I promised, a long time ago, to get a shot of my male Clown Pleco. The little fish finally co-operated in coming out to eat while I had the camera nearby.
Jools: if you want me to mail you the photo, just let me know, as I don't think there's a good shot showing the male read body odontodes in the Cat-eLog...

Hi Mats!
I've got another pic of the odontodes:
Dorsal view:
I think it's interesting that the odontodes even goes up to the head!

I didn't realize just how furry they got! Does anybody know the purpose of the fur?
I'm just curious.

Hi Jonas!
Some news with your Panaqolus?
@Amanda:
They only got the furry in the winter, when it's very cold!
No, just a joke, i think it's a protection so that no other fish could come to the eggs/frys.

If it increases the chances of reproductive success (increased fitness), it will be favored by evolution.
The male fish can be stuck defending the nest for three weeks or more. It makes perfect sense that these heavy odontodes would be favored by evolution.
1. They make the fish much less appetizing for a potential predator. They'd be fairly easy prey for larger fish otherwise.
2. They also increase the ability of the male fish to defend the nest from smaller egg-robbing fish.
3. Aid in defense to prevent other Loricariids from usurping the nest site.
4. May also be favored by mate-choice. Females by choosing males with heavy odontode growth may also play a role in the further evolution of this feature.

Paul,
I had a Homer Simpson "Doh" moment when I first posted the question(maybe to keep them warm?). Then I thought about it for a moment. These aren't mammals! All the "L" numbered creatures I observe growing fur are egg-sitters and the males grow much more fur than the females. Thanks for the extended response.
Lovely photos Tobi! How often do they breed?

Hi Amanda!
I've got these catfish since end of august '05, they spawned the first time one month later, the same male spawned with another female one month later again. Three weeks after that another male spawned with the female form the first spawn, so you can say they spawn every 4 weeks!

Similar to Tobi's, mine is about 7cm (3") total length. Not very big, the females are longer and wider.
