Fish are aquatic animals who live in diverse habitats.

In the wild, fish are threatened by habitat destruction, overfishing, pollution and climate change. Some species of fish, highly sought after in the aquarium trade, are taken from the wild and traded internationally. Fishers may use harmful practices such as spraying cyanide in the water to stun and catch fish. Once in captivity, fish may suffer due to their owner’s lack of knowledge on proper tank size, diet and tank mates. Some species of fish, such as salmon, are often farmed for human consumption.

Fish are largely believed to be unintelligent and incapable of pain, but scientific evidence suggests otherwise; fish are able to recognize other fish, establish social hierarchies and remember their surroundings.
