Yes, without a filter in their tank, your fish may die due to poor water quality and lack of oxygenation. Filters help remove waste and maintain a healthy environment for your fish to thrive.

Should you always keep a filter on in a fish tank?

Yes you do need a filter in your fish tank ifyou don't the tank will build up dirt and the fish will die. Also when you get a fish tank you need to clean it out then fill it with water then put the filter in and wait 24 hours. This helps to ensure that the tank is somewhat stable before adding fish.

Do coldwater fish need a pump in a small tank?

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

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.
