Great but not perfect. Very realistic graphics and the gameplay and progression loop is way better compared to fish farm 3. Only problems is there could be more mini games, there are some lags when there are 10+ fish, and the available creatures/deco items are limited for right now. I was hoping to see turtles, sharks, salamanders, etc though I see with the format it might be difficult. Anyway, I'm still hoping for them.

Thanks for your review! This is actually high-end graphics, so lags are usually device-dependent. Please try adjusting the graphics settings in the Settings menu to speed it up. As with FF3, we will be adding more creatures and species over time. If we waited to add all of them at the beginning, we would never be able to release ;-)

I like game for the most part but Filters for the tanks cost Waaaay too many Diamonds! Like the rate of what you earn to the cost just doesn't make sense. Its pretty clear they want you to feel forced to spend alot of real money, which some of us don't have. That's the only turn off for me. If it weren't for that I would say 5 stars all the way! Also the option to edit the bezels and style of lights on the Aquariums would be nice. For Example, make it bezelless or black. Huge potential here!

Love the detail and level of customization. This game is as close to having a real fish tank in your phone as it gets. I've managed to unlock plenty of things without spending a dime. It seems everything in the game is attainable for free if given enough time and attention. Love my fishies! (update, Dev team solved my issue the same day, 5 stars for gameplay, game quality, and support and service) (second update, now has forced ads at random that ruin the tranquility)

We’ve landed in the reality that only a few players spend money in-game. To support development, we’ve added interstitial ads at natural transitions and during longer tank viewing—so we can fairly monetize all players. Removing ads costs just around 7 cents a day—no subscription needed. Thanks for helping us keep the game going!
