Its 225gl. More of a rectangular shape. 6ftish long, would need to measure the width and height again but roughly 3ft and 4ft.
Thats as heavy of a load of fish I have had.
Pros- the fish are less territorial b/c they have have to "share" the space and not "own" a space.
Cons- lots of waste, predator fish carp a lot so have to stay on top of water chemistry.
I would start slow on adding fish, make sure you have the nitrogen cycle down, ect. I started with goldfish to get the bacteria going.
It's really trial and error. Some fish will do well in captivity and others won't. But you have 360gl to work with, have fun with it!
Don't worry about the mule, just load the cart
