manage to live in a fishbowl without a filter, oxygen, or air pump.

I believe that I have proven that tropical fish, can be kept in small bowls, without a filter or airpump. And these fish will be happy. (But perhaps? to keep tropical fish in a bowl so small, you may need plants, a ghost shrimp, and some snails, to make it a good eco-system for tropical fish.

Fishbowl filter kit fits all drum/round bowls with a 4in or larger opening. Fishbowl pump and filter kit include under gravel filt

Goldfish need plenty of oxygen and an aquarium air pump is highly recommended as it helps reduce stress too. As we all know with stress can come sickness and diseases so it is always best to take all necessary steps to keeping goldfish healthy. I mentioned about a goldfish pond in the summer just to explain a little more on this subject. As far as goldfish bowls and aquariums are concerned it is to your best option to go and equip your fish tank with an air pump. The agitation that happens at the surface of the water will add oxygen to your fish tank. This will create a healthier home for your fish and will reduce stress. If people are planning on having good luck taking care of goldfish then I would suggest not to go and try and keep them in a goldfish bowl. It’s just too small and in order to have great luck with fish keeping I would get all the proper equipment needed such as air pump, filter and aquarium gravel. With basically everything in life things need oxygen to live and goldfish are much the same. Also beneficial bacteria in your filter need oxygen to live and reproduce. Air pumps can help in so many ways in keeping an aquarium healthy. I hope this helps give you more of an idea on why people should really have an air pump in their fish tank. Your goldfish will like you for it and you will have better luck with your overall experience in fish keeping. Having an air pump in your goldfish aquarium is absolutely necessary towards optimum fish health.

Aquarium filters scale up in size based on how big your fish tank is

Well, after browsing around here I feel like I must add my story... Adopted my Mom's Comet fish Nana, when Nana was 3ish. She lived happily in a small 2ish gallon, decorative bowl with silk plant and 1/2 - 3/4" round stones... No filter, no air pump, just water changes. She continued to live happily 5 more years with us on our kitchen island, with one upsize to a bigger 3ish+ gallon bowl, silk plant and more 1/2-3/4" stones. Her demise happened 4 days after my girlfriend (who rarely preps any food), hammered 4lbs. of chicken (on a Monday night) with a heavy saucepan on the island Nana lived on, (I was so mad at her for stressing Nana out like that, "Are you trying to kill Nana fish?!...WTH!? Lisa!!" Sure enough Nana went downhill pretty fast after the hammering incident. The night she was obviously dying and did die, I noticed about 3-4 days worth of fish food on the bottom (never, ever, have seen uneaten flakes like that before). I'm no expert or fish whisperer, but Nana was her active, happy self on Sunday and dead on Friday... After what I believe we're 8 active, happy years... She maybe grew an inch in the 5 years we had her (to about 3ish inches - tip of nose to tip of tail)... I never did any research on goldfish (until now, cause she is gone). I just did what I thought was right to keep her alive, well and what I believe as happy... Coincident with hammering incident, maybe... I do believe that played a part in her passing... I am sad :( RIP Nana Fish...
