The aquarium in "Double Point Museum" can breed fish, but this requires you to unlock the egg cup first, which can be added to any aquarium. Egg cups are large and expensive, and cost $15,000, but they allow you to breed fish in the aquarium and expand your fish collection without having to let employees on dangerous adventures.
How to breed fish in the Double Point Museum Aquarium
In the third chapter of the plot of "Museum of Marine Life", you will unlock the egg cup, which can be added to any aquarium. Egg cups are large and expensive, and cost $15,000, but they allow you to breed fish in the aquarium and expand your fish collection without having to let employees on dangerous adventures.
Fish will only breed when healthy, so make sure the aquarium is kept clean and that the food in the feeder is always adequate.
If there are two or more fish of the same species in the aquarium and one egg cup, new fish of that species will be hatched regularly as long as there is free space in the aquarium. If there are multiple species in the same aquarium and all breeding pairs, they all have a chance to reproduce.
Rare and large species have longer reproduction times than other species, so consider setting up a special aquarium for this purpose.
Fish breeding in museums have the "selected sample" characteristic, which will increase their sales value by 10%. Once you have fully analyzed each species in your collection, keeping free space in the aquarium to breed and sell new fish is a great way to increase museum revenue!
