Aquarium Conditions

In the wild, clownfish living in coral reefs will go into a swimming reef and stay near it unless they are sick or injured.

Clownfish will also thrive in a well-oxygenated aquarium with a moderate level of hardness.

Water Filtration

There are a few different types of water filtration systems that can be used with clownfish, but the three most common are mechanical, biological, and chemical. Mechanical filters use spinning disks or pads to remove particles from the water. Biological filters use bacteria to break down pollutants. Chemical filters use chemicals to remove particles from the water.

The best water filtration system for clownfish depends on the type of aquarium they will be living in and the type of fish that will be living with them. In general, mechanical filters are best for small tanks with low levels of pollutants, while biological filters are best for larger tanks with high levels of pollutants. Chemical filters are generally not necessary for most aquariums, but they can be helpful for those with a discus or angelfish tank.
