No, but there really should be ... In its place I have a "spreadsheet of shame" that I use to filter out any undesirable sequences before I use them. Problem is it needs manually updating and that takes work :( Some of my favourites are: Solea solea identified as Xiphias gladius Thunnus id...

I don't mind them publishing papers that nobody will read, but when put this crappy data on public databases, it really bothers me. This one , apparently "Tatia intermedia", is actually a goldfish! See https://blast.ncbi.nlm.nih.gov/Blast.cgi?PAGE=Nucleotides&PROGRAM=blastn&QUERY=M...

Making phylogenetic assumptions based on a small amount of data can likewise be very misleading. With a small amount of data those incorrect relationships tend not to be well supported, and so the gut feeling is that with more data they will be resolved. They often are resolved with 100% support .....

It's increasingly common now to use entire genomes for phylogenetic reconstructions. But what always staggers me is how well the crappy old methods can still perform. Take the recent loricariid phylogeny by Roxo et al. (2019) using 328,330 bp of ultraconserved element DNA ... I get much the same top...

Aren't the specimens ID'd as A. aguaboensis problematic also?

Haha, yes.

In short, it maybe is time to re-introduce "Ancistrus sp(3)" Remember this thread ? Sadly very few additional Ancistrus DNA barcodes have been publicly uploaded since 2012, but I ran the analysis again to see if anything has changed. We do now have some trade samples from both South Afric...

Why publish one paper when you can publish ten?! Just gaming the system, unfortunately, and not adding much value.

I was wondering if I could find the nationality of Mr. Wertheimer as it could be a hard v or a soft w depending on this. From Etyfish : "... belonging to: Mr. Wertheimer, who collected type, either Louis Wertheimer of the Thayer Expedition to Brazil, or Achilles Wertheimer, who died on the exp...

Oops, my bad. No idea where 2017 came from. That's the paper (2013).

"They" being costatus? Yes, P. costatus . Think the DNA looks different in these two spp. I will consult Mols book when I get home. I think this fellow could have it's own species entry... Ah ... there's indeed a Platydoras sp. "Maroni" (=Marowijne) in Arce et al. (2017).

They have been recorded up to 10.7" SL (Pioski et al., 2008), and that was based on a very small number of specimens, so I'm sure they get bigger.

Vendors rarely use SL as far as I know, so the sizes offered definitely fit the species.

Wow ... starting to look like mini Pseudolithoxus now!

A friend had exactly the same thing with a sparkling gourami the other day. This one was being bullied, and then after being isolated it stopped eating and got malnourished.

I think it's just a generic symptom that could be caused by a number of things.

I caught these guys in the wild, and they didn't live in particularly fast flowing water (just a regular lowland stream). What's the rationale here?

Most I've kept appear to like a bit of current though.

Looks like a case of velvet, I'm afraid.

Plecos such as these won't suck on the glass during middle of the day unless there's a problem.

What temp is the tank?

As as well what stuby already said, they have a very different head shape. Look at the position of the eyes in particular. Ancistrus dolichopterus (L181) has eyes located very much on the side of head, vs more on the top in L213. L213 Screenshot from 2019-03-11 10-41-23.png L181 Screenshot from 2019...

It sounds like these might be something I throw in with the white clouds and choprae, along with an extra power head.

Powerheads can actually reduce oxygen because they can increase water temp by some degrees, negating the benefit from the movement.

Airstones are better.

In my experience otos---the common types in stores, usually Otocinclus vittatus or Otocinclus vestitus ---do well if you do the following things: (1) Buy otos that have been in the shop for a while and are healthy and actively foraging. (2) Give them warm water (~27C). (3) Make sure they have enough...

Swimming in mid-water upside down is also a clue to look out for.

Fish here in Europe are good only for food !

Absolutely not true. Bulgaria has some stunning species, particularly loaches like Sabanejewia and Cobitis. Perfect for a mini biotope project. Who would not want to keep this fish?

Yes, definitely . Looks like a reasonable ID.

Maybe lets talk about something less divisive, maybe gun control or Brexit? :-p I think kvnbyl illustrates a point that morals/ethics are a constantly shifting continuum, and every person will draw their own blurred lines somewhere. Personally, I support the sustainable trade in wild fish because it...

i can think of some reasons, they are more attractive has to be at the top. they are cheaper to produce, they handle shipping better, they are more disease resistant. Well the attractiveness is subjective of course. Being cheaper to produce I knew about (breeding with a female of high fecundity), b...

If I remember rightly the population above the rapids at São Luis are prettier and command a higher price than those captured downstream from around Itaituba.

if it gets more people to keep fish and there is a natural supply of the original species for people who want the pure form what's the harm? But there isn't really a supply any more. Hybrid Synodontis are in every pet store I go to, but the wild types are extremely hard to find these days. I rememb...
