Another benefit of having guppies in a tank with mollies is their ease of care. Both fish are hardy and adaptable, making them suitable for beginners. They eat similar foods, so feeding them is simple. With the right conditions, these two types of fish will thrive together, creating a peaceful and lively tank.
Corydoras Catfish: Peaceful Bottom Dwellers
Corydoras catfish are peaceful bottom-dwellers that are a great addition to tanks with mollies. They are known for their calm nature and ability to help keep the substrate clean by scavenging leftover food.
These fish are social, so they prefer to be kept in groups. They are also adaptable to different water conditions, just like mollies. As long as the water parameters are stable, both species can thrive together. Corydoras are peaceful and rarely engage in aggressive behavior, which makes them ideal companions for mollies. Their slow-moving nature ensures they don’t disturb the mollies, making for a peaceful tank environment.
Adding Corydoras to a tank can help improve its overall health. As they scavenge, they assist in maintaining a clean and balanced ecosystem.

FAQ
Can mollies live with other livebearers?
Yes, mollies can live with other livebearers such as platies, swordtails, and guppies. These species share similar care requirements, including water temperature, pH levels, and temperament. Since they are all peaceful and non-aggressive, they can coexist without issues in the same tank. It’s essential to monitor their behavior and make sure the tank is large enough to accommodate everyone comfortably. Overcrowding can lead to stress and aggression, so ensure there’s enough space for all the fish to swim and explore.
What size tank do mollies need?
Mollies are active fish and require a tank that provides them with enough swimming space. A 20-gallon tank is the minimum recommended size for a small group of mollies. Larger tanks are always better for multiple fish or if you want to add other species. A larger tank helps maintain stable water quality and ensures that the fish don’t feel cramped, which can reduce stress. If you plan to have more tankmates along with mollies, consider a tank of at least 30 gallons to ensure a balanced environment.
Are mollies aggressive towards other fish?
Mollies are generally peaceful and not aggressive. However, they can sometimes display territorial behavior, especially when they feel crowded or stressed. This behavior is more common in males, who may become more territorial when competing for mates. If you’re concerned about aggression, you can balance the number of males and females in the tank to reduce conflicts. Providing hiding spots and plants will help mollies and their tankmates feel safe. Overall, mollies are a calm species that can coexist peacefully with a variety of fish if properly managed.
Do mollies need a filter?
Yes, mollies benefit from a filter in their tank. Like all fish, mollies produce waste, and a filter helps keep the water clean and free from harmful toxins. A good filtration system ensures the water remains clear, maintains oxygen levels, and helps stabilize the tank’s environment. It’s essential to choose a filter appropriate for the size of the tank to prevent water quality issues. Regular water changes (about 25% weekly) are also necessary, even with a filter, to maintain a healthy environment for your mollies and other tankmates.
How many mollies can live in a 20-gallon tank?
A 20-gallon tank can comfortably house around 4 to 6 mollies, depending on their size and whether you have other species in the tank. Mollies are social fish and prefer being in groups, so it’s essential to provide them with enough companions to feel secure. However, overcrowding should be avoided as it can lead to stress and poor water quality. Make sure there’s adequate space for swimming, and keep in mind that a larger tank is always better for maintaining a balanced environment.
What do mollies eat?
Mollies are omnivores and enjoy a varied diet. Their diet can consist of high-quality flake food, pellets, and frozen or live foods such as brine shrimp, daphnia, and bloodworms. They will also graze on algae and plant matter in the tank. Mollies should be fed two to three times a day, but you should avoid overfeeding. Leftover food can quickly deteriorate water quality. A balanced diet is important for their health, so offering a mix of protein, vegetable matter, and algae-based foods will ensure they stay healthy and active.
Can mollies live in freshwater?
Yes, mollies are typically freshwater fish, but they can tolerate slightly brackish water conditions. While they primarily live in freshwater, mollies can adapt to water with a small amount of salt, which can help with their overall health and immune system. If you decide to keep mollies in brackish water, it’s essential to monitor the salinity closely, as too much salt can stress them out. Generally, they are most comfortable in freshwater with a slightly alkaline pH and a temperature range of 72-82°F.
Do mollies breed easily?
Yes, mollies are livebearers, meaning they give birth to live young instead of laying eggs. They breed relatively easily in the right conditions, and it’s common for them to have several batches of fry each year. To encourage breeding, provide a well-maintained tank with stable water conditions, plenty of hiding spots for the fry, and a mix of males and females. If you don’t want the mollies to breed, consider having an all-male tank or separate the males and females. Additionally, if fry are born, you can separate them from the adults to prevent them from being eaten.
How long do mollies live?
Mollies typically live for 3 to 5 years, although some can live even longer with proper care. Their lifespan depends on factors such as water quality, diet, tank conditions, and genetic health. Regular water changes, appropriate feeding, and maintaining a stable environment will help mollies live longer, healthier lives. Providing them with tankmates that share similar needs can also reduce stress and contribute to their overall well-being. With proper care, mollies can be a colorful and lasting addition to your aquarium for several years.
Are mollies hardy fish?
Mollies are generally considered hardy fish, but they do require stable water conditions to thrive. They can adapt to various environments, but they still need a clean, well-maintained tank. While they are not as delicate as some other species, mollies are sensitive to sudden changes in water temperature, pH, or ammonia levels. Regular water tests and maintenance are essential to keep them in good health. With proper care, mollies are durable and can thrive in a variety of tank setups.
