Red Banded Leporinus (Synaptolaemus latofasciatus)

Synaptolaemus latofasciatus – Red Banded Leporinus

The Red Banded Leporinus is a striking and energetic South American characin known for its bold vertical red and black banding over a golden base. Sleek, fast, and constantly on the move, this species brings color and activity to larger community or semi-aggressive aquariums.

Unlike many smaller tetras, the Red Banded Leporinus grows into a substantial, powerful fish that thrives in spacious tanks with strong filtration and current. When kept properly, their colors intensify and their schooling behavior becomes more pronounced, making them a standout display species.

This is an excellent option for aquarists looking for something different — a fish with personality, motion, and bold natural patterning.

Adult Size

• Typically reaches 8–12 inches in captivity

• Fast swimmer with a strong, torpedo-shaped body

---

Tank Size

• Minimum: 75 gallons (juveniles)

• Recommended: 125 gallons or larger for adults

• Best kept in groups of 3–5 or more to reduce aggression and encourage natural behavior

Aquascape Tips:

• Open swimming space is essential

• Secure décor (they are active and strong)

• Driftwood and rock structures for visual breaks

• Tight-fitting lid (they can jump)

---

Water Parameters

• Temperature: 75–82°F (24–28°C)

• pH: 6.0–7.5

• GH: 3–12 dGH

• Nitrate: Ideally under 20–30 ppm

They are hardy but require stable water quality and strong filtration due to their activity level and size.

Tank Mates

Red Banded Leporinus are semi-aggressive and may nip fins, especially if kept alone or in undersized groups.

Good tank mates:

• Larger South American cichlids (non-delicate species)

• Silver dollars

• Larger tetras

• Robust catfish (plecos, larger Corydoras in large systems)

• Other similarly sized active fish

Avoid:

• Long-finned or slow-moving fish

• Very small community species

• Timid tank mates

• Overcrowded setups

When kept in proper group sizes and adequate tank space, aggression is significantly reduced.

Feeding

Omnivorous with a strong appetite.

• High-quality pellets (sinking and floating)

• Vegetable matter (spirulina, blanched spinach, zucchini)

• Frozen foods like bloodworms or brine shrimp

• Occasional protein-based treats

Providing vegetable matter helps reduce plant nipping and keeps them in peak condition.
