This was the one I think could be a female!

Seems almost all the fish have the hairs on the pectoral fins. This smaller all black one seems to be a possible female!

Thanks so much and excellent information I really appreciate the messages!
I'm starting to think all the fish are males. I'm wondering if the exporters keep the females?

I just got a big group of yellow chubby plecos. Some are pretty large almost 10"!
Anyone know if this bigger one is a male or female?
Thanks in advance!

Just wanted to ask about Gulper Catfish! I know there ferocious.
Would a gulper catfish kill himself trying to eat a yellow chubby of the same size or will he mouth the pleco a few times and then leave him alone?
Thanks in advanced for anyone's experience with this!

Hoping to buy some extra larger size Yellow Chubby Plecos and L397!
Thanks
