FishingIdlerCreature Collector
Cozy CozyLow-stress and wholesome — a game to unwind with.
$14.99 ~20.6 hr median co-op complexity: light 95% of 8k
The Squirrel's verdictCast n Chill is built around active fishing across maps with idle income layered on top, plus optional co-op. Where Chillquarium's progression comes from watching a tank fill passively, here the player casts, catches, and upgrades through play. At $14.99 with a median 20.6 hours, reviewers describe it as completable but short on replay value.
Not for you if you want a stationary tank to watch and a passive collection loop rather than active casting and map progression.

Tiny Aquarium: Social Fishkeeping
PCMacLinux
CollectathonCreature CollectorIdler
$7.49 ~43.5 hr median no co-op complexity: light 96.1% of 4k
The Squirrel's verdictSame core loop: raise fish, watch tanks fill, chase collection completion. Tiny Aquarium replaces card-pack RNG with hatching and breeding, adds decoration and player-to-player trading for currency you earn free, and lets you fish alongside others. Better fit for players who wanted control over which fish they got.
Not for you if you want the pack-opening randomness itself, since progression here comes from breeding and trading, not loot pulls.

Immersive SimCreature CollectorIdler
$24.99 ~19.3 hr median no co-op complexity: light 93.3% of 624
The Squirrel's verdictBoth put fish-keeping at the center, but the mechanics diverge: Chillquarium is card-pack RNG and passive income, Fish Game is active tank simulation with feeding, water changes, and real husbandry mechanics like filtration expectations. No shrimp, no card packs, no idle-money loop. Fits players who want simulation depth over collection gacha and don't mind hands-on upkeep.
Not for you if you wanted Chillquarium's passive card-pack collecting rather than active tank maintenance with feeding and water-change cycles.

IncrementalFishingMinimalist
Cozy CozyLow-stress and wholesome — a game to unwind with.
$4.99 ~5.6 hr median no co-op complexity: light 91.4% of 2k
The Squirrel's verdictFishing Inc shares Chillquarium's fish collecting and passive-income loop, but replaces card-pack RNG with direct clicking and upgrade trees. Progression is shorter and more linear, no gacha chase for a specific variant. At $4.99 with a median 5.6 hours, it suits players who want the fish-tank-capitalism feeling without an open-ended grind.
Not for you if you want the loot-box thrill of chasing a specific rare fish rather than a short, fixed upgrade path.

Creature CollectorIdlerFishing
Cozy CozyLow-stress and wholesome — a game to unwind with.
$5.99 ~23.7 hr median no co-op complexity: light 90.7% of 551
The Squirrel's verdictSame loop: buy card packs, unlock fish, wait for growth, sell or keep for passive income, chase full collection. Joyquarium is widely described as a close copy of Chillquarium's mechanics, with fewer decorating options and some missing QOL touches. At $5.99 with median 23.7 hours played, it suits those who've exhausted Chillquarium's packs and want more of the same loop.
Not for you if you want the fishkeeping charm and decorating depth reviewers say Chillquarium has and this one lacks.

Black Hole Fishing
PCLinux
IncrementalIdlerFishing
$5.99 ~15.4 hr median no co-op complexity: moderate 88.5% of 515
The Squirrel's verdictBlack Hole Fishing pairs fish breeding and collection with a prestige loop: you accumulate mass, hit breakpoints for meta-currency, and reset to repeat with more automation. Unlike Chillquarium's open-ended collection habit, the prestige structure gives it a defined arc. At $5.99 with a median 15.4 hours, late-game pacing and bugs are common reviewer complaints.
Not for you if you want purely passive collection without repeated resets that undo and rebuild progress each cycle.

EducationJob SimulatorCreature Collector
Cozy CozyLow-stress and wholesome — a game to unwind with.
$6.39 ~17.5 hr median no co-op complexity: light 83.9% of 1k
The Squirrel's verdictAquarist at $6.39 puts you in charge of a fish shop where you buy species and decor outright, place and arrange items manually, and manage tank conditions without any pack-opening mechanic. With a median 17.5 hours played, it fits players who want aquascaping and shop management. Reviewers flag placement controls and persistent bugs as friction points.
Not for you if you want species unlocks driven by chance rather than direct purchase, or prefer a polished, bug-free experience.

CuteLife SimNature
Cozy CozyLow-stress and wholesome — a game to unwind with.
$19.99 ~5.9 hr median no co-op complexity: light 84.5% of 400
The Squirrel's verdictFishery has you buy fish directly, manage water chemistry, gas levels, and plumbing, and breed species rather than drawing from packs. At $19.99 with a median 5.9 hours played, it suits players who want technically detailed tank simulation. Note that reviews indicate the game has shifted away from its original chemistry complexity toward a more decoration-focused experience.
Not for you if you want the passive income loop and randomized species unlocks rather than hands-on tank management.
