We often wonder whether there is any kind of fish that can survive in a low maintenance setup without the provision of artificial oxygen to keep them going. Figuring out the answer to this is always accompanied by a desire to get a fishbowl at once – and fill it up with such kinds of fishes! After all, who does not like to stare at a fishbowl for hours, noticing the little movements and activities of the fish in their exquisite environments?
To begin with the list of fish that can live without oxygen it is an axiomatic fact that most fishes require the aid of oxygen in the aquarium because they are delicate animals, and proper care is an essential factor in their upbringing. But if you are instead choosing to keep some fish in a fishbowl, you can do so as well. It gives a sophisticated look to the aquarium and simultaneously cuts your budget down!
How can they survive without oxygen?
The guppies are one of the first fish that comes to mind when one talks of fish that can survive without oxygen. Coming in various colours, with black or yellow stripes, guppies usually survive in huge numbers, so to avoid that, you can get guppies of the same sex to avoid their breeding. They are fascinating to look at and can easily survive for more than a few weeks without the aid of oxygen.
The paradise fish is another variety that one may opt for. Still, it is necessary to note that paradise fishes are pretty aggressive when it comes to co-existing with other kinds of fish, so it is wise to keep them alone. In addition, they are slow-moving and a bit larger in size than the guppies, preferring a tranquil environment. They can also survive for weeks without any source of oxygen.
The goldfish is, of course, one of the most popular types of fish – found in the aquarium of most households for the brilliantly vibrant and attractive colour. They are lovely to look at and are surprisingly low maintenance. If you want to keep goldfish in your fishbowl, all you have to do is change the water every two weeks, and they can survive easily. Again, to avoid the problem of breeding, it is recommended that you go for same-sex goldfishes instead of keeping them in pairs because that could lead to undesirable results.
In conclusion, if you want to have a truly low maintenance option of keeping fish, you could go for one of these varieties and watch your fish frolic for hours on end!
