The wild Blue discus from the Rio Negro and surrounding tributaries. Distinct from the captive-bred designer lines (Blue Diamond, Cobalt, Royal Blue) - wild specimens have more subtle, naturalistic blue patterning.
Wild Blue discus demands soft acidic water (pH 5.5-6.5, GH 1-4, KH 0-1, temperature 82-86°F). Far more demanding than tank-bred designer discus. Requires RO/DI water remineralized lightly.
