Aquariums are the main focus of Marine Life Exhibits inTwo Point Museum, and thanks to the wide variety of fish that you’re able to collect from the Two Point Sea, they’re highly customizable. Depending on your budget and floorplan, you can have everything from small Aquariums with a few tiny fish, to massive tanks housing enormous creatures of the deep.

Aquariums are one of the more complex Exhibits to build and maintain, but once you’ve set up an ideal ecosystem for your fish they’re one of the most efficient ways to generate Knowledge, leading to great reviews from your guests.

Aquarium Size And Fish Needs

The minimum size for an Aquarium in Two Point Museum is4x3spaces, but you can build them larger than that as long as they fit inside the building where they’re housed. The larger the Aquarium, the more fish it can contain. A larger footprint also meansmore guests can view it at a time, and it is easier to get within range ofInfo Stands andDonation Bins.

How Many Fish Can An Aquarium Hold?

A minimum-size Aquarium of 12 tiles can hold up to 3 fish. The tank’s capacity will increase byapproximately one for every three additional spaces added to it, but that’s not an exact measurement; we built out an Aquarium adding one block at a time, and here’s what we found:

As you can see, it’snot quite one fish per three additional tiles, but it’s close enough that you can use that as your guide when building or expanding an Aquarium.Ultimately, a tank’s capacity is only limited by its size.

Remember,larger fish take up more space, counting as two or more toward the tank’s maximum population. you’re able to see a fish’s Size, which determines how much space it takes up, on theupper left corner of its window when examining it.

Filter Power

An Aquariummust have at least one Filterbefore you can complete construction; the game won’t let you finish the build without one. Filters keep the water clean enough for the fish in the Aquarium to survive, andlarger tanks may require multiple Filters.

Each fish addsMessinessto the tank from its body waste, natural toxins, and other factors, that Filters scrub out. A fish’s individual Messiness can be checked on their stats, but in generalbigger and more exotic fish have a higher Messiness rating.For a tank to be healthy,its total Filter Power must exceed the total Messiness of the fish housed inside.

Lots of Aquarium Decorations add a small amount of Filter Power as plants naturally scrub out algae and microbes - that’s something to bear in mind when designing a new tank!

If an Aquarium’s water turnsa sickly green, it doesn’t have enough Filter Power. You need to eitheradd a new Filter,orupgrade an existing one, before the health of the fish starts to decline. Filters that go too long without maintenance will break down, endangering your fish if they aren’t reparied quickly.

Food

Fish require eitherFlake FoodorFresh Food, which can be given to them via the appropriate type of Dispensers. Dispensersmust be periodically refilled by a Marine Life Expert; upgrading them extends the amount of time needed between refills. Fish that don’t have access to food, either because their feeder is empty or because they don’t have access to one of the appropriate type, willlose health and eventually die.

It’s possible to have fish that eat both types of food in the same tank, provided you have a Dispenser for each, butwatch out for fish with the Pescetarian trait;they willeat smaller fishunless their prey has a defensive trait of their own!

Temperature

If an Aquarium has a Heater, it can house Tropical Fish. If it has a Coldwater Cooler, it can house Coldwater Fish. If it has neither, it can house Temperate Fish. Putting fish in an Aquarium with the wrong temperature will eventually kill them, so be careful not to mix species with different environmental needs.

How To Breed Fish In Two Point Museum

In the third chapter of the Marine Life Museum storyline, you’ll gain access to theEgg Cup, which can be added to any Aquarium. Egg Cups are large and expensive at $15,000, but they let youbreed fish inside your Aquariums, expanding your collection without sending staff on perilous expeditions.

Fish only reproduce if they’re healthy, so verify the tank is clean and the Food Dispensers are kept full.

If an Aquarium hastwo or more fish of the same species, and an Egg Cup, then a new fish of that species will periodically hatchas long as there is available space in the Aquarium.If there are multiple species with breeding pairs in the same Aquarium, they all have a chance to reproduce.

Rarer and larger speciestake a longer time to breed than others, so consider having an Aquarium specifically for that purpose.

Fish bred at the museum have theSelect Specimentrait, whichincreases their sale value by ten percent.Keeping an empty space available in your Aquariums to keep breeding and selling new fish is a great way to supplement your museum’s income once you’ve fully analyzed every species in your collection!

Best Strategy For Using Aquariums In Your Museum

Aquariums can take up a lot of space, require a lot of maintenance, and thefrequent Expeditionsneeded to fill them with exciting specimens make them an expensive addition to the museum. If you use them effectively and play to their strengths, though, they’ll prove themselves well worth the effort by bringing in tons of donations.

First off,build other Exhibits near your Aquariums.Even something as simple as a Marine Life-themed Interactive display will help draw crowds and donations. You could even set up Exhibits from another category entirely, since Aquariums don’t care about Decorations outside their walls and vice versa.

Aquariums can also havewall speakersmounted on the outside of them, allowing you toeasily play Marine Ambience over a wide area nearby. Guests get the full Buzz of every fish in an Aquarium they view, so that ten-percent bonus from the music can be a big boost.

The biggest advantage that Aquariums have, though, is that they’reexceptional at stacking Info Stands with Knowledge.If a tank is full of small fish that have been fully researched, its Knowledge rating can easily reach the double-digits. Multple tanks like this in a single room can make some exceptional Info Stands that will be appreciated by Professors in particular; try running a Marketing Campaign to bring in Professors, sincethey donate based on Knowledge rather than Buzz, or use aDNA Designerto turn existing guests into Professors. Or both!

Strike a balance between “display tanks” and “breeding tanks.” You should definitely have both, but breeding tanks will never be at full Buzz since you’ll be constantly selling off or analyzing newly-hatched fish.

Remember to place yourFood Dispensers, Filters, and Heaterswithin easy reach of the Aquarium’s airlock, so that your staff can get to them quickly and efficiently. That goes double for tanks containing Sea Monsters, who usually have adverse effects on staff trying to take care of them!

Lastly, grouping several Aquariums in one large roommakes a fantastic Tour.Find an Eloquent Expert and keep them giving tours of your Aquariums, all of which will likely have Buzz ratings above 100, and you’ll start seeing rave reviews and generous donations.
