Calico Bristlenose Size

Larger aquariums are recommended for multiple specimens.

Recommended Aquarium Features

• Strong oxygenation
• Aquarium-safe driftwood

What Does a Calico Bristlenose Eat?

Provide a Varied Diet

Calico Bristlenose Plecos naturally graze on algae and biofilm, but aquarium algae should not be their only food source.

Recommended foods include:

• Algae wafers
• High-quality sinking pleco pellets
• Vegetable-based foods
• Blanched zucchini
• Cucumber
• Green beans

Behaviour and Temperament

Peaceful Bottom Dweller

The Calico Bristlenose is generally peaceful and works well with many compatible freshwater community fish.

During daylight, it may spend much of its time hiding beneath driftwood or inside a cave. Once the aquarium becomes darker, it generally becomes more active.

You may observe it:

• Grazing aquarium glass
• Feeding on biofilm
• Exploring driftwood
• Searching for food
• Moving across rocks
• Exploring caves

Male bristlenose plecos can become territorial toward other males, particularly when hiding places are limited.

Avoid
