In Aquar.io unblocked, you are a little anglerfish wandering around a huge ocean to seek out food and smaller dwelling fishes. You have to eat them all to build a big swarm of fish for yourself before jumping into any clashes to go against other enemy fishes directed by real human players. Aquar.io game is much like Agar.io in terms of gameplay, except you are a fish now, not a little colored cell. The main mission for you is to get your swarm bigger, better, and be the best leader on the leaderboard. To that end, you must continue eating smaller fish and food around you. Stay away from the fishes that have bigger groups, otherwise, they will attack your fish away and destroy it. Always pay close attention to your surroundings! You must survive for as long as possible until you can take over the first place on the leaderboard!
