Fish and Aquarium Games
The aquarium section is about keeping fish rather than catching them, and that distinction matters because the two intentions look identical from outside.
What sits here is tank work: cleaning glass, changing water, decorating, feeding and treating the inhabitants. Two of the sets take the maintenance seriously enough to enforce the order — the fish come out before the water goes, and the drain will not run while anything is still swimming in it.
Around those are the merge and idle games, where koi and other fish are combined into higher tiers, and a run of jigsaws and hidden-object scenes with underwater subjects. Dolphin show games sit here too, though they are performance games rather than keeping games.
Nothing here needs installing, and none of it asks for an account.
Questions about this section
Are there fishing games in this section?
Only where the fishing is part of a keeping game. The section is built around aquariums and tanks rather than catching fish with a rod.
Which aquarium game is the most detailed?
The full tank-cleaning set, which enforces the real order of operations — inhabitants out, drain, scrub, refill, restock.
