What fish lives longest in a regular fish bowl with no filters?

Answer 1

This list is going to be absolutely massive. There are literally thousands of fish that people put in aquariums, so I will list some of the most common by family and a few characteristics.

Goldfish

This ageless aquarium favourite has now been bred to include black, white, red and patched varieties as well as the timeless rusty gold. Goldfish are coldwater fish, and can tolerate a wide range of pH, temperature and salinity, making them ideal for beginners and low-tech setups.

Livebearers

My personal favourites, the family Poecilidae includes guppies, Endler's livebearers, swordtails, platies and mollies (as well as less colourful wild species.) The female livebearer gives birth to up to a hundred fry every month, which are freeswimming from birth. They are easy to breed and I'm currently overrun with platy fry.

Guppies especially are very hardy and tolerant, and are favourites for children and beginners. Platies are also very tough and are prettier than guppies in my opinion. They are my favourite fish. Swordtails, mollies and endlers are touchier and require more complex setups.

Corydoras

This catfish family is a big favourite for keeping a large aquarium clean. They are active schooling catfish, very easy to breed. The albino variety in particular is very attractive. Pygmy varieties have been bred

Plecos

The plecostemus is HOT. That's the only way to put it. Most of these fish grow very big - around 30-40cm - but there are plenty of plecos suitable for large community aquariua. Plecos are catfish. The bristlenose catfish is a small pleco species.

Angelfish

Angels can be delicate, and are not good for beginners. They can also be aggressive, and will eat tetras. They are very attractive, and a good addition to a community aquarium that does not contain tetras if kept alone.

Tetras

These small, colourful fish are very attractive and very much favourites in a community aquarium. They are not very tough, and it's easy to kill them with a sudden shock like a temperature change or a pH jump.

Answer 2

Betta fish are the best. Goldfish second. Those would be the best. You can have 1 for each gallon. Unless you have a betta. Then you can only have one. Though I do have a small school of elder guppies in my bowl that have had for a year and a half. But make sure you have water conditioner and that when you get the fish you allow them to sit in the bowl in the bag from the fish store to make sure they have acclimated to the temprature of the bowl. Even what seams like a small difference in temp. to us can kill a fish within an hour.

Answer 3

Certain fish - such as goldfish, which are very hardy creatures - can survive in a fishbowl. However, life expectancy will be reduced, in some cases dramatically, as the shape of the bowl creates a surface area which is relatively small when compared to the volume of the water. This leads to water with far lower oxygen levels than is found in a conventional square or rectangular tank, either of which is a far better environment for fish.

Answer 4

A betta fish. They can live in fish bowls :) and they don't need filters or anything :)

hope I helped :)
