Daemon Eartheater

Satanoperca daemon is the most dramatic member of its genus, reaching over 30 cm and bearing three large, yellow-orange rimmed ocelli on a dusky, almost black body that shimmers with iridescent blue under side-lighting. It is a flagship species for the dedicated blackwater cichlid keeper and commands significant respect among South American cichlid enthusiasts worldwide.

This species is strictly a blackwater fish, requiring soft, warm, highly acidic water with very low mineral content. Water tinted with botanical additions — Indian almond leaves, alder cones, and driftwood — is strongly recommended. It is highly sensitive to nitrate accumulation and requires pristine conditions maintained by strong filtration and frequent partial changes.

Despite its imposing size, Satanoperca daemon is a gentle giant and thrives in the company of large, peaceful tankmates. Breeding in captivity is an achievement reserved for experienced keepers who can maintain blackwater conditions consistently.
