While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
Does fish do potty?
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.

A lot of fish get rid of the pee through an tiny opening, called a pore, that’s near their rear ends—and in some fish, waste also goes out through the skin or the gills. When a fish pees in a coral reef, the corals wave their tentacles around like tiny arms to grab nutrients from the pee and absorb them.

Can fishes feel pain?
A significant body of scientific evidence suggests that yes, fish can feel pain. Their complex nervous systems, as well as how they behave when injured, challenge long-held beliefs that fish can be treated without any real regard for their welfare.

Can fish see in dark?
Fish living in the deep sea manage to navigate in complete darkness. It’s not strictly ‘seeing’ but fish have rows of pressure-sensitive organs running down each side of their body called the lateral line, which allows them to sense nearby animals from the pressure changes in the water.
