Species profile
Satanoperca jurupari
Common names: Demon Eartheater, Jurupari Eartheater

A peaceful, social sand-sifting cichlid that needs a large group, pristine water, and a broad bed of fine sand.
A tall silver-gold eartheater with blue-green iridescence, reddish fins, and a small dark flank mark that may be faint.
The Satanoperca jurupari group contains several similar species. Opercular lines, flank spots, fin pattern, locality, and adult morphology should be checked.
Sexes are similar. Mature males may be larger and longer-finned, while ripe females become fuller.
Keep at least five or six over a wide bed of fine sand with powerful filtration, high oxygen, wood, and open swimming room. Avoid sharp substrate and cramped décor.
Peaceful for its size, highly social, and continuously sifts sand for food.
A group forms a hierarchy. Small groups produce persistent bullying and should be avoided.
Pairs defend a temporary spawning area but usually return to group life outside breeding.
Suitable with peaceful medium to large South American fish that do not dominate the bottom. Small fish and shrimp may be eaten.
Stable warm, clean, well-oxygenated water is essential. The species is prone to stress and head-and-lateral-line erosion in poor conditions.
