Very rare in the aquarium trade, Ancistrus claro LDA-08 is a sought-after form sold under the name Gold Marble. This small South American loricariid is recognized by its stocky body, sucker mouth and gold-and-brown marbling, which stands out especially against a dark layout. Because it is a wild-collected fish, acclimation deserves special attention: clean water, strong oxygenation, hiding places and regular vegetable foods are essential. This form is exclusive to Ton.Fish in Canada and will appeal mainly to aquarists looking for a rare, discreet bottom-dweller whose behavior reflects the natural habits of Ancistrus.

General species description

Ancistrus claro LDA-08 is a small to medium-sized Ancistrus kept mainly for its distinctive appearance and surface-grazing behavior. It spends much of its time attached to aquarium glass, roots, stones or leaves, especially during low-light periods. Activity often increases in the evening and at night. Despite its sturdy appearance, it is sensitive to waste accumulation and poor oxygenation. A mature, well-filtered aquarium decorated with natural wood is more suitable than a bare setup. This form remains very rare in the trade and should be considered a specialized acquisition rather than simply an algae eater.

Geographic origin and habitat

The stated origin of Ancistrus claro LDA-08 is Brazil, in the Rio Cuiabá basin. Its natural environment consists of freshwater areas where fish can graze on surfaces and shelter among branches, stones and submerged wood. Water movement may range from moderate to strong depending on the area, with good oxygen availability. In the aquarium, aim for a clean, well-circulated and biologically stable stream environment without creating current so strong that the fish cannot feed. Regular water changes and efficient filtration are especially important for a wild-collected specimen.

Precise locality and local name

The river origin supplied for Ancistrus claro LDA-08 is the Rio Cuiabá in Brazil. The most commonly used aquarium name is Gold Marble, referring to its color pattern. The LDA-08 code identifies it within the aquarium trade when the complete scientific designation is not used. This code does not replace a detailed collection locality, but it helps hobbyists recognize this form among South American catfish. To preserve its identity, it is best to keep fish from this strain separate from similarly marked Ancistrus.

Appearance and physical characteristics

Ancistrus claro LDA-08 has a flattened underside and a body covered with bony plates, along with a broad head and an inferior mouth adapted for attachment and scraping. The Gold Marble coloration combines a brown, gray or golden base with irregular darker markings, creating a variable marbled pattern from one fish to another. The fins are generally sturdy and proportionate to the body. As in other Ancistrus, mature males may develop tentacles on the head, while females show few or none. Adult size remains moderate, but an aquarium with ample bottom area and several shelters supports steady growth.

General diet

Ancistrus claro LDA-08 is primarily herbivorous with an omnivorous tendency. Its diet should be based on spirulina tablets, sinking vegetable foods and blanched vegetables such as zucchini, cucumber or spinach. A regular source of fiber is important for digestion and reduces dependence on algae naturally growing in the aquarium. It also accepts a small amount of protein-rich food, especially when young or after acclimation, but this should not dominate the diet. A genuine piece of driftwood is recommended as a grazing surface and as a natural part of the layout.

In your aquarium, success with Ancistrus claro LDA-08 depends on stable, clean and well-oxygenated water, a layout offering several refuges and vegetable foods offered after the lights have been partly dimmed. Because this fish is very rare, wild collected and exclusive to Ton.Fish in Canada, repeated handling should be avoided and acclimation should be gradual. A piece of driftwood, quality sinking foods and fresh vegetables will help maintain its condition and display its marbled pattern.
