Heterodon Pleco (L172)

The heterodon pleco is the smallest member of the genus Leporacanthicus, known as the "vampire" plecos. Its dark body is decorated with small golden-yellow spots, which is why it is also called the "golden vampire". In the trade it is sold under the number L172 or L172a.

Sources give its length as between 10 and 18 cm; in the aquarium, fish of 12–16 cm are common. Like other members of its genus, it hunts snails and small invertebrates with its long upper teeth.

• At least 200 liters and 100 cm length for one fish.
• Strong flow and aeration; caves that fit its body and rock piles.
• 27–29°C, a 30% water change every week.

Carnivorous. Make pieces of mussel and shrimp, bloodworms, mysis and protein-rich sinking tablets the staple; it loves live snails. It accepts small amounts of vegetables.

It usually leaves other fish alone but defends its cave. Snails and small shrimplets become its prey. It is nocturnal and stays in its cave during the day.

Good companions: Calm, medium-sized fish that like warm water: tetras, dwarf cichlids, corydoras.

Avoid: Snails, dwarf shrimp, other Leporacanthicus species (in limited space).
