Betta fish can survive without an air pump or filter for a relatively extended period compared to other fish, thanks to their labyrinth organ. This unique adaptation allows them to breathe atmospheric air directly from the surface, in addition to obtaining oxygen through their gills.
However, while bettas can live in conditions without an air pump or filter, the quality of their environment will deteriorate over time without proper water circulation and filtration, leading to the buildup of harmful toxins like ammonia and nitrites.
The duration a betta can survive in such conditions depends on various factors, including tank size, water temperature, the presence of live plants, and maintenance routines like partial water changes.
In a small, unfiltered bowl, a betta may live for a few months to a couple of years, but this is far from ideal and can severely impact their health and lifespan.
In more optimally maintained conditions, with regular water changes and careful monitoring, bettas can live longer, healthier lives, even without mechanical filtration or aeration.
To ensure the well-being of a betta fish, it’s essential to maintain clean water conditions through regular water changes and to provide an environment that mimics their natural habitat as closely as possible.
This includes warm water (between 76 to 82°F), hiding spots, and possibly live plants that can help oxygenate the water and absorb some of the toxins.
While bettas can technically survive without an air pump or filter, their quality of life and health are significantly improved with proper care and a suitable living environment.
Now you have an idea of how long betta fish can survive without an air filter, but do you know how long can betta fish live without food? If you don’t know then follow our previous article.
