How to Identify Cobalt Zebra Cichlid

To identify Cobalt Zebra Cichlid (Maylandia callainos), look at these key features.

Physical Characteristics

Body shape

compressed

Coloration

Predominantly brilliant blue, ranging from light sky blue to deep cobalt. Some individuals may exhibit faint vertical barring, especially when stressed or during breeding. Females are typically less intensely colored than males, though some populations have equally vibrant females. The 'Pearl Zebra' variant has a more iridescent, almost white-blue hue.

Scale type

ctenoid

Mouth position

terminal

Distinctive features

Intense blue coloration, Robust, somewhat elongated body typical of mbuna cichlids, Males often develop egg spots on the anal fin, Relatively small, terminal mouth adapted for scraping algae

Dorsal fin

Long, continuous dorsal fin with spiny anterior rays and softer posterior rays. The spiny portion is typically longer than the soft-rayed portion.

Tail fin

Caudal fin is typically rounded to truncate.

Pectoral fin

Paired pectoral fins are relatively small and clear.

Distinctive fins

Anal fin of males often features prominent yellow or orange ocelli (egg spots), which play a role in breeding behavior.

Identification Tips

1. 1

   Coloration

   The most distinguishing feature is its vibrant blue color. While other mbuna can be blue, the intensity and specific shade of blue in M. callainos are often unique. Look for the pearlescent sheen in some variants.

2. 2

   Body Shape

   Typical mbuna body shape: robust, laterally compressed, and somewhat elongated. It lacks the pronounced vertical barring seen in many other 'zebra' cichlids (e.g., Maylandia zebra complex), though faint bars may appear.

3. 3

   Egg Spots

   Males will display distinct yellow or orange egg spots on their anal fin, which are used to entice females during spawning. The number and prominence of these spots can vary.

4. 4

   Mouth Structure

   Its small, terminal mouth is adapted for scraping algae from rocks, a key characteristic of mbuna cichlids.
