What Does a Green Dragon Bristlenose Eat?

Give Your Pleco a Balanced Diet

Green Dragon Bristlenose Plecos are excellent algae and biofilm grazers, but natural algae alone is not a complete diet.

Recommended foods include:

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

Occasional protein-rich foods can also be included as part of a varied diet.

Feeding Tip

Feed sinking foods in the evening after the aquarium lights are dimmed. This allows the pleco to feed during its naturally active period.

Behaviour and Temperament

Peaceful and Mostly Nocturnal

The Green Dragon Bristlenose is generally peaceful and can be an excellent community aquarium fish.

During the day, it may spend considerable time inside caves, underneath driftwood, or in shaded areas.

After the lights go down, it becomes more active and may be seen:

• Grazing aquarium glass
• Exploring driftwood
• Searching for food
• Moving across rocks
• Exploring caves
• Resting beneath décor

Males may become territorial toward other males, particularly when there are not enough caves.
