Fish Tank 2: Endless Night
Active-idle fish auto-battler with endless runs, synergies, and powerful builds
About Fish Tank 2: Endless Night
Fish Tank 2: Build an unstoppable fish army, discover powerful synergies, and survive endless nights in this active-idle roguelite auto-battler where your aquarium becomes a battlefield.
Your fish fight automatically in real-time, but victory depends on constant tactical decisions. Every run is a fresh challenge where you decide what to spawn, when to swap, and which buffs will define your build. Whether you play actively or idle briefly, your tactical choices determine your survival.
No two runs are ever the same - experiment with different fish families, buffs, and talent trees to discover overpowered builds.
