Ladies or gentlemen?

Post by Warrior »

Dear catfish friends,

Last monday i happened to get my hands on an extra L260 for my community tank and an L134. I'm thinking both are female...what do you guys think:

L260:

L134: (sorry for blurry pictures..)

The L260 is aproximately 8cm while the L134 is just about 4-5cm. If needed, i do have some other pictures from the sides.

Thanks for your help guys!

If you were to put a gun to my head and told me the only way to survive is if I would sex these fish I would say The L260 was female and the L134 might be a male.

I'd say that the best thing to do is to keep the fish for a while and see how they develop - at least with the Peckoltia, I can guarantee that a male will show it's male-ness in a month or two (unless it's very small).

Btw, I don't see anything to DISAGREE with Waldo's suggestons - but the Peckoltia I wouldn't say becuase the pictures aren't clear enough to really tell...

Gun... MIGHT... male :)

I'm just going off of Barbie's method of the pectoral fins.

Matt's right though. Take more pictures. Practice makes perfect.

Hi!!

The QA is a male, not only the pectoral but on the first picture you can see a rather long interopercular odontodes

Regarding L134, no idea, pictures aren't good enough

Cheers

Yann, can you explain to me what a pectoral is (or where it is) and what interopercular odontes are???

I assumed this was a girl because of the wider and rounder bodyshape.. :(

This is my best picture of the L134. It is about 4-6cm long now.

4-6 cm is too small to be sexually mature, if that's the entire fish (TL). 6cm SL (nose to just where the "meaty" part becomes tail-fin) would probably be about right for sexually maturity.

Seems to have a decent set of opercular odontodes on the picture tho', so I would guess male - but the picture isn't very clear, and it's not a definite. Let it grow a bit and see what happens.
