There are a number of fish that don’t need a filter and heater in their tank. These fish are typically those that come from habitats where there is little to no water movement and the water temperature is stable.

Can You Keep Fish Without a Filter?

In short, yes you can keep fish without a filter, however there are some things to consider before making this choice. The most important factor is the size of your tank. A small tank is more likely to experience water quality issues without a filter than a large tank.

This is because the larger the tank, the more stable the water conditions will be. Ammonia and nitrite levels can rise quickly in a small un-filtered tank, leading to fish stress and illness. A second factor to consider is the type of fish you keep.

Some fish are much more sensitive to water quality than others and will not do well in an un-filtered aquarium. Goldfish, for example, are very hardy and can tolerate poor water conditions better than most other fish species. Finally, you must be willing to perform regular maintenance on your un-filtered aquarium including frequent water changes (at least weekly) and vacuuming of the gravel bed.

An un-filtered aquarium requires more work than a filtered one but it can be done successfully with some planning and effort.
