What Do the Oscars Eat

Pellets and Their Importance

Vitamin C is important for fish as it helps with healing wounds as well as bone and tooth formation. Vegetables provide fish with vitamin C and many other essential nutrients that are vital for their existence.

Pellets are a great option for feeding Oscar fish. They provide a balanced diet with both protein and plant-based nutrients. Just make sure to choose high-quality pellets from reputable brands to keep your Oscars healthy.

High Astaxanthin content in pellets enhances the vibrant red coloration of Oscars, making it a crucial choice for their diet. If you decide to go with a pellet, we recommend a floating pellet over a sinking one.

You can complement pellets with vegetables, live food, frozen food, and fruits to create a well-rounded diet for your Oscars.
