Aquariums are the main focus of Marine Life Exhibits in Two Point Museum, and thanks to the wide variety of fish that you can 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.

Everything you need to know about the Archaeology course in Two Point Campus.
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 is 4×3 spaces, 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 means more guests can view it at a time, and it is easier to get within range of Info Stands and Donation 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 by approximately 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’s not 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 can see a fish’s Size, which determines how much space it takes up, on the upper left corner of its window when examining it.
Filter Power
An Aquarium must have at least one Filter before 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, and larger tanks may require multiple Filters.
Each fish adds Messiness to 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 general bigger 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 turns a sickly green, it doesn’t have enough Filter Power. You need to either add a new Filter, or upgrade 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 either Flake Food or Fresh Food, which can be given to them via the appropriate type of Dispensers. Dispensers must 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, will lose 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, but watch out for fish with the Pescetarian trait; they will eat smaller fish unless 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 the Egg Cup, which can be added to any Aquarium. Egg Cups are large and expensive at $15,000, but they let you breed fish inside your Aquariums, expanding your collection without sending staff on perilous expeditions.
Fish only reproduce if they’re healthy, so make sure the tank is clean and the Food Dispensers are kept full.
If an Aquarium has two or more fish of the same species, and an Egg Cup, then a new fish of that species will periodically hatch as 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 species take a longer time to breed than others, so consider having an Aquarium specifically for that purpose.
Fish bred at the museum have the Select Specimen trait, which increases 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 the frequent Expeditions needed 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 have wall speakers mounted on the outside of them, allowing you to easily 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’re exceptional 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, since they donate based on Knowledge rather than Buzz, or use a DNA Designer to 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 your Food Dispensers, Filters, and Heaters within 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 room makes 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.
