About the game
Aquarium Rainbowfish is a small expansion for Aquarium which features the special Rainbowfish. This expansion is a promotional expansion and it is not for sale. Rules for the Rainbowfish: The rainbowfish can be just be added to the deck but beware because they are pretty powerfull! The best way to use the rainbowfish is to give each player one at the start of the game instead of the normal fish of size 1. The rainbowfish is a fish of size 1 (so it eats only 1 unit of food each feeding time) but it's worth 1 extra star at the end of the game. The rainbowfish can be used as a fish of size 1 of one of the four colours so it makes it easier to score your bonuspoints at the end of the game (if you keep it alive till then!) or can be used to start an early breeding tank (but then you won't profit from the possible extra stars)

Questions and answers
Aquarium: Rainbowfish supports 2–6 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Aquarium: Rainbowfish is 45 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Aquarium: Rainbowfish for ages 8 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Aquarium: Rainbowfish has a complexity rating of 1.5 out of 5 from BoardGameGeek players, which makes it a light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
Aquarium: Rainbowfish belongs to these categories: Card Game and Expansion for Base-game. Its main mechanics are Set Collection and Simultaneous Action Selection.

The catalogue lists Aquarium: Rainbowfish as an expansion for Aquarium.

Check that your edition of Aquarium is compatible, as some expansions were revised between editions.
