Climbing perch, or walking fish, member of the labyrinth fish family, adapted to living in oxygen-depleted water or on dry land. Members of some species can remain out of water for several days and will even suffocate (drown) if held underwater.
It can live on dry land
A perch is a fish. Fish are not mammals. They don't have fur. They don't give birth to live young and feed them with milk. They are not warm blooded. Fish are fish.
There are different types of fish that live in the Niger river. They include Nile Perch, catfish, salmon, minnow, and herrings.
There are many different kinds of perch. If you mean the perch that coarse fisherman catch in England, a predatory fish with a green striped body and red fins, then this is widely distributed through most waterways in the British Isles. There are also tropical perch species, that aren't related, such as the Ctenopoma or bush fish that live in Africa. And then there are many sea fish that are known as perch, that again aren't related, and which live all over the world.
No, perch are not typically classified as scavenger fish. They are primarily predatory fish that feed on smaller fish, invertebrates, and aquatic insects. While they may opportunistically consume dead or decaying matter if it's available, their diet mainly consists of live prey.
Yellow perch hunt insects and smaller fish in murky water. They are capable predators and derive most of their nutrients from hunting live prey.
The Climbing Perch or Climbing Gourami has the same dietary needs as the other members of its family. They are all basically insectivores/carnivores, and eat whatever insect larvae and other small creatures they can find. Things like mosquito larvae, daphnia, baby or small fish all make a good snack for them. Special Betta food is a suitable basic diet which should be suplemented with a feed of live food (brine shrimp etc ?)when possible.
No, perch do not blink, humans have to blink to give mosture (a little bit of water) to thier eyes, but perch practicly live in mosture, so therefore they do not need to blink so they dont, that is the same with all fish.
On land
Goldfish will die within minutes of being out of water but Bettas are slightly different. Bettas have a labyrinth organ that allows them to breath air as well as using gills. In theory they could survive much longer out of water than most fish but will eventually die due to drying out. Some other members of the labyrinth family like the Climbing Perch are capable of surviving on dry land for days.
amphibious fish
Yellow perch hunt insects and smaller fish in murky water. They are capable predators and derive most of their nutrients from hunting live prey.
