Fish

2-3 common goldfish can live quite comfortably in a 25gal tank for many years, though they'd be unlikely grow to full size there. It's possible to fit more in at the expense of water quality. Fancy goldfish will generally require more space especially if they live with more agile fish. Because this question is categorized under "goldfish", this doesn't apply to schooling fish which produce less waste and require less space than goldfish do.

it is double the size of a football field and it is a custom, oviasly

All fishes are adapted to live in water because they dont have lungs they have gills which means that lungs work with air and gills work with water. Have you ever thought does a fish dies when taken out of the water it is because gills are the only way a fish breathes through. Gills work when a current of water slide over them so when the fish is taken out of the water, the gills stop working because the current of water didnt slid over it.

about 30 to50 eggs

Philippine rivers, lakes and seas teem with fish, shells, pearls, corals, seaweeds and other forms of marine wealth. More than 2,000 species of fish are found in Philippine waters. Among the commercially known fish found in the numerous fishing grounds of the archipelago are the banak (mullet), bangus (milkfish), dalag (mudfish), dilis (anchovy), kandule (catfish), lapulapu (seabass), talakitok (pampano), tamban and tunsoy (sardines), tanguingi (mackerel), and bariles (tuna).

Small sturgeon eat very small organisms & larvae. As they mature they will eat almost anything such as: decaying matter/fish, mollusks, crustaceans, shrimp, crayfish, snails, clams, muscles, insects, worms, eggs of other fish mainly salmon, worms, some aquatic plants. Small fish such as herring, smelt, sunfish, bass, trout & shad, but also salmon. They like squid and are known to eat mice, rats, & frogs.

Mainly dead or alive stuff that is on the bottom but they will pursue live fish and may even feed on the carcass of other sturgeon.

Hatchery sturgeon are usually fed specially formulated sinking pellets, but also squid & trout.

yes but it depends on the type of sushi you are feeding it

I would guess around 5 or 6 per 10 gallons of aquarium space, but a lot depends on whether they are little tetras, medium gouramis, or large plecostomus catfish. The large fish pollute the water faster, so you must have less of them than you would of, say, the little zebra danios.

One physical factor that would affect fish population is the temperature of the water. Fish are generally very sensitive to changes in temperature, and if the water becomes too hot or too cold, it can cause the fish to die or their eggs to not hatch.

100 chichiliion dawg......... home boy

whereas we have lungs for ventillation, the fish use gills, on the side of their head, usually.

As they swim, water flows over the gills and oxygen diffuses from the water into their blood stream.

if you need more info, then search gills on google!

:D

Some fish, called egg scatters, put their eggs in different places in weeds or gravel. As the female is laying the eggs, the male chases her around and fertilizes the eggs. If you are lucky enough to see this process, you may be amazed because the fish don't pay attention to anything else, even food! Tetras and barbs are examples of egg scatters.

Substrate spawners, such as catfish or cichlids, put their eggs on plants, a piece of wood or the tank until they hatch.

A very interesting type of fish are the bubblenest builders. They actually build a nest for their eggs in bubbles that the male blows. The bubbles look like foam and are held together by saliva.

Finally, mouthbrooders keep their eggs in their mouths until after they hatch. Both the male and the female may carry the eggs, and the carrier does not eat very much until the eggs hatch.

I'd suggest that you read the book of Genesis. It will tell you how everything was created.

The same way apes evolved into humans, through mutation. Also, the same way new viruses and other forms of life are coming into existence today.

I found a program on Discovery explaining the difference between ray-fin fish and lobe-fin fish to be very educational. Lobe-fin fish are our earliest ancestors with the same basic skeleton as humans having distinct finger bones and limbs. Ray-fin fish have the same limb that current fish have such as catfish or goldfish. They remained on that evolutionary tree where we humans branched from lobe-fin fish.

Pescetarianism is a dietary choice, in which a person does not consume the flesh of land dwelling animals. In contrast to a vegetarian, a Pescetarian eats fish and seafood, it is similar to (and often contains) the Mediterranean diet. Pescetarianism is the chosen diet of some people for various reasons, most commonly cited are health benefits.

Bonito are predatory fish which are from the Scombridae family of fish. They live in groups and are medium sized. They are salt water fish and can be caught for food.

The bubbles are a bubble nest. Male bettas are the ones that take care of the kids in betta society. They blow the nest and that usually means he's happy or ready to reproduce. They also sometimes blow them when the composition of their water changes or their is a barometric change in air pressure. It doesn't always mean they are ready to be parents, though and sometimes perfectly healthy males won't blow them.

Tilapia are freshwater and are raised commercially in ponds.

You have to eat some bread which causes the bone to go into your stomach. You can also try to cough it up, but that does not really help. Also, ehen you eat the bread, do not chew it alot so that the bread would take up more space in your throat which causes the bone to go into the stomach with a bigger chance of it not staying in your stomach.

No. The Amazon rain forest contains only freshwater, which no species of starfish can live in.

Kois are able to live to be 100-200 years old. The oldest Koi ever recorded was named Hanokot. It lived to be about 226 years old and was kept in a natural pond in someones backyard in Japan. Hanoko was passed on down from generation to generation.

Answer

The Sturgeon which goes back to prehistoric days. We have them in Canada and they are a protected species. Fishing of Sturgeon is 'catch and release.'

Neon Tetra are very small if your thinking pet wise.

As per Guinness world of record smallest freshwater fish in the world is "sinarapan"

S.N. (Mistichthys luzonensis) located in taal lake, Phils.

The word most smallest fish is a Paedocypris fish it is 7.9mm long

The lateral line is a system of sense organs; neuromasts situated along/in the lateral line detect movement and vibration in water. The system is important in schooling and predatory behaviour, as well as in general for spatial awareness. It allows detection of movement outside of the range of vision, or in conditions that reduce visibility.

Blind fish will orientate towards movement in the same way as fish that are able to see, but disruption of the lateral line also disrupts the response to movement.

Bettas possess what is called a labyrinth organ, which means that they obtain their oxygen by breathing air at the surface (unlike most fish, who get it from the water). Bettas enjoy having somewhat deep tanks to explore and swim in, but they need to have surface access for oxygen.
