I believe the word you're looking for is "aquarium"

I laughed more than I should xD

At first before reading the title my mind went wild and I was like, "What kind of sick place melts animals and puts them in containers to show around!?" Then I read the title and was like, "Oh, aquariums. Much more sense."

what if it's like a museum displaying different water and drinks and liquids from around the world? then it would be a liquid zoo.

Liquor store. That's what you're thinking of.

haha
