Sexing L183 Starlight Plecos

[lilacamy931]

Have a group of 4 starlight bristlenoses and a standard. Unsure if they are two young to sex?

This is the standard - biggest and longest been with me, growing well. Think female? About 2.5 inches.

The two new additions managed to remember take pic before going in tank:

And...a different shot hopefully of one of the others!!

I love the L183's.... nice looking plecs! L183's should be around 3" and up to sex correctly so not to far away...... That being said, some pictures in a container (best with something white under them) with them laying flat and the pictures taken from the top and side would be best to sex them. You can fairly accurately sex most plecs by the fin size/shape/thickness and body shape..... that is why you need good pictures from above and the side. In the bag picture and at angles can make it imposable to sex them correctly.

Thank you again for your expertise. The standard I can possibly and suspect female, the others are far too small right now. I shall wait a couple of months for growth and see if can cordone them to see if have a mix - thank you again!
