Python / PyCharm missing argument 'self'?

Question

I'm currently learning Python and I don't understand what is wrong with my code, but PyCharm keeps giving me the following error:

Traceback (most recent call last):
File "C:/Users/Sam/PycharmProjects/untitled1/app.py", line 5, in <module>
    fish1.bubbles()
TypeError: bubbles() missing 1 required positional argument: 'self'

Here is my code:

import random
from Fish import Fish

fish1 = Fish
fish1.bubbles()

fish1.name = input("enter the name of your fish: ")
fish1.coords = ("({0},{1})".format(random.randint(1, 100), random.randint(1, 100)))

print("The fish's name is {0}, and it is swimming at co-ordinates{1}".format(fish1.name, fish1.coords))

and here is my Fish.py file:

class Fish:

    def __init__(self, name, coords):
        self.name = name
        self.coords = coords

    def bubbles(self):
        print("{0} blew some bubbles".format(self))

Any help would be appreciated!

You have the error in Creating Instance Objects

In this section fish1 = Fish you didn't create the instance, but try to use it fish1.bubbles().

So try change fish1 = Fish to fish1 = Fish(name, coords).

name and coords required in your constructor.
