Blue Dolphin
Blue Dolphin (Cyrtocara moorii) is one of the most distinctive cichlids from Lake Malawi. The common name comes from the prominent nuchal hump that develops on the forehead of adult males — combined with the pale blue body and rounded snout, the overall profile truly resembles a dolphin. This is a large, peaceful haplochromine that makes a magnificent centerpiece in a Malawi community aquarium.
Feeding & Care Tip: Hikari Cichlid Bio-Gold is the ideal staple — Hikari Micro Pellets as backup. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Baby Brine Shrimp. Feed near the substrate to encourage natural foraging behavior.
Lake Malawi is a large, deep, alkaline lake with remarkably stable water chemistry. Hard, alkaline water with excellent filtration and regular water changes are essential. Crushed coral or aragonite substrate helps maintain the required pH and hardness. Provide plenty of rockwork to create territories and sight-breaks — this significantly reduces aggression by giving subordinate fish refuge from dominant males.
Keep one male with two or more females. The Blue Dolphin is one of the more peaceful large Malawi cichlids and mixes well with Aulonocara peacocks and other non-aggressive haplochromines. Avoid aggressive mbuna that will intimidate this gentle giant. Needs a larger aquarium — at least 4 feet for a proper group.
The nuchal hump of adult males develops gradually over 2–3 years and is most impressive in dominant males in excellent conditions. Patience is rewarded — a fully developed adult male Blue Dolphin is one of the most impressive fish in the Malawi hobby. The Blue Dolphin also has a fascinating habit of following other cichlids to pick up invertebrates disturbed by their digging — a commensal behavior unique among Malawi cichlids.
