The "secret" to identifying the L204, as I undertand it, is to look for a hairbrush like appearance from mid-section back to the tail. This will not appear on sexually immature fish and you may think you have a tank full of females...or at least that's what happened to me:
I isolated a male and two females and gave them a one month dry season. During that time, the male stayed in his cave continously. The 2 females fought and chased each other regularly (3 months ago I lost fish to this activity...."swim-by stabbings" with the pectoral fins. Corpses had puncture wounds!)
One day, while all was quiet, I noticed that the 2 females had become decidely male looking. The hairbrush appearance seems to have "stuck" to all three fish now.
Did the females (which were never females to begin with) COME OF AGE during the dry season?
I don't know. I'd love to hear some opinions. Actually I'd love to hear from someone who's vented both sexes of the L204.

BTW: These fish I've mentioned were over 4 years old. I do not believe the fish PANDADOSMARES posted are old enough to reliably sex.
they are pretty young yet, but as i said, i was following Ulrich Glaser descryption on how to identify both sex on pekoltias and panaqolus who said that can be done at a size of 4 cm, the ones i have long pass the mark of 4
The problem is now im not so sure of what they are.
Kevin,
You will find a review and photo of the book in question in the "Books" section at the top of the screen.

I kind of feel like I'm on a scavenger hunt here, but I think I understand now that Pandadosmares read some text by Glaser on sexing Loricaridae in the "The Most Beautiful L-Numbers" AQUALOG?
(I truly didn't understand that part)
I have the first soft cover "All L-Numbers" and the new Hardcover and Glaser isn't an author for either one...oh well, never mind, I've made a MUCH BIGGER DEAL of this than it warrants.
My apologies to those who've read this looking for real info!
Sincerely I wouldn't base my sexing identification on what was written in the book "The most beautiful L-number"... some stuffs written in there are so...( I have no idea what word to use to express my true feeling toward this)... certainly one of my worst book purchase, hopefully it wasn't so expensive...
Anyway... L204 isn't sexable until he is at least 10cm/4in long...
Sorry to show my L204 again but on this pic. you can se the spines/hairs, mentioned earlyer by Kevin, on the back of the fish.
Just delete the pic's if to spacy..

Why do we put so much time and effort into trying to determine the sex of these catfish!
I don't think i have ever heard of a reported spawing of a panaqolus species YET.
Sorry to put a downer on the subject.
Has anyone had any luck or read this on the web anywhere?

Sorry to know you think that way probably its best for you to go and play whit "lego" instead of trying to breed catfish.
Whats the point of of doing anyting then
If you search the forum theres been succesfull reports of breeding L204, but not much info about what to do.
Pandadosmares, Yes, both sexes get the caudal fin extensions but only the male develops the "hairbrush" with maturity. I have now had, killed, or currently house a total of 12 of these fish of sexable age and am only now hesitatingly sure I have one female. Recently, I thought I had only one male!
I have set them up with multiple caves in both vertical and horizontal positions and will begin a one month dry season this weekend...and see who gets fiesty and who gets friendly.

Interests: breeding catfish from all parts of the world and getting them into the hobby. favorite catfish is the stonecat madtom,btw ingo how are my fish
am i mistaking, but i believe Larry Vires has these spawning now. i could be wrong but i thought i saw him talking about it in aquabid chat. i'll try to find out and pass the information along.
I do have 3 adults atm, easily 4-5"+, want me to post pics so someone can point out the differences? I am horrible myself at sexing these, so would not know where to start.
