Could this be Ancistrus sp. Rio Ucayali?

I have a very pale sand substrate, sort of like a broken white. Although in hindsight, I think regular pale brown sand would make the albino's pop out more than they do in my tank atm. Then both the albinos and blacks would really jump out at you I think.

Because it looks like one to me and it's the most common Otocinclus in the hobby

Most likely Otocinclus vittatus

I was thinking Hypancistrus contradens

I actually have albino aeneus and black schultzei in my community tank, and it is pretty neat

The pattern looks like corydoras schwartzi to me but it's so dark...

I'd say L114

I was wondering about the genetics of colour mophs found in BN's. I know of these morphs: albino, red, calico & piebald (look very similar to me, if anyone can explain the difference please do), amelanistic (l144) and veiltail . I'm going to assume most of these are recessive but if anybody could ...

The little one looks like Nigrolineatus to me (I'm no expert), but I'm sure Jools can tell what it is with a lot more certainty

I haven't seen pygmy cories with this exact coloration or orange on the fins, but they are variable in appearance. It depends on where they were caught in the wild. Certain population can have a slightly different appearence than the norm, but that doesn't make them a seperate species. Anyway that's ...

Those look like pygmy cories to me, albeit a bit darker than most.

Jools, could the top specimen maybe be Pseudacanthicus Serratus? I saw a preserved specimen in the Aquarium Museum in Liège, Belgium that looked similar to the one in the top photo. Atleast the spines along the body appear very similar to me

Maybe a juvenile Pterygoplichthys gibbiceps?

@pleconut Damn I think I would have lost my composure with that collegue if I were in your place! Your patience is almost infinite it seems like.

The glass catfishes are schooling fish. The most common one here in Belgium is Kryptopterus vitreolus

Maybe a it was just another species of hypancistrus other than L411?

Maybe they actually bred and produced eggs but that doesn't mean the egss are viable. Besides claims, were there pictures of fry too?

I think this might be a brochis species, but not sure though. Also, maybe she is gravid? Then again I haven't seen one with such a huge belly.

Wow! Maybe some we can see some more mesmerizing photos when the eggs hatch?

It might be a Corydoras CW096 or CW097

It's definitely not a corydoras metae

Judging from the shape of the snout I would say Silurus seems to be right. Take in mind I'm not an expert though, unlike some of the other members.

I got 6 corydoras pygmaeus

I thought I'd share this video. I've never seen or even heard about this mutation before and I'd thought some of you would like this.

Thanks for the info kamas!

They were sold to me as 'black venezuela' and I was told that it wasn't sure if it was a new species or a colour mutation of an already known one. I was hoping somebody here could give me some more insight on this.

Thanks in advance!
