OK, thanks a lot for that, Klaus!
My "juvenile Ancistrus punctatus", is 3" (7,5cm), it could be juvenile at this size?

Really???
But they appear very similar... just the end of caudal and dorsal fins have a small difference in color.
But on the pic. #1, the female was stressed a little, therefore it had not taken its true colors

Pic. #1: female L237??
Pic. #2: Female (vertic.) and male (horiz.)L237??

Pic. #3 & 4 ...

Hy!
I have buy the first fish as "L059" but i think is L279

the femelle is on the glass and the male on the ground ...

Thank you very much. I had made a research in the forum, but I was not to go up so far in the date.
That gives me finally an answer which is appropriate to me.
Thank you!

Chris.

Hello!
I'm a newbies in Locaridae, and i would to know in what the bristles are useful on the nose of the ancistrus (male)?
It is like the other species where the male is more coloful, or it has larger fins, etc ...?
Or it's maybe like cat's mustaches, to give their gauge when it enters a tunnel ...
