Help confirming gender.

Hi,

Could anyone confirm if these two are male and female or both the same sex.



Cheers

both Females.

Any chance the fish on the right is Male? The head shape is a bit wider but I think I am kidding myself.

Thanks

hehe, certainly look like both are females to me.

I agree, looks like two females, almost certainly.

Even if they are opposite sexes, I would not try to breed these two together: The size of the spots are clearly different, and even if they are the same species [plausible], they definitely aren't the same regional variant [unless someone can confirm that they really are living together and spot size is just a natural variation]. The one to the right is Panaque albomaculatus, the one on the left looks like a very recent L-number [from memory L437, but I could have that wrong - there is a very recent thread on the similarity/difference between these two in this forum].

Hi Mats,

..I believe you are referring to Panaqolus sp. "L 426" (or Panaque, if you wish).
However, I´ll have to disagree with that identification: to me those two look like Hypancistrus, something from the H. contradens/L201 group of species/varieties. That does not affect the righteous advice to keep them separate, of course!

i would say both are female but because of head shape, it could just be a very fat unfit male-which i highly doubt. what species are these?

Have you got pictures of sexual papilla?

I'll try to get a bottom view this weekend. They are hypancistrus.

But either way, it is not a "pair" suitable for breeding - they are two different species!
