Besides being able to see their prey and recognize their owners, fish also can see a range of colors, since they have color receptors in their eyes. Many species of fish can also see ultraviolet light, which humans can’t.
Can a fish scream?
People aren’t the only ones who raise their voices at each other; fish can shout, too. After catching some blacktail shiners—little minnows characterized by a big black splotch on their tail fin—fishery biologists placed them in tanks equipped with underwater speakers to see if noisy conditions affect communication.

Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
Do fishes get thirsty?

Fish-keepers sometimes see their pets ‘glass surfing’ – swimming repeatedly up and down the glass of the tank. This could be the aquatic equivalent of the pacing of a captive tiger that’s bored from a lack of stimulation. But the fish could also be stressed from an overcrowded or unfamiliar tank.
