The OB Peacock is a striking African cichlid commonly sold under the Aulonocara (Peacock) name. “OB” stands for Orange Blotch, referring to the irregular orange/red/black blotching pattern across the body and fins. Unlike a naturally occurring, formally described species, OB Peacocks in the aquarium trade are generally captive-bred color strains/hybrids, so their exact lineage can vary between breeders.
🔎 Quick Facts – OB Peacock (Aulonocara sp.)
😇 Behavior & Temperament
Because OB coloration can come from mixed or selectively bred lineages, temperament and appearance can differ between individual fish and breeders.
🏠 Aquarium & Tank Requirements
For a Malawi community, maintaining appropriate stocking and providing plenty of visual breaks can substantially reduce aggression.
💧 Water Parameters – OB Peacock Care
Stable water quality is generally more important than chasing an exact number.
🍽️ Diet – Omnivorous / Insectivore
OB Peacocks should receive a varied diet based around quality foods formulated for African cichlids:
Avoid making very fatty or mammalian-protein-heavy foods a staple. A balanced Malawi-cichlid diet is a better choice.
🧬 Breeding
If maintaining a particular OB strain, knowing the breeder's lineage is especially important because “OB Peacock” isn't a single standardized species.
