Yellow and Black Molly Fish
Also known as gold dust, this fish has half its body yellow and the other half black. The yellow part is the head, while the black part is the tail.

Basic Molly Fish Care
As mentioned earlier, Molly fish are very easy to care for and are perfect for those who are new to the fish world. Since they are found throughout most of the continental United States, these fish have been able to adapt to different types of water and habitats.
As far as diseases are concerned, they are prone to parasitic diseases, such as fungal attacks or white spot. The most common disease in these fish is Molly’s disease, caused by a bacterium called Collumnis, which causes a deformation of the fish’s spine.
To know if a fish has been attacked by this bacterium, you should check if white spots have appeared on its skin, if it shakes or if it remains lethargic. If there is a sick fish in the aquarium, it is best to isolate it and start a treatment with terramycin and potassium permanganate.
Feeding Molly fish
Molly fish are omnivorous and feed in the wild on algae, vegetation and small invertebrates. In aquariums, they can be fed green vegetables such as zucchini, lettuce or spinach, as well as shelled cucumbers and peas.
Their protein source is live and frozen foods such as brine shrimp, bloodworms or daphnia. In addition, their diet can be supplemented with pellets or flakes.
Ideally, they should be fed twice a day, always in small quantities, and enough to finish within two minutes, so that their digestive system can process all the food.
