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.

Closest Match Closest MatchThe most similar game to the anchor, by what players say.
CollectathonCreature CollectorIdler
$7.49 ~43.5 hr median no co-op complexity: light 96.1% of 4k
The Squirrel's verdictHatching, breeding, and player-to-player trading replace card-pack RNG as the path to a full collection. Fish can also be bought from other players using currency earned in-game at no cost. At $7.49 with a median 43.5 hours played, it suits players who want control over which species they acquire while keeping the relaxed aquarium atmosphere and decoration options.
Not for you if the randomness of opening packs is the part you enjoy, since progression here comes from breeding and trading rather than loot pulls.

IdlerFishingCreature Collector
Cozy CozyLow-stress and wholesome — a game to unwind with.
$2.99 ~163.9 hr median no co-op 97.2% of 3k
The Squirrel's verdictA fishing minigame structures the collection loop: cast, catch, earn currency, unlock creatures, let idle income run in the background. Character customization and multiple fishing spots add variety. The 163.9-hour median playtime reflects a long completionist grind, though higher-tier catches require manual attention even after fully upgrading automation. At $2.99, the entry cost is low.
Not for you if you want a fully hands-off idler, since top-tier catches require manual intervention regardless of upgrade level.

Immersive SimCreature CollectorIdler
$24.99 ~19.3 hr median no co-op complexity: light 93.3% of 624
The Squirrel's verdictActive husbandry is the core here: fish need feeding, tanks need water changes, and neglect causes losses — one reviewer left for three hours and returned to a decimated tank. There are no card packs, no idle income, no shrimp. At $24.99 and a median 19.3 hours played, it suits players who want hands-on tank management with real upkeep stakes rather than a passive collection loop.
Not for you if you want species unlocked through card-pack randomness and income that builds without active attention.

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.
