Fish

because of there ancestors funny name but fish are descended from yes you guessed fisholatos they had blubber plus god gave them blubber so let it be(:

This largely depends on how well you condition the bettas before spawning, especially the female. If you try to spawn too early or do not feed her enough (in the two weeks before spawning, if she is eating everything you are offering you are not overfeeding) you will not get many eggs, maybe fifty or so. A well conditioned, fully grown female paired with an experienced male who looks after the eggs well may give you three hundred fry. A normal, well conditioned pair often lay 150 or so. Obviously it is silly to raise this many; it is best to wait until a week or so, cull everything obviously deformed or not growing, and then wait until six weeks and keep only the best to grow on. Not all of the eggs will survive. A good father will eat any egg that stops developing and becomes fungused, to protect the other eggs. However sometimes an inexperienced or confused male will spontaneously decide to eat the eggs or fry. If you can't afford to lose the spawn it is often wiser to remove the bubblenest, put it in a shallow container and float it in a heated tank. However, this does result in a lower hatch rate (50-60% as opposed to 80%.)

Any large fish can be dangerous to humans.

Smelt and alewife are both kin to herring.

If the fish name is a proper noun it is capitalized; but do not capitalize nouns such as black beta, angelfish, goldfish. The genus is capitalized, the species is not; both are italicised.

Cause they have bright colors and that looks cool . And how they bond with there anemones to share food.

Fish do not go through metamorphosis,(changing completely, for example caterpillar - butterfly). so it's simple, eggs, then very small fish, then it keeps getting larger so to make a long answer short - eggs, then fish

There is a great fish like that that eats coral, but extremely hard to get. YOu may want to see pro shops if you want one of those.

Tuna get oxygen through ram ventilation, which means that they swim rapidly in order to have water/oxygen move across their gills. If they stop swimming, they will suffoctate. Therefore, they need to swim even while they are sleeping!

Depends on what you mean. Fish skin is often slimy, and doesn't have to mean anything for the quality of the meat.

If the meat itself is slimy, but more importantly smelly, don't eat it.

I don't beleieve there is any single animal that gives "milk, meat and eggs" . -If I have misunderstood you, then possibly you need to learn better English.

There are 810 different types of Cartilaginous fish. Sharks have a lateral line system which detect movement in the water. Some sharks move even when they sleep so they could get water constantly through their gills. Some sharks lay eggs while others give live birth. The largest cartilaginous fish is the Whale Shark its about 30 feet long and weight up to 10tons.

Cats, birds, dogs, bears, predatory fish, otters, snakes, frogs, turtles, raccoons, etc. Basically if it can get into a pond that is contained and stocked with fish and has a taste for fish, a pond is a buffet.

No, it is not.

I can see how you might get confused because when you catch tuna you will probably catch dolphin. They also might slightly look like each other, but like the other person answered they are not. Dolphin is just a Dolphin. Other people call it Mai Mai. Dolphin and tuna are not related.

A starfish and a scale worm have a commensal relationship (commensal is a type of symbiotic relationship where the host benefits the stowaway but doesn't harm the host):

The sea star provides protection and food for the scale worm. The scale worm doesn't harm the sea star, therefore it is a commensal relationship.

Fish contain good minerals and provide a good source of growth for plantations.

Semicossyphus pulcher. The 1 you saw before (Archosargus probatacepalus, or somthing like that) was the scientific name for the Sheepshead Fish!

Its probably sleeping.

How can gold fish breed how long does it take what can we do to help them

I believe that that would be the Piranha.
The answer is piranha.

Rainbow fish (Melanotaenia sp.) evolved in and are lovers of, the clean, gently flowing, warm (70F), creeks and rivers of Tropical Australia and New Guinea. If their tank water is not up to their requirements or if they are overcrowded they may well not feed, and sulk until they die. 1" of fish needs 1 gallon of water. A cycled filter is essential. 50% of their water changed weekly is also a good idea for most fish including Rainbows. My advice is for you to do a large water change.

frogs have many things such as bilateral symmetry a mouth and an anus they are cold blooded creatures

fish are vertebrates. Their (bone) skeletons give their bodies structure.

Jellyfish live in bodies of water and like to eat smaller sea animals, such as crustaceans and mollusks. They are able to sting their prey, but are still a food source to some birds and turtles.
