How Large Does an L144 Bristlenose Grow?

Aquarium Size and Setup

Recommended Aquarium

A 30-gallon aquarium or larger can be suitable for an adult L144, depending on stocking levels and available bottom territory.

For multiple bristlenose plecos, provide a larger aquarium with several separate hiding places.

Recommended Aquarium Features

• Mature biological filtration
• Good water circulation
• Strong oxygenation
• Aquarium-safe driftwood
• Pleco caves
• Smooth rocks
• Shaded areas
• Open bottom territory
• Surfaces for grazing

Driftwood and Caves

Driftwood provides valuable grazing surfaces and shelter.

Caves are equally important because bristlenose plecos naturally seek enclosed spaces for resting and, when breeding, spawning.

What Does an L144 Blue Eye Bristlenose Eat?

Give Your Pleco a Balanced Diet

L144 Bristlenose Plecos are excellent grazers, but naturally occurring aquarium algae should not be their only source of nutrition.

• Blanched zucchini
• Cucumber
• Green beans
• Spinach
