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.
