help with sexing L34?

I was sold these L34 as a pair, but wanted a second opinion on their sex?

so do you guys think i have a pair?

sorry couldn't find much info on gender difference other than males have more bristle which doesn't help much since females for l34 have bristles as well.

Below are links with pics, if anyone could help distinguish the genders.

I'd say you have a pair there. Not having these fish available in Aus we are not too familiar with them. I certainly dont discuss them in my book but Kathy Jenkins has a good bit of info on them in her book. Also a good read.

According to the Prophet, Ingo Seidel: "The tencacles of the male are very thick and not branched at the end".
