Before getting into the graphs, here's what the lead author of the paper told me about why they did not list sexual dimorphism in the paper. Basically, he said that since the researchers didn't open the abdomens of the fish to inspect the gonads (for testes vs ovaries), they didn't want to infer the ...

Quick update, the outlier with the (relatively) long narrow head was one of the smallest fish captured. Graph to follow.

If the authors had recorded collection method, it would have helped understanding that. From the paper, the authors wrote this: Morphometric data from type material were taken from recently collected specimens by the authors that are deposited in the fish collection of Museu Paraense Emilio Goeldi ...

I contacted the lead author. He contributed the photo we have and he explained why the team didn't discuss sexual dimorphism. I'll have to add that later, as I'm traveling now. He also sent me the complete data table (with SL values) for the paratypes, so later I'll analyze that and see what pops ...

Just a thought on how you find two specimens being different from the remaining cluster of paratypes; I don't suppose they may actually have included both Peckoltia sp. L80 and this Hypancistrus in their material without noticing the difference? Surely that can't be? -Haakon They provided another ...

Maybe a new genus is in order?

Looking back at the original DATZ photo (HERE), I'm wondering if the first was a Peckoltia or if it was . The solitary photo in that article shows a rather long maxillary barbel, so I'm guessing the true L080 is a Peckoltia, not a Hypancistrus.

There's no way this new species is the same as the fish we show here on PCF as Peckoltia sp(L080) . Compare the mature male L080 shown in our CLOG page to the holotype of Hypancistrus parkateje (which appears to be a mature male) from the paper - They have totally different sexual dimorphisms ...

Thanks! I also see this thread with info: "Lamontichthys sp. Colombia"

Hi All, Yesterday, I traded in 145 Auchenipterichthys coracoideus and about 20 Ancistrus sp`Rio_Ucayali` at a local wholesaler. They had a tank full of 7 smallish (~6-7 cm SL) Lamontichthys llanero . I deliberated about all the reasons I SHOULDN'T get them but in the end I did. They appear healthy ...

Did they announce a location and/or date for the next CatCon? I've heard rumor, but I'd rather not repeat it in case it's false.

I'm not sure Onions ( Allium cepa ) will work, they are plants that grow best in dry conditions. I'm using green onions (scallions), Allium fistulosum . I don't know them well enough to know if they should fare any better than regular yellow onions in this setting, but there are videos and websites ...

Thanks for adding this. That makes sense.

Weird update to this: I tried again today to edit Chaetostoma breve and the function still didn't work. Then I renamed the page to Rineloricaria atratoensis and re-tried the edit page function, and this time it worked. I was able to delete the Chaetostoma info and add the appropriate R. atratoensis ...

Hi all, That is looking very promising. I like the Ginger. Another culinary item you could try would be Lemon Grass ( Cymbopogon citratus ). It will grow from the stems you buy in the supermarket etc. (as long as they have a small amount of rhizome left at the leaf base). cheers Darrel Hi Darrel ...

Here's an update on the tank: This tank has now been running approximately four months. Some of the plants I added (green onions, cucumber, cherry tomato, and catnip) thrived at first (each for about a month), then died back. Other plants (Monstera, ginger, African iris, bearded iris, calla lily ...

Hi Jools,

For about a week I've been trying to access the Edit species page to clear old data from . The link never loads. I've also tested the link on other pages, getting the same failure to load.

By contrast, the rename species link loads just give.

Cheers, Eric

They might be male and female, but I think you might have two males, based on the pectoral spine odontodes.

Cheers, Eric

Hi AnnieH, Welcome to PlanetCatfish! As for your squeakers, are they Synodontis eupterus ? How large are your fish? Are they about the same size, or is one notably larger than the other? How big is your aquarium and how is it decorated? Do you have lots of hiding places for the fish? What other fish ...

They look like L333 to me, although I wouldn't consider myself an authority. Do you have any info on their source?

Cheers, Eric

Awesome sauce! Congratulations!

Agreed, thanks for sharing.
