What Does a Green Dragon Bristlenose Eat?

Feed a Variety of Plant-Based Foods

Green Dragon Bristlenose Plecos are excellent grazers, but naturally occurring algae alone should not be considered a complete diet.

Recommended Foods

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

Small amounts of protein-rich foods can also be incorporated into a balanced diet.

Feeding Tip

Offer food in the evening when the aquarium lights are dimmed.

This allows the pleco to feed during its most active period while reducing competition from faster-moving aquarium fish.

Behaviour and Temperament

Peaceful and Active After Dark

The Green Dragon Bristlenose is generally a peaceful community fish.

You may see it:

• Grazing aquarium glass
• Feeding on driftwood
• Exploring rocks
• Searching for food
• Moving through caves
• Resting beneath décor

Males can become territorial toward other male bristlenose plecos, particularly when suitable caves are limited.
