Mollies bring a splash of vibrant activity to any aquarium, but their curious nature can disrupt the peace if placed with slow-moving companions.

Their occasional nibbling habits make them less than ideal tank mates for long-finned fish that need to keep up with their active lifestyle.

Mollies are active fish that love exploring their environment and feeding on whatever they can find.

The most common swimming pattern is steady cruising around the tank as they inspect every corner of their habitat.

It is often accompanied by fanning behavior in which they spread out their fins to collect food particles floating in the current.

Where Do Mollies Swim in the Tank?

Mollies prefer the higher waters, rarely straying far from their aquascape’s middle and upper fish tank areas. 

Keeping them out of deeper seas ensures these little swimmers remain safe and sound inside your tank!

In an ideal tank, mollies swim around the perimeter of the aquarium, paying particular attention to hiding spots and any live plants or other decorations they can use for shelter from strong currents.

They prefer well-oxygenated water (pH levels between 7.5 to 8.5) with plenty of space to explore and forage for food.

7 Sick Fish Signs of Illness to Look Out For

Unfortunately, molly is sometimes sick molly. Mollies have not been described in this article before, but they do not eat loaches, and other mollusks like loaches if they are.

If your fish does not have a pregnancy, you must first see any signs of common fish diseases.

3 Reasons Why do Mollies Stay at the Top of the Tank

Mollies are little tropical fish but active. They will have plenty of room for exploration. If a man spends too much time on the top of the tank, he will be responsible for the following:

Your Molly isn’t Happy in its Tank

Sometimes, the Mollies jump on the top and stay there because they lack oxygen. They often try to avoid lower-class conditions, such as a lack of oxygen or higher temperatures.

Usually, if you are providing the right soft water conditions, they will stay near the bottom.

But before that happens, they have trouble breathing. If you look carefully, the gills are inflamed.

The gasps for breath will be visible, which generally indicates the tank is devoid of oxygen. If it is a tank where oxygen has been checked, it must be checked for ammonia. Molly runs to the surface to ward off Ammonia nitrates and nitrites. They will remain on top until there is a solution.

The fish needs to get more oxygen.

When fish hang over their surface, they are immediately concerned to produce oxygen in the water. This happens because adult fish gills take oxygen from the seawater.

Naturally, oxygen evaporated in tanks by surface vaporization. In case of a drastic oxygen drop, the only rational solution is to rush into the water to rehydrate it and maintain a healthy oxygen level.

A molly fish with an oxygen shortage will also rapidly gasp and open its mouth. Molly may end up lazy because they need to swim more effectively.

Your molly is stressed.

Stress can force fish to perform unnatural actions. Then you either lay still under the tank or stay on top. Stress has a lot of causes, including lack of water conditions and bullies.

It is also worth mentioning that if you have recently placed your molly in the tank, it can take up to a few weeks to get used to the new environment. During this period, it may remain stuck at the top of the tank as it is trying to adjust.

Is It Normal for Mollies to Swim at Top of Tank?

Yes, it is normal for Mollies to stay at the top of the tank. This behavior can be attributed to their instincts, lack of oxygen in the tank, stress, or poor water conditions.

It is crucial to properly monitor and maintain the water parameters to ensure your Mollies stay healthy and happy!

If you notice any changes in the behavior of your hardy fish, it is vital to act quickly and provide the necessary treatment.

By understanding the symptoms of common molly illnesses and taking steps to maintain optimal conditions in their tank, you can easily ensure that your mollies stay healthy and happy.

Do Molly Fish Sleep on Bottom of Tank?

Molly fish can sleep either at the bottom or middle of their tank. The exact position will depend on their mood and water conditions.

If the water is too cold, they may tend to lay closer to the substrate in search of a warmer environment. They may also rest near hiding spots, providing a sense of security from potential predators.

It is important to note that Mollies do not need to rest on the bottom of the tank to survive and can move freely around their habitat.

However, if you notice that your molly is sleeping at the bottom for an extended period, it could be a sign of poor water quality or illness and should be monitored closely.

How To Prevent Common Molly Illnesses

If the water inside your tank is a problem, it must be appropriately treated. The easiest solution is to use garlic. Garlic can be used as a promising treatment for ICH because it’s incredibly antiparasitic.

A little garlic is inserted in the fish tank so the fish will not get sick and should be nourished. Garlic has been proven to be bacterial and antifungal, so it can reduce symptoms and prevent rot.
