Tipy pro identifikaci

1. 1

   Body Shape and Size

   Generally robust, laterally compressed bodies. Size varies by species, typically ranging from 8 cm to 15 cm (3 to 6 inches) in total length.

2. 2

   Coloration and Pattern

   Observe the specific combination of colors (blue, yellow, black, orange) and patterns (bars, stripes, blotches). This is often the primary identifier for different species within the genus or related genera.

3. 3

   Mouth and Teeth Structure

   Their mouth is adapted for scraping algae from rocks. Examination of the teeth (if possible) can help differentiate between species with different feeding specializations.

4. 4

   Egg Spots

   Presence and number of ocelli (egg spots) on the anal fin, particularly in males, can be a distinguishing characteristic for some species.

5. 5

   Geographic Locality (in wild)

   For wild specimens, the specific collection point within Lake Malawi is crucial for accurate identification, as many species are localized endemics.
