A teaspoon of salt per five-gallon of water can help them with some problems. The balloon trait is obtained by selectively breeding fish who develop scoliosis (spinated spine). Balloon Mollies often have a reduced lifespan because of the inefficiency of the body shape, low-quality offspring, and possible genetic problems.
Balloon Molly Fish Lifespan
We can extend the lifespan of our fish by organizing and improving their environment, making maintenance and water changes regularly, keeping the water parameters optimal for the species, and offering high-quality food. It’s easier to avoid diseases than treat them. Therefore, everything mentioned above contributes to maintaining the fish’s immune system, reducing occurrences. So if you buy a new fish or plant, place it in a quarantine tank first, then release it in the main aquarium for some days. If you want to introduce newly acquired fish in your aquarium, quarantine them for up to two weeks.
Doing water changes for Balloon Mollies
Perform weekly water changes in your aquarium, changing at least 30% of the total tank volume. By changing the water, we remove pollutants and toxins that the plants and bacterias will not cycle. When you use tap water, treat it with a water conditioner. Tap water has chlorine, chloramine, and other substances that can be harmful to the aquarium and fish, so you must treat it. In each maintenance, the substrate must be cleaned perfectly, vacuumed, siphoning all the dirt; the aquarist must pay special attention to decorations and spaces where dirt can be trapped.

Do balloon mollies need live plans?

This plant does not require intense light and the addition of a CO2 system. Sometimes you may want to help them with liquid fertilizers.
