Yes! A filter uses live bacteria to biologically change the poisonous Ammonia that is created by fish breathing and pooing in their water, into relatively harmless Nitrate. It should be on permanently and allowed to run constantly. If you turn it off the good live bacteria will die and add to the poisons in the tank.

Do goldfish need filters?
Yes they do need a filter. People often think they can live with no filter in small bowls, this is not true. Goldfish are very dirty fish because people often overfeed them so make sure you have a filter. If you have a goldfish you have a Goldfish you should also have a tank at least 10 Gallons. If you have more than one fish with your goldfish or have lots of goldfish you need an aquarium larger than 10 Gallons so that all the fish have lots of room to swim. If your fish have no room to swim and have no filter they may be on there way to dying.

Is a small betta fish bowl good for goldfish?
A small fish bowl is bad for any fish. You need minimal 5 gallon for a single betta. You need minimal 20~30 gallon for a single fancy goldfish, 40~55 gallon for a single common goldfish. Because fish produce ammonia and it is toxic to themselves. Goldfish has such large body mass, so they produce enormous amount of ammonia. You must have a good filter system, and do a nitrogen cycle first before adding any fish at all.
