Do all fishes pee?

Yes they do! But why? Well, like most living things, fish too produce waste from their metabolic processes. Peeing is one way of doing that and is referred to as excretion.
Do Fish Poop and Pee? Yes, fish do poop and pee as part of their normal physiological cycle. They excrete the waste generated in their body in the form of urine and faeces. Also, this is not an exception for some species but is a mandatory living cycle in just about every fish species you come across.
How do fish pee or poop?
So, how do fish expel their feces? Well most of them will expel their feces through an anal vent (also called a cloaca), which is simply an opening for all wastes to leave the body. This includes not only feces but also urine, reproduction, and sometimes eggs or sperm if needed.
A urinary bladder is present in fish as an expansible part of the urinary duct, in amphibians and bladder-possessing reptiles (Sphenodon, turtles, most lizards) as a pocket in the cloaca. In mammals it is a greatly expandible muscular sac.

Biochemist Stuart Jones explains that a person generally excretes 0.2L – 0.5L of urine at a time. This equals about three grams of urea. Even in if all the world’s 7 billion people peed in the Atlantic Ocean at the same time, there would be a minuscule amount of urea, Popular Science estimates.
Can men poop without peeing?
