Yes it is inhumane to keep any fish in a tank without a filter if you do not want to put the effort into changing the water frequently. Fish can be kept without if the water is changed regularly, but maintaining the correct water parpmeters is hard. As they will die if the water is not changed regularly a filter must be used if you don't want to put as much time and effort in. IT IS EASIER TO KEEP FISH IN A TANK WITH A FILTER THAN ONE WITHOUT

Goldfish do not necessarily need an air pump as they can breathe oxygen from the surface. Some fish that may benefit from an air pump in a 5-gallon tank are bettas, tetras, and dwarf gouramis, as these fish species prefer well-oxygenated water.


What fish do not need a pump for example the betta fish or Siamese fighter What about guppies?

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.

What does an aquarium pump do?

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.


What does an electric air pump do for aquariums?

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.


Can not having an air pump kill your aquarium fish?

if you have 1 or 2, then no. just dont put a tight cover on the cage because the fish use our oxygen from the top of the water to breathe. if you have a bunch of fish,you might need one. :) It is possible your fish will not survive without the pump. It depends on what you are using to induce air into the water. There are some varieties of fish that do not need a pump such as gold fish and bettas. Call your local Pet store for more information when in doubt. Most fish tank kits come with a pump included. Technically, the "air pump" is not necessary at all; oxygen does not get into the water from the bubbles. What the bubbles really do is cause the water to circulate, bringing water up from the bottom of the tank to the top of the tank where it can pick up oxygen from the air. Any other method of circulating the water in the tank would work just as well.
