Fish

Most fish hide from fear of being eaten. Fish have a cannibalistic nature. It is a known fact a small fish will be eaten by a larger fish. Some will even eat the eggs. If you will take notice, todays fishermen use a false bate to catch fish. These false batesoftenlook like a fish. As lovely as the lakes. ponds,rivers, streams and oceans may look, it is a very hard place for fish to live. It is like living in a war zone. They never know when theirnext swim willbe their last. Often, when a fish is looking for food, a larger fish is looking for food. The smaller fish is a meal for the larger fish. National Geographs has shown several shows about the life of a fish. For people, life can be hard, but be glad we are not like the fish. Atleast we have some protection by law. The law of the fish seems to be.... EAT OR BE EATEN!

Fish need a counter-current system in their gills to maximize the efficiency of oxygen exchange. This system allows blood and water to flow in opposite directions, maintaining a gradient that ensures oxygen diffuses from the water into the blood throughout the entire gill surface. As a result, fish can extract a higher percentage of oxygen from the water, which is crucial for their survival in often oxygen-poor aquatic environments. This adaptation enhances their respiratory efficiency, supporting their metabolic needs.

As a rule, they don't; however, some species have vestigal legs or bones that can be hidden within their bodies(ie: part of their skeletal system), while others like the Mudskipper have actual modified fins, etc. that work as functional legs and such which they use to make their way over land to get to new sources of water, among other things.

Both are usually coldblooded, usually egg-laying, live in water, normally smooth skinned (slippery) and most of them have gills, amphibians can be on land and water at the same time such as frogs.

All fish are vertabrates.

This will depend on what type of fish you purchased.

Most fish are egg bearing and unless there is a male to fertilize the eggs, then the female will either re-absorb the eggs, or release unfertilized eggs that will be eaten (such as a goldfish).
If you purchased a molly or a guppy for example, those are live bearing fish and it's not uncommon to buy a female that is already pregnant.

Jawless fish are cartilaginous, but they do not have jaws. Class Chondrichthyes, which contains most cartilaginous fish, like sharks, have powerful jaws.

Acanthaster planci

The term "green around the gills" is an idiomatic expression used to describe someone who looks ill, unwell, or nauseous. It suggests a pallor or sickly appearance, often associated with feeling queasy or about to vomit. The phrase likely originates from the idea that a person who is feeling nauseous might have a slightly greenish hue to their skin, particularly around the face.

The swim bladder can fill by gulping air at the surface, this enables the fish to float or empty by loosing air from the swim bladder through a pneumatic duct (a pneumatic duct is an internal gas filled organ) connected to the oesophagus, this enables the fish to sink.

Black spots on a fishes body is a symptom of black spot disease( a disease caused by a digenetic fluke. It will usually go away on its own, as the complex life cycle of the fluke can not be completed in an aquarium.

Fishes are generally cold blooded except some species.

It is only a two chambered heart, so it is not very efficient compared to us, but it does them good. That means there is only artery and one vein connected to it, it really just looks like a red clump of blood to the naked eye.
