simple and pleasant but I do wish there was more information given on the fish. itd be nice if you could see the variants of the fish youve gotten (like painted or golden) and their baby forms in their info cards and stuff like if they have the schooling behavior or not. the ui is also a bit janky in places (like trying to scroll through the list of fish in your tank, or how you cant change the ranking like from high-low to low-high) but overall it's just a nice simple fish game

This game was a pleasant surprise. Basically, buy some baby fish, feed them, then sell the ones you don't want and keep the ones that you like or that earn the most money. Upgrade your tank substrate, add decorations, etc. Ads are minimal. besides the optional ad to double your login earnings, I saw maybe one other ad. I ended up buying the ad free package anyway to support the developer. If you want something low-stakes and low-pressure that you interact with a couple times a day, get this.

Decent execution of the idea, but ad-heavy. 4 out of 5 times I open the app it automatically has an ad at the ready less than 10 seconds in. Doubling offline income lines up 3 ads. I understand needing to fund your app, but sometimes it's too much. And you can't get income from multiple tanks at once, so you better put your most expensive fish in one tank, and leave the trash in the other(s).
