Thanks for sharing your videos, based off the second... it's pretty easy to tell the difference huh? lol

Last 2.

I put 1,2,3 in a different tank from 4,5 since I'm not sure if they are really 340(purchased from a different store)

Hey all, my L340 are now almost fully grown and I was wondering if anyone could sex em for me.

I think I have 5 males, but #2 might be a female, not really sure, only going off her size.

Thanks!!!

I'm 95% sure it is a female, too fat to be a male for one. Also, my super red female has bristles all around her "chin" too.

I have 6 L340 Mega Clown Plecos, I would like to try and breed them, but I am concerned I have all males 0.0

Any help would be greatly appreciated. I think there MIGHT be 2 females, but they are still pretty thin.

The fish are 2.5"+

Thank you so much! I never would have thought of being able to ID them this way, I am going to make another trip to my LFS to check them out from above!

Added a reply to show more pictures.

I was at a LFS today and was curious what fish these might be, they are labelled L129, but I thought they might be L340. Also, can anyone ID my current stock if they are L340 or L129, I purchased them as L340. One of the fish is very faded and has some fin damage, only have had it for a week now ...
