So here's my honest take on Aquarium Fish vs Alien. I've tested a bunch of mobile strategy games and this one's a pretty solid option. The core gameplay loop of managing your fish tank and raiding other players is addictive, and the clan battles add a nice social element. The graphics and animations are polished too. But it's not without its issues - the progression can get grindy at higher levels, and the ads can be annoying if you don't pay. Overall though, I'd say it's a fun casual game that scratches that strategy/virtual pet itch.

Description

Been playing Aquarium Fish vs Alien for a couple months now. It’s basically a virtual pet simulator with some strategy and puzzle elements. You start with a couple guppies in your tank and gotta keep them alive and thriving. The goal is to earn enough coins to buy these egg pieces and advance to the next level.

Here’s what you do: you gotta keep your fish fed and happy. There’s upgrades you can buy like better fish food and laser beams to zap the aliens that try to invade your tank. And you can join a clan with your friends – that’s where the real fun is, coordinating attacks and trying to take down other players’ bases.

Look, if you’re into strategy games and virtual pets, you’ll probably like this. It’s not perfect – the upgrade grind can get old after a while – but overall it does the job. Worth checking out if you want a casual game to play with your buddies.
