Diet for Yellow Flagtail Prochilodus

Aquarium Setup Yellow Flagtail Prochilodus

Aquarium Filtration

Use powerful mechanical and biological filtration to manage their substantial waste production. Strong oxygenation and regular water changes are important for maintaining excellent water quality.

Aquarium Plants

Hardy plants can be used, although softer plants may be grazed or disturbed. Robust species attached to rocks or driftwood are generally better choices.

Aquarium Lighting

Moderate lighting is suitable, with some shaded areas providing shelter and allowing fish to retreat from intense illumination.

Aquarium Heating

Maintain a stable temperature of approximately 24–28°C. Avoid sudden temperature changes and ensure strong oxygenation at warmer temperatures.

Aquarium Substrate

Fine sand or smooth gravel is suitable and provides a natural-looking base for the aquarium. Avoid sharp substrates that could cause injury.

Aquarium Decorations

Use large pieces of driftwood, smooth rocks and robust decorations to create structure while retaining substantial open swimming areas. Ensure all decorations are securely positioned, as active Prochilodus can disturb loose objects.
