uh, a few seconds on Google is all that you needed.

Betta's can be a very aggresive fish, especially the males. They may go after smaller slower moving fish that stray into their territory of the tank. If they stress out the fish enough that they kill it they will nibble on it, however Bettas are not a large carnivores and shouldn't be fed feeder fish. In fact, scince most feeders are goldfish (of a sort) the feeder may stress out the betta to the point that it will kill the betta. It is best just to feed a betta high protein flakes. Most pet stores that sell bettas also have food formulated for bettas scince it is such a popular species.

Roundfish is a class of fish including trout, bass, cod, pike, snapper and salmon. It is used for cooking.

All of the gases preserved in the soda escape and what's left is the syrup, coloring, and flavoring, making a sticky, gooey substance.

Tap water is public water that you get out of the tap of your kitchen sink. This term is used to distinguish from purified bottled water. tap water is water you get from the tap. In other words, it's not bottled.

i would say no. you would not know what kind of fry they may produce. also, it is quite impossible as both are very territorial and it is very difficult to differentiate between male and female for the oscar. so it's not worth trying it. i can say NO!

The letter shows that the Chinese feel that natural and political events are related. For example, Lin claimed that Queen Victoria could forestall heaven-sent calamities by calling a halt to the opium trade

No, not really. A small fish bowl will do just fine.

No, no and no! Siamese Fighting Fish are aggressive tropical fish, meaning they are best housed alone and NEED a tank consistently at 27.5*C. Goldfish are cold water fish and produce a lot of waste and can grow to 2 feet depending on variety. They need a large tank to stop them being burnt from ammonia buildup and to allow them to grow. A goldfish kept in a small tank will stop growing externally but not internally, resulting in an internal rupture and a long, painful death. All fish need filtered tanks that have been cycled to build up a bacterial colony.

that is algae get a fish tank scrapper and put a rubber glove on and clean it off otherwise it will keep growing

I think it depends on their gender.Two (or more) males can't be in the same tank,but a male and a female(s) can live in the same tank.And I've heard you can put neon tetras in the same tank but I'm not sure.

Yup, Goldfish eat practically anything which will fit into there mouths... weird

fish attract a mate with bright colors and large, flowing fins.

It depends how large the tadpole is. Bettas can not eat anything larger than their mouth.

Fishes are read for one of three reasons; food ornamental (aquariums) and sport fishing.

no but i did some research and u can have Aquatic Snails,Chinese Evergreen plants, and African Dwarf Frog

. hope u find this usefull

Female fish just lay eggs and without the fertilizer from the male the embryo in the eggs won't survive long enough to hatch. I'm not an expert, but I'm pretty sure that's how it goes.

male betta fish make a nest for the female on top of the water for the female to lay the eggs inside the nest. then the male will fertilize the nest, but the female has to have a nest to lay the eggs.

The best way to keep any fish healthy and give it a long life is to provide them with water parameters and conditions that suite their particular species requirements perfectly and also to provide a variety of nutritious foods (including live foods) that are suitable for the species. Absence of stress is another thing to keep in mind as stress is a well known killer of most life forms. Conditions required for a Beta splendens are a lit, covered, well planted, heated, filtered, tank containing a minimum quantity of 8 gallons of water. (NOT a 2 gal NOMINAL sized tank or a bowl). Optimum water parameters for Betta splendens are Temp 78F, pH 6.8 GH >150ppm. Water changes of 50% weekly are good. There are good commercial Betta specific foods available and these can be used as a basic diet that should be enhanced(varied) by the addition of various live foods such as Daphnia, Brine shrimp, Mosquito larvae, White worms and any other live food that is small enough for the Betta to swallow and is available at the better pet shops. Being a short lived species, given all these reasonable conditions a Betta can be expected to live around 4 years.

There is no such thing as a fighting fish that originated in Japan. However there is a fighting fish that evolved in tropical Asia and that is probably the fish you are refering to. Its' proper name is 'Betta splendens' and its expected life span under good conditions is around 3 to 4 years. When kept in the tiny containers some people insist on using to house them, they rarely live for much more than 2 years

I have a tank of all male Red Wagtail Platys, they don't fight besides a little chasing, but no nipped fins. Granted, they are still fairly young and i'm not sure about adults.. I would say they wouldn't fight though.

In the insect world they use a lot of pheromones in order to attract their opposite sex.

When you look closely on a butterfly, they do have some large antennas on their head. These antennas are used in addition to balance, also to get the scent of "things", hereby also the partner.

It is also thought that butterflies and other insects are sensitive of other wavelengths of light than what is visible to us humans.

Using special light-spectrum recording instruments we can capture different wavelengths reflected by these insects. Some look really quite amazing, and it is also thought that these patterns of "colors" not visible to man, play a role.

I would suggest a combination of both Pheromones and vivid colors not visible to the human eye. Pheromones for the long distance "phone call" (the male can sense the female pheromones from up to 2 kilometers away. Some moths can even sense their female as far away as 5 kilometers) and possibly colors when they are homed in.

Science is scarce regarding the aspect of different wave lengths of light. Science have started exploring this issue and this leads me to believe that many a book will in turn have to have added information to them in order to be 100% correct.

1997 was year of the ox. This year is the year of the tiger (2010).
