Redfin Flagtail Prochilodus (Semaprochilodus taeniurus)

Redfin Flagtail Prochilodus (Semaprochilodus taeniurus)

Quarantined large algae-grazing characin for carefully planned freshwater aquariums in Canada.

The Redfin Flagtail Prochilodus is a large, active South American fish known for its red fins, striped tail, and constant grazing behaviour. It is a specialty display fish for large aquariums, not a small cleanup fish.

Why This Fish Stands Out

• Impressive large South American display fish
• Attractive red fins and striped tail pattern
• Active grazer with strong movement

Aquarium Setup & Behaviour

Provide a large aquarium with open swimming space, strong filtration, and robust tankmates. It may graze on soft plants, so planted-tank planning is important.

Can be active and boisterous. Choose tankmates carefully and plan for adult size.

Feeding

Offer vegetable-based foods, algae wafers, quality pellets, and varied supplementation.

Natural Colour & Livestock Integrity

Colour is natural and supported by health and diet. No hormones are used to artificially enhance colour.

Topick Aquarium Livestock Standard

All fish at Topick Aquarium are carefully quarantined and conditioned to our stable local tap water before sale. Some oddball and specialty species still have very specific long-term needs, so we recommend matching each fish to the right aquarium size, diet, tankmates, and maintenance routine before purchase.
