Identification Tips

1. 1

   Body Shape

   Look for the characteristic oval, compressed body, distinct from the more elongated or deeper-bodied cichlids.

2. 2

   Vertical Bars

   Observe the presence of 8-9 vertical bars, especially in juveniles or when the fish is stressed or displaying. These may fade in adult specimens or certain color morphs.

3. 3

   Caudal Fin Spot

   A dark spot or ocellus at the base of the caudal fin is a common, though not always prominent, identifying feature.

4. 4

   Lip Structure

   Notice the relatively thick, fleshy lips, which are characteristic of the genus Heros.

5. 5

   Coloration

   While variable, the base coloration often includes greenish, golden, or reddish tones. Specific captive strains like 'Rotkeil' have distinct red markings.
