No revenue estimate for PSN — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $23.7K — a different platform, not this one.

Fantasy Aquarium

It’s your very own aquarium. Buy the fish you love, raise them from tiny fry, and watch them grow and flourish. Create your dream underwater world—calm, colorful, and completely yours. A relaxing idle experience. Your fish keep growing even while you’re away. Come back to see how your little world has changed and be pleasantly surprised. Slow down time and unwind. Let the gentle motion of the water soothe your mind as you enjoy the living world you’ve built with care.
