Reefling: A Cozy Desktop Aquarium

Reefling is a calm desktop aquarium that sits in the corner of your screen. Feed your fish with a click, earn shells over time, and collect over 150 pixel-art species. Decorate the tank and watch day turn to night. Your fish never starve and you can't lose, so just relax while you work.
