What Does a Calico Bristlenose Eat?

Provide a Varied and Nutritious Diet

Calico Bristlenose Plecos naturally graze on algae and biofilm, but aquarium algae alone should not be considered a complete diet.

Recommended foods include:

• Spirulina wafers
• Algae wafers
• High-quality sinking pleco pellets
• Vegetable-based foods
• Blanched zucchini
• Cucumber
• Green beans
• Spinach
• Kale
• Quality gel foods

A varied diet helps support healthy growth and condition.

Feeding Tip

Feed sinking foods in the evening after aquarium lights are dimmed. This allows the pleco to feed when it is naturally most active.

Behaviour and Temperament

Peaceful Bottom-Dwelling Fish
