Farm 3). Fewer sustainability features are available by playing, and require monetary purchases. ### 4/5 — Great Promise- potential changes *2026-07-06* Phenomenal game for the most part. I love the structure and atmosphere in this iteration of Fish Farm. I’ve played since the first release. The in-game pop up ads every three minutes are a bit much, but I’m glad they’re relatively short. My main gripe is that recolored fish should produce other recolored fish when bred with one another instead of having to use gems every time. Most importantly, the controls for the Eat Fish game are too unstable. The joystick’s position at the further lefthand corner, it’s a setup for issues with finger slipping offscreen. Please help a loyal customer & fix. Lastly, I really do enjoy and appreciate your game. I will always support monetarily. **Developer response:** Thanks for supporting the series since day one! Here is the info on your gripes: Joystick: The joystick can be placed freely. It can be fixed in a position or reposition itself with each click. Colors: In FF4, you cross-breed general species, not your specific specimen. Because of this, you don't need to actually own a fish to breed it. For cross-breeding, color inheritance is therefore impossible. However, we might consider it for normal breeding. Ads: The short ads keep the game free to play, but an ad-removal purchase is available. ### 4/5 — Good but… *2026-07-02, version 1.9* Amazing graphics. It would be nice to exchange gems for Xp, and reverse currency exchanges such as coins for gems and gems for coins. ### 1/5 — Absolute Klasse *2026-06-22* Entwickler sind nur auf Steine aus !!!! Geldgier. !!!! Habe fast hundert Euro hier ausgegeben . Habe 20 Aquarien , kann in jedem nur noch 1 Fisch 🐠 einquartieren 🤮🤮🤮 NICHT LADEN !!! **Developer response:** Möglicherweise liegt ein Bedienungsfehler vor, da jedes Aquarium eine Kapazität abhängig von der Größe hat. Ein Becken, in das ohne Probleme 25 kleine Fische passen, kann durchaus nur einen Riesen-Fisch beherbergen. In Becken maximaler Größe passen aber auch mehrere Riesen-Fische. ### 5/5 — Greatest Aquarium \ Fishsim Game on the market, keep going! 👍👍 *2026-06-18* Congrats! Here are some ideas for add-on’s 1. More coral types with different patterns and colors plus growing and spreading 2. Saltwater invertebrates, like sea stars, shrimps, seahorses, sea needles, octopuses (these will be definitely difficult to animate), sea snails all in different muster and able to grow 3. Freshwater invertebrates, shrimp, some different muster for fish like goldfish and betta fish 4. Plants for freshwater like bottom plants creeping and spreading on the bottom of the tank and also floating plants for the surface 5 Plants for saltwater or better said algae, like green and red algae, seaweed also. Keep up the good work! ### 5/5 — Awesome game *2026-06-17* This has to be one of the best aquarium games i have found, the 3D graphics make it an amazing game…Being able to turn the tank around and see it from all sides like a real aquarium makes it the best, Love it! **Developer response:** Thanks for your review! ## Frequently asked questions about Fish Farm 4 ### What is Fish Farm 4?
