Most of them pump air into the tank so that the fish can breathe better. You should get one if you have a bamboo shrimp, I know from expirience.
The usefull thing an air pump can do is to drive a filter which is designed to remove the poisons that occur in every fish tank. Simply using it to blow bubbles is a waste.
The air pump in a fish tank gives the fishes oxygen without it the fish may die, unlike some fish they dont need air pumps, but i would ask a local pet store what types of fishes need air pumps and which ones dont just too be on the safe side:)
Probably with an aquarium pump.
They do
yes
You need to get a water pump and filter for the aquarium at a pet store.
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.
You should place it above the height of the waterline outside of the tank (unless you have a submersible)
A website by the name of Marinedepot offers a wide variety of aquarium pumps starting as low as $15.99 not to mention they offer free shipping on a large amount of their merchandise.
Most chillers (except drop ins) need water to be pumped throught them.
umm....well the water runs through a pump wich cleans the water as it goes through
There are a few different types of pump you can use. An ordinary bike pump, for standard manual inflation A bulb pump, which can have similar results as the bike pump An aquarium pump to achieve noticeable change in the size of your belly A foot pump, to save the struggle of holding the pump in the air as you inflate An air compressor, fast but expensive XD And an automatic air pump to relax and let the pump inflate away I'm sure there's more but these are the ones I can think of :)
The worlds largest aquarium is The Georgia Aquarium.
