Do they all have a blunt, short snout? It may be a photographic optical illusion, but in your first photo, the front-most fish in the bag appears to have a longer snout.

Cheers, Eric

Congratulations on the spawn!

This isn't a report of a CLOG data issue, but more a question about how part of the CLOG works: When reading the Registered Keepers of any particular species, there are five pieces of information presented. A hypothetical entry might look like this: (14) bekateen (p: 2, k: 5), who also notes: "...

I don't know if it's just me, but I can't view your video, Ted. I receive the error message, "An error occurred. Please try again later" when I click on the link. Let's see if this helps:

@MatsP, from the H. guahiborum CLOG, you have reported owning more of these pretty fish than anyone else. What is your experience with them, in general and especially with regard to the questions above?

Thanks, Eric

Ok, thanks Racoll and Johannes. ... So @Racoll, what does cucha mean? No idea. Fishermen in these places can make up many silly/strange/nonsensical names for fishes. For example, L066 and L260 are called "bread" in Brazil. No idea why. Because they are common perhaps? You inspired me to go...

Okay, thank you.

... So @Racoll, what does cucha mean?

And do you have any perspective to offer on the observation that these plecos live at 88F? Will Centomochlus perugiae like it that hot, or even close to that (e.g., even 85F)?

Cheers, Eric

Alas, my coworker who is Brazilian and who speaks fluent Portuguese is out of town for the week and unavailable to ask. Maybe a Spanish speaker would be better ;) See? That's why you're paid the big bucks! =)) Actually, the translations "doghouse," "kennel," and "listening&...

If you just got the tank last night, remember everything you went through in the beginning about starting the nitrogen cycle. Newly setup tanks are very dangerous. If you have any gravel or sand in the old container, transfer that into the new tank without washing it. And move over the old filter sy...

I'm certainly no student of South American languages, but L106 is named after the Guahibo tribe. Some of the indigenous people in this area (e.g. the Yanomami) traditionally live in a very distinctive type of circular fort-village. Perhaps the Guahibo tribe is named after the type of house they liv...

Sure, I can do that.

... Still, the main problem is: when people posts pictures as a reference, it's usually plecos in very good shape and condition and with obvious sexual dimorphism... Best thing would be making detailed shots of plecos in bad condition or youngsters and update those in intervals of like 2 months. So...

I may have answered a couple of my own questions (and importantly, question #2 in blue). I came across the following article: Ajiaco-Martínez, R.E., Ramírez-Gil, H., & Arias -Castellanos, J.A. 2012. Fisheries aspects and reproductive biology of Hemiancistrus guahiborum , in a scree in the Bita r...

...looking back at the first page of this thread and the pictures you posted, I noticed something even more obvious when looking at the vents from the side.... Male - no Vent visible form the side Female - Vent clearly visible from the side If you re-watch the first page you will notice that this s...

Thanks for the compliment Johannes. You're right, the female vent is so big in my females that it's visible from the side in all three females' photos. I hadn't noticed that before. What you may or may not realize from the ventral photos of these females is that their genital papillae looked like wa...

Regarding new aquarium shopping, it never hurts to ask the management. You might try two approaches: (1) Go to your LFS (not a chain like Petco/PetSmart) and remind him of what you've been doing all this time, then see if they would offer you any special pricing. Or (2) Go to PetSmart and try the sa...

Okay, as a follow up to this thread ( Re: What is a good tankmate for Centromochlus perugiae? ), I've been waiting a couple of weeks for my LFS to restock their Hemiancistrus guahiborum . According to the store owner, a shipment of new fish is expected to arrive in the next 1-3 weeks. In the meantim...

They are so cute! Enjoy them, and good luck with them.

Cheers, Eric

Hi Johannes, That is a very nice looking male. In my opinion, don't worry about the appearance of the pectoral fins (if your concern is that they look kind of "wing-like," similar to the pectorals on some banjo cats). I noticed that when I photographed my males and females in air, their pe...

It was the challenge of sexing that led me to end up with 7 clowns, instead of 3-5. I suspected that my first was a big female. The next two I bought were too young to sex confidently, but I tried to pick 1 M and 1 F. If you read my thread about sexing clown plecos (http://www.planetcatfish.com/foru...

Thanks coelacanth. That fits with my experience. Maybe I should get rid of these guys, or at least move them to another tank.

Cheers, Eric

Would it be possible to start with one or two and add the others (a few days) later or is it better to introduce the whole group to the aquarium at once to avoid territorial issues? In my experience, territoriality when more are added later is not a problem IF you do it in this order: Remove the re...

Interesting technique. How do you use the swearing? And do you swear better with two nets than one?

Cheers

P.S., on a more sincere note, congrats, and you have some cute little eggs on that leaf.

You're welcome. And yes, I too thought they did they nice job.

Cheers, Eric

I also think that this looks like pre-spawning behaviour rather than fighting. Given that it's the males that do the brood care it is not that surprising maybe that they can be choosy when it comes to females. I agree with your point that male mate choice could very likely be occurring here. I supp...

Last but not least evidence for this being a female: right after the "fighting" they were spawning :D right? Yes, indeed. And that is what tipped me off to go back and review the video, where I then noticed the genital papilla. I realize in hindsight that it may be very obvious that this ...

For plecos, I am sure to lay some pieces of slate on top the sand to sit the pleco caves on so they don't become buried in the sand. Good advice. In a similar fashion, in my tank I placed a rounded river stone underneath the each cave at its opening, so that the cave sticks up slightly into the wat...

Very clever creating different levels with caves like this Hi MarlonnekeW, Thanks. Yeah, I liked it too when I set it up. But I have to admit that the fish may not think likewise :)) ... So far NONE of the adult clowns has taken up residence in any of the higher caves. I've seen other people's tank...
