Sexing Ancistrus L213

[emanuel]

Is anyone able to figure out the sex of these two Ancistrus L213 from this video?

Six months ago, I picked them out of a group because they seemed to have a small difference in head shape, but they haven't bred yet, so I'm afraid they are of the same sex. I would like to understand if male or female.

Both are male. Males have bristles going up the nose.... females may have them around the mouth but are normally smaller and do not go all the way up the nose.

Take care,
Chuck

Thanks for the reply. I will go in search of a female
