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...

Looks promising ... fingers crossed!

Regular aquarium dechlorinator will also remove any bleach traces, for extra peace of mind.

The thing is, genetics is a message in four letters, ACTG. A can switch into T and back and C into G and back. A to C happens a lot less, and the other way around. But when I compare 2 species, 1 has A and the other T - I don't see how many A-T-A-T switches have been made. Morphology does not have ...

Yeah, these are very much observations I have made too. But having chatted to some store staff, I can also see it from their side. They order in a box or a large number of species x, but sometimes they just don't look as great as they were expecting from pictures. Now they are lumped with dozens of ...

A few of those images in Figure 1 look very familiar indeed ...

Great video!

Generally with most loricariids, as they grow, the spots get smaller and bars break up into loose spots.

This fish looks quite big, but the scale is not that clear.

I'd agree with Jools. or something very similar.

For the time being at least, they (L071/L181/L 249/L183) should all belong to the same species: Ancistrus dolichopterus . Ancistrus dolichopterus , as described, can have either 8 or 9 branched (soft) rays in the dorsal fin. As stated, most other Ancistrus have 7. There is variation, for sure, so po...

I keep my water levels low because it allows the plants to emerge, and also stops the fish getting out. Not nice finding them all crispy on the floor in the morning.
