Hypancistrus sp. L066
Also known as King Tiger Pleco, L066
Animalia›Chordata›Siluriformes›Loricariidae
The L066 King Tiger Pleco is a stunning small pleco species featuring bold black and white striped patterns that make it highly sought after by aquarists. This nocturnal bottom-dweller is relatively peaceful and does well in established tanks with plenty of hiding spots and driftwood. It's an excellent choice for intermediate aquarists looking to add a visually striking pleco to their collection.

Care
Diet
Feed high-quality sinking pellets, algae wafers, and blanched vegetables like zucchini and spinach 3-4 times weekly. Supplement with occasional protein sources such as bloodworms or small crustaceans. Provide driftwood for natural grazing and wood consumption, which aids digestion.
Behavior
The L066 is primarily nocturnal and spends most daylight hours hiding in caves or under driftwood. They are generally solitary and peaceful with other fish, though males may be territorial toward each other. They are active foragers at night and will scavenge the tank bottom for food.
Breeding
Breeding in captivity is challenging and rarely achieved in home aquariums. Males are highly territorial and require separate caves; females are difficult to condition. Successful breeding requires pristine water conditions, abundant hiding spaces, and careful monitoring of pair compatibility.
