Bestimmungstipps

1. 1

   Body Shape and Size

   Goldmolly hybrids typically reach 5-10 cm (2-4 inches) in length. Females are generally larger and more robust than males.

2. 2

   Coloration

   The most striking feature of the Goldmolly is its vibrant golden-yellow color, which distinguishes it from most wild-type mollies.

3. 3

   Dorsal Fin (Males)

   Observe the dorsal fin. If it is exceptionally large and sail-like, it indicates a strong P. latipinna influence. A shorter, more rounded dorsal fin suggests P. sphenops influence or a hybrid with less P. latipinna genetics.

4. 4

   Gonopodium (Males)

   Males can be identified by their modified, rod-like anal fin (gonopodium), which is absent in females.
