Yes, but if he is nesting, it needs to be turned very low so as to avoid damaging his bubble nest.
no a water pump can not kill a fish
No they breathe from the top of the water like a porpoise
Betta fish do not need to be in oxygenated water because they gulp air from the surface of the water. They can be kept in a variety of small containers. I found some really stylish ones online at www.bigalsonline.com. I attached a link for you!
You could put the following: 3x Neon Tetra or... 1x Betta
An electric air pump oxygenates the water in an aquarium, this allows the fish in the fish tank to breath. if there was no air pump the water would lose its oxygen and the fish would drown.
To clean the pump or motor of your fish tank, just rinse with water. If you use chemicals or soaps it will most likely kill the fish or damage it tremendously. just rinse it well with water and you will have a nice and clean pump for your fish tank.
One Gallon? Only a Betta. Most anything that's small enough for a 1g is to active for one. A micro-tank can be absolutely lovely though if you plant it really well, get a rams head snail to keep waste down, and pick out a really pretty Betta.
A betta, is fish that lives alone in the wild, and likes it that way, your betta is doing what comes naturally to it, if you want to enjoy your betta get a clear bowl or vase, any size will do, put some gravel in it with some live plants an your betta will be very happy, bettas breathe air like we do, so you don't need an air pump,and you only have to change the water when you do not like looking at the alage or dirt on the stones or glass, the betta does not care how dirty or how much alage is on the glass.
I don't know what beta fish are but I can assure you something. All fishes need a pump for a healthier living. Only one Siamese fighter can be put in a tank. It is better to use a bowl for this. Water should be changed every 2 weeks. If these conditions are satisfied the fish will be fine. I am a successful breeder of guppies. As far as I know It is is advised to have green plants rather than a pump in their tanks.
I would be inclined to suggest you turn the air pump off. Bettas do not like or need that kind of disturbance (heaps of rising bubbles) in their tank and it will certainly be doing the fish no good. If you drive a filter with your air pump you will be doing something positive that will benefit the fish. Any food left in the tank must be syphoned out immediately after the 15 minutes you should allow for the fish to eat what you give it. Failure to do this will eventually result in poisoned water and dead fish.
Well with a male NOTHING! Well it depends on what the attitude of the male betta fish is. To be safe though do not put anthing with a male. As for a female you can put a lot of fish. Here are just a few, Guppie, another female betta (up to 3)(not male) there are a lot of others I just can't think of them right now sorry!
Sounds good, okay, if you get a MALE betta, (bigger with longer fins) then you can only have one, one betta that is, the ONLY other kinds of fish that can live with a MALE betta are neon tetras and other very small peaceful fish, no barbs or danios eather, they are fin bitters are there.. twitchey swimming annoys the peaceful better, al so called the Siamese fighting fish, because the males will kill nearly anything in there path, even a female if it is not mating time, but the female bettas, are a little smaller with much sorter fins, are very good little fish, i have 5 in a 40 gallon tank with rainbow sharks, neon tetras, gouramis, 1 gold fish, and alot more. but in a 10 gallon tank, you could have ether 1 male, and up to 5 neon tetras. OR, up to 4 FEMALES, and up to 3 neon tetras, never get less than 3 neons though, they are schooling fish, its quite adorable :D also, there is another kind of fish, called a cardinal tetra, they are just a bigger version of a neon tetra, they are okay too, just take the larger size into account, and use common sense, good luck =D
