Foods that Molly Fish Should not be Fed With
Meats from land animals such as beef and chicken should not be fed to the mollies. This is because they cannot digest too much meat protein. Some live plants are toxic for molly fish such as lilies and water lilies.
If your mollies fish is showing no interest in food, you should investigate quickly before this starvation can be fatal. Following are some potential causes that you should investigate:
A common occurrence in fish is constipation. The most prominent cause of constipation is overfeeding. This condition can prevail by the purchase and feeding of poor-quality food items. The feeding method can be at fault too. Some dry foods can expand in your molly’s stomach blocking the digestive tract. A constipated molly fish will either eat little or no food. A molly fish is likely suffering from this condition if it swims slowly, is bloated, or hides in the bottom of the tank.
Molly fish are open to many diseases, infections, and parasites. They lose their appetite whenever they fall sick. There are various illnesses that have different symptoms. For example, irregular and unstable swimming can point to swimming bladder disease and dropsy. Fuzzy growths can point to fungal or bacterial infections.

If your mollies are not eating, it is possible that the quality of the water has dropped.

Suddenly changing the environment can induce stress in the molly causing a loss in appetite.
- Water Temperature
Wrong water temperature can not only induce stress but also slow down molly’s metabolism, making it lethargic. As a result, it stops eating and spends more time sitting in one place. Hot water can cause oxygen deficiencies while cold water can cause the molly to become lethargic.
- New Habitat
Mollies that are not accustomed to a tank go into hiding. This is because they’re new to the habitat. This will induce stress making the molly lose its appetite. However, this condition is not a problem as you have to wait for the molly to get used to the new environment.
Pregnancy makes mollies lethargic due to which they spend less time swimming and stop eating as a result.
