Green Dragon Bristlenose Longfin (Ancistrus sp. Green Dragon) for Sale in Canada

The Green Dragon Bristlenose Longfin is a striking specialty bristlenose pleco admired for its attractive green-toned coloration, compact body, and elegant elongated fins. This unique Ancistrus variety is an excellent choice for freshwater aquarists who want a beautiful bottom-dwelling fish with plenty of personality.

The longfin form gives this Green Dragon Bristlenose an especially attractive appearance. Its extended dorsal and caudal fins create a flowing look as it moves around the aquarium, while its sucker mouth and armored body give it the classic appearance associated with bristlenose plecos.

The Green Dragon Bristlenose is also a useful aquarium resident because it naturally grazes on algae, biofilm, and other surfaces. However, it should still receive a complete and varied diet.

Monster Aquarium Canada offers specialty freshwater fish for Canadian aquarists looking for distinctive plecos and unusual aquarium species.

What Does a Green Dragon Bristlenose Eat?

Give Your Pleco a Varied Diet

Although bristlenose plecos are excellent grazers, naturally occurring algae should not be their only food source.

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

Feeding Tip

Feed after the aquarium lights have dimmed, when the pleco is more likely to become active.

In a community aquarium, make sure the Green Dragon receives enough food rather than allowing faster fish to consume everything first.

Behaviour and Temperament

Peaceful, Interesting and Mostly Nocturnal

The Green Dragon Bristlenose Longfin is generally peaceful and can work well in a community aquarium.

During daylight hours, it may rest underneath driftwood, inside caves, or in shaded areas. Once the aquarium becomes darker, it will often emerge to explore and feed.

You may see your pleco:

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

Males can become territorial toward other male bristlenose plecos, particularly when hiding places are limited.

Compatible Tank Mates

Excellent Community Aquarium Fish

Green Dragon Bristlenose Plecos can live with many peaceful tropical fish.

Potential tank mates include:

• Tetras
• Rasboras
• Corydoras
• Gouramis
• Peaceful dwarf cichlids
• Livebearers
• Small South American community fish
• Other peaceful tropical fish

Avoid

• Aggressive predators
• Highly territorial fish
• Persistent fin-nippers
• Fish that constantly harass bottom dwellers
• Excessive competition for caves

Because this is a longfin variety, avoid tank mates known for persistent fin-nipping.
