A fish is any aquatic vertebrate animal that is typically cold-blooded, covered with scales, and equipped with two sets of paired fins and several unpaired fins.

Do fish have personalities?
Some research out of the University of Exeter suggests that fish do have personalities behind those blank stares. Tom Houslay and his research team exposed guppies to scary stuff—a fake heron (rather aptly named Grim) and a fake cichlid, a predator fish (they called him Big Al, which I appreciate more than I can put into words). The team recorded the guppies’ responses over several exposures to those scares, and not only did individual fish react differently to the fright, but they did so in the same ways time after time. The researchers thus concluded that the fish have their own, limited sort of personalities—in spite of being raised in the exact same environment, they respond to stimuli in ways that vary from fish to fish.
What is the average life span of a betta fish?
== == Most of these fish can live for 2-3 years in fish bowl. Normally, bettas live two to five years depending on how they are cared for. Male bettas that live alone in large individual tanks and get daily exercise have lived six years or longer in laboratories. Typically, males purchased from a pet store are over four months old, at a point when their finnage becomes fullest and most attractive. Due to their shorter finnage, females available in pet stores are often only three to six months old. Betta fish actually live for 4+ years, eight years is not uncommon, in a 2+ gallon tank. In petstores males and females are actually an average of two years old; a female's finnage is alway short. 2-3 years in a bowl but 6-7 in a tank. 8 years is not uncommon, though. You may find it that your beta lives longer with different plants, and tanks. the original lifespan of a betta is 1-2 years. But with exellent care it may live up to 5 years.

How much does a 120 gallon aquarium weigh?
Full or empty? If empty, about 110 - 120 lb. If full, about 1045 lb. -- Just remember saltwater is less dense and therefore lighter than freshwater, so an aquarium filled with salt would weigh more. Also, you must take into consideration interior additives such as substrate, rocks and other solids, if you are trying to calculate the weight bearing of a floor or stand.
Asked in Fish
Are there any freshwater organisms that will eat fish waste?
Not really. You should have a few catfish in your tank, depending on the size of your tank. They will take care of any excess food that you feed. Have a good bio filter & an underwater filter to work best. You should also have a cleaner gadget that sucks out the water. Every so often you should stir up the bottom gravel until all the dirt & waste is floating is up out of the gravel (no need to take out your fish, leave them in), then use your suction cleaner, put the suction end in the bottom 3 inches of water, not in the gravel, to suck out the bottom dirty water down about 1/4 to 1/3 of your total water, no more than that or will shock the fish. Refill with room temperature water that has been left to set for about 12 hours before hand or just use a dechlorinator to get any chlorine out. When you let your new water set for awhile the chlorine gasses will escape out. This all you need to do to keep your tank clean. Do not overfeed your fish. More tanks get dirty by over feeding and that is not healthy for your fish. Also leave the algae that is growing on the sides of the glass on the back wall of the tank. Algae growing in a tank, shows a healthy tank and you want to leave some of that algae in. Purchase a Chinese Algae eater, hardier than most of the algae eaters to help keep down the growth naturally. To be more specific, there are bacteria that do indeed break down the waste, producing their own waste which may or may not be more beneficial to the ecology of the tank. Aquatic plants, on the other hand, will make use of the nutrients that fish waste releases. However, only in a heavily planted tank will they make enough of a difference to cut down on the need for vacuuming gravel and it takes more work (and much more expense) to keep a heavily planted tank than to simply vacuum the gravel on a regular basis.

What is a goldeneye fish?
The Golden Eye Grunt is a member of theHaemulidae or Grunt Family which are known in Mexico as "burros." In Mexican waters, the Golden Eye Grunt is found south of Magdalena Bay on the Pacific side of the Baja California peninsula, and as far north as Santa Rosalia along the Sea of Cortez Coast. On mainland Mexico, it is found from Guaymas to Guatemala. The Golden Eye Grunt grows to a length of just over one foot and is generally found around inshore rocky reefs in the first 100 feet of the water column. The Golden Eye Grunt is viewed as good table fare but is quite rare and also small, making preparation questionable since they are usually too small to fillet.
Do fish lay eggs from their mouth?
No, they come out of a small tube under their body close to the tail fin called the ovipositor. There are, however, some fish commonly called "mouth brooders" that will either scoop up the eggs into their mouths and keep them there until they hatch or will keep the fry (baby fish) in their mouths until they're large enough to stand a better chance of surviving.
Asked in Fish
Why is the fish egg is larger than the human egg?
An obvious reason is that the fertilised fish egg must survive and grow independent of the mother's nourishment, whereas human embryos grow within the womb and are nourished directly and continuously by the mother. The human egg therefore doesn't require a store of nutrients, whereas the fish egg must contain all the energy the growing fish embryo will require until it hatches.
How do fish sleep without eyelids?
Sleep is a state of rest for the body wherein functions not required for merely keeping the body alive are generally reduced to some degree. It's often difficult to determine the neurological states of nonhuman animals, so the answer to that question involves a little guesswork. In the case of fish, it can be presumed that sight functionality is dealt with similarly to the way we deal with being unable to shut off our hearing while sleeping: unremarkable input is generally ignored by the brain, but something that grabs attention will cause sudden alertness. For instance, the sound of the house creaking might not wake you up, but a sudden bang will. This is helpful for survival and in an aquatic environment where a predator might come from any direction and make little or no sound as you sleep, lacking eyelids so that such visual input would alert your brain to jump to readiness could be the difference between continued life and becoming a meal.
Asked in Fish
Name part of fish you don't eat?
The only part of a fish that is generally not eaten are the entrails (guts). Canned sardines are eaten with their heads, scales, fins and tails, many trout have scales that can be eaten. In many parts of the world, fish head soup is a common meal. Certain fish eggs (caviar) are also eaten. Many times it depends on the size, type and diet of the fish that determines what are or are not edible parts.

What pets can you keep inside?
Well the most common would be a cat or a dog however you can also have the following animals depending on if you can care for them and have the time for them: Types of fish; Types of birds (my Nan had a parrot); Gerbils, Rabbits, Hamsters, Snakes, Rats, Mice, Tortoise, Types of Spiders; Frogs (they sell tiny ones at our fish local shop but you would have to look up what types you coulod have); Lizards (my cousin has one). There is probably alot more but that is all i can think of right now. as long as you have a the animals suitable environment requirements and you check with a proffesional before getting a pet you should be fine. Hope that helped! :D

Is .5 ammonia bad for the water in your fish tank?
Any ammonia is BAD. Your filter is not working well enough. To keep thing safe you will need to be doing some extra water changes (maybe daily) until the filter is working efficiently. Ammonia should be kept at 0ppm at all time. It is toxic and leave permanent damage to the fish even if the fish survive it. Either your tank has not been cycled properly or the nitrogen cycle has crashed, or you have not cycled your tank at all. You need increase the partial water change to minimize the damage.

Do betta fish eggs float?
Asked in Fish
How does fish get into man made lakes?
Most man made lakes are created by damming streams or rivers where fish already exist. Therefore, there's no real transport method required. Occasionally, I'm sure eagles or osprey catch a fish in one body of water and lose it over another. Not exactly a regular occurrence but it could theoretically start a population.
