Been using 3D Aquarium Live Wallpaper for a couple months now. It’s basically an app that lets you turn your phone’s background into a 3D aquarium with fish swimming around. Pretty solid if you’re into that kind of thing.
Here’s what you do: you can pick from different aquarium themes and layouts, and the fish and plants all move around realistically. And there’s also a special keyboard that matches the aquarium, which is a nice touch. And you can adjust the animations and stuff – took me a while to figure that out but it’s useful.
Look, if you’re into customizing your phone and making it look cool, you’ll probably like this. It’s not perfect – the ads can get a little annoying if you don’t pay – but overall it does the job. Worth checking out.
