Asking for Gender ID

  • We are currently upgrading MFK. thanks! -neo
With the grammodes the head shape and facial striations work good in older fish but can be difficult to read in younger fish. Especially when you raise a single specimen.
But you can easily sex them by the red pattern on their bellies. Red spots = male, red honeycomb pattern = female. This works already with a few months old fish at 1.5 - 2" length because the pattern doesn't change much over time.

I was told this also works with D. calobrensis.

Also note on Milingu's pair, the spots on the cheek and jaw of the male, as opposed to the more linear striations of the female.
Mine were similar.
male above.
I encourage anyone that has photos that show obvious gender differences of fish not yet here, or already shown, to post in the thread.

Above male, below female both in spawning dress, note the obvious cranial profile different shape

The genus Andinoacara are notoriously difficult to tell apart when not spawning

The female A coerleopunctatus (above) has a slightly boxier body, and her colors slightly darker (at times)
Male below, longer fin extensions, slightly more streamlined body, lighter overall base color
