Sphaerichthys osphromenoides is generally considered to be a maternal mouth brooder. That is to say; the female incubates the eggs in her mouth.
If that is wrong, and osphromenoides is actually a paternal mouth brooder, then it follows that all the advice on sexing osphromenoides is also wrong.
So let's bust the myth of maternal mouth brooding in osphromenoides.

The fish with the three spots on the anal fin is female, the other fish is male.
Keep this in mind when you watch the following video. Watch who lays the eggs and who picks up the eggs.
Here is another spawning:
(I would have liked to have given the 'media tag' a larger size for the videos. Perhaps not possible?)
