Behavior

Most Mollies are very calm and peaceful, though they can become aggressive when kept with too many fish at once. This is why it’s so important that you get an adequate size tank. They are social fish that thrive with their own kind.

Natural Habitat

Molly fish tend to flourish and thrive in freshwater streams, though they can also live in salt water without any issues. They tend to be found in coastal oceanic regions as well as swamps.

Caring for Molly Fish

1. Tank Setup

Most Molly fish will require an aquarium that is at least 30 gallons, though you may be able to get away with a 20-gallon tank. It is important to factor in the size of the fish. The fact is that some Mollies are larger than others. The bigger the fish, the larger the tank should be.

You will be able to use a bubbler without any issues, as these fish do not mind the air bubbles. In fact, this is probably the ideal setup for this particular species. There are also sponge filter configurations that you should consider.

It is also a good idea to have a good amount of sandy substrate in this fish’s tank. This will allow you to put in plants, which is important. You will need to provide them with caves, rocks and other things they can take shelter in. This is a crucial aspect of keeping your Molly happy and healthy over the long term.

You don’t need any special lighting for these fish, so your basic lighting setup will do just fine. You also won’t require a water or air pump. Mollies are accustomed to slow moving water, and the filter will take care of this.

2. Water Conditions

It is crucial that you keep the water in your Molly’s tank between 72 to 78 degrees. There shouldn’t be much fluctuation. Make sure that the water has a hardness of 20 to 30 KH and a pH of 6.7 to 8.5. These are the ideal living conditions for this particular fish.

While you can use semi-brackish water in your Molly’s tank, this will seriously limit your options for tank mates.

3. Tank Mate Options

There are plenty of different fish that you can keep with Mollies, so you are going to have lots of options. You will, however, want to stay away from putting any aggressive or big fish in with your Molly. This includes most Cichlids, though there are some exceptions. Snails and shrimp make nice tank mates for these fish.

4. Diet

Because Mollies are omnivores, you can give them just about anything to eat. They prefer algae and plants, though there are lots of other options. These fish need lots of vegetation on a regular basis. You can put everything from spinach to lettuce in their tank, and they will gobble it up.

Some people who keep Mollies even make their own food at home, which is something else to consider. There are plenty of frozen foods to choose from as well. Mollies like Bloodworms as well as brine shrimp. Keep in mind that they respond best to live food.
