From Press Release:
Toronto, Canada – July 21, 2026 – Fellswell today officially announced Loopquarium, an aquarium roguelite coming to PC via Steam. Blending deckbuilding with aquarium management, Loopquarium scratches two very different itches at once: the cozy calm of caring for a fish tank, and the escalating chaos of protecting it from whatever lurks at night.
What begins as a peaceful little aquarium quickly becomes a scramble for survival. Summon fish from a growing card collection, grow the population, and collect coins to spend when the shop opens. Predators hunt, gather resources, and defend the tank. Prey keep the ecosystem thriving with unique abilities of their own. Keep the aquarium in harmony through the day, because when light fades, unexpected threats rise and turn things upside down.
As trouble bubbles up from the depths, success depends on discovering clever combinations such as pairing fish with complementary abilities, harnessing water currents, and finding enemy weaknesses. A loadout of persistent items and pets shapes the opening strategy of every run, but each addition raises the Depth Meter and unlocks tougher challenges. Race to find the three egg pieces and escape, or continue into Endless Mode to face even bigger challenges, including legendary encounters such as Poseidon. Will you flourish or flounder?
