Thorichthys aureus

Thorichthys aureus takes its name ("golden") from the yellow–gold tones of its body. There are shiny blue spots on the scales and gill covers, and a dark blotch in the middle of the body. In mature males the tips of the dorsal and anal fins extend beyond the tail; this is an elegant feature that sets the species apart from its relatives. Like the other species of its genus, it feeds by sifting sand and displays by flaring its gill covers when threatened.

• At least 150 liters and 100 cm of length for a pair.
• Fine sand substrate is a must; a large open sand area.
• Rocks and roots; plants are safer if attached to rocks.
• Moderately hard, slightly alkaline water; change 25–30% weekly.

Omnivorous. Make small sinking granules and tablets the staple; vary them with frozen bloodworms, brine shrimp and mysis. Make sure the food reaches the bottom.

Relatively mild; it guards the area around the eggs during breeding. It is tougher toward males of its own species.

Good companions: other Thorichthys species (in a large aquarium), rainbow cichlid, large livebearers, barbs, plecos.

Avoid: very small fish and shrimp, large aggressive cichlids.
