One of the most important things to keep in mind when keeping mollies is that they need a filtered aquarium. A filter helps to keep the water clean and free of harmful bacteria and other pollutants. This is especially important for mollies, as they are susceptible to a variety of diseases.
There are a variety of different types of filters available on the market, so you can choose one that best suits the needs of your aquarium and mollies. Some of the most popular types of filters include:
* Sponge filters: These are the simplest and most affordable type of filter. They consist of a sponge that traps dirt and debris from the water. Sponge filters are easy to maintain and are a good choice for small aquariums.
* Power filters: These filters use a motor to draw water through a filter cartridge. Power filters are more powerful than sponge filters and can be used to clean larger aquariums.
* Canister filters: These filters use a pressurized canister to draw water through a filter cartridge. Canister filters are the most powerful type of filter and are a good choice for large aquariums.
In addition to a filter, you will also need to provide your mollies with a heater and a light. Mollies prefer water temperatures between 75 and 82 degrees Fahrenheit, and they need a light cycle of 12 hours of light and 12 hours of darkness.
By providing your mollies with a filtered aquarium, a heater, and a light, you can help them to thrive and live long, healthy lives.
