Recommended Aquarium Features

• Mature biological filtration
• Good water circulation
• Strong oxygenation
• Aquarium-safe driftwood
• Pleco caves
• Smooth rocks
• Shaded areas

What Does a 2″ LDA72 Bristlenose Eat?

Provide a Balanced Diet

The LDA72 naturally grazes on algae and biofilm, but aquarium algae should not be its only food source.

Suitable foods include:

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

For a young 2-inch pleco, appropriately sized sinking foods are particularly useful.

Feeding Tip

Offer food in the evening or after the aquarium lights have dimmed. Bristlenose plecos are generally more active during the evening and nighttime.

Remove uneaten vegetables before they begin to decompose.

Behaviour and Temperament

Peaceful Bottom Dweller

The LDA72 Bristlenose is generally peaceful and can be kept with many compatible freshwater community fish.

During daylight, it may rest beneath driftwood or inside a cave. Once the aquarium becomes darker, it typically becomes more active.

You may observe it:

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

Males can become territorial toward other males, particularly around preferred caves.

Suitable Community Fish

Potential tank mates include:

• Tetras

• Livebearers
• Small South American community fish
• Other compatible peaceful tropical fish

Avoid

• Aggressive predators

A peaceful community environment is especially important for a young 2-inch specimen.

Breeding LDA72 Bristlenose

When mature, breeding fish can be provided with:

• Suitable spawning caves
• Excellent water quality
• Strong oxygenation
• Stable temperatures
