What are these 3 Ancistrus?

All from the Rio Madre de Dios system in Southern Peru, any ideas? If not, I'm just going to put them online as Ancistrus sp. but I thought I'd ask here first?

Hmmm, that last picture reminds me of the pair of fish I bought as L89. The fish that I have still looks very much like the juvenile picture in the CatElog, although it's easily over 3" SL. I'll try to get some pictures of the male and female both, this evening. My fish should have come out of Brazil, but I don't have information on where.

The last two appear to be L089, as Barbie said. But the first one is an ancistrus I have never seen.

The Cat-eLog on L89 says that it's in "Manaus, Brazil", which I take to be either:
here (The moer likely option)
or here.

Madre De Dios in southern peru is not near either of those places, and I would even go as far as saying that there's no continuous waterway from one to the other.

[Apparently, south america is littered with placenames that are either similar or "the same", so it can be difficult to tell which place is meant by just a name of a place, river, etc, but a tie-in with some state/county/region is always helpfull.]

So although the fish LOOKS like L89, it's probably not...

The first one is a real beauty, isn't it? Where can I buy one?

Btw, I hope I didn't offend anyone by checking this up and pointing out the vast distance between the supposed catching places of these two fish.

I have no problem with it at all, that's why I noted where mine came from, actually ;). I spent quite a bit of time looking at the picture and doing some background searching on L89 first. They may not be collected in anywhere near the same water, but the fish itself really does look nearly identical. I'll try to get some pictures of the 2 I have, later, as I said in the first post.

Madre de Dios is also the main river shared between Peru and Bolivia that flows into Rio Beni that in turn flows into Rio Mamoré that are one of the tributary's of Rio Madeira that is the biggest tributary to Rio Amazonas, but that is a looong way :wink:

Between, it seams to be more blue eyed plec then we knows about...an Ancistrus with that colour of the eyes could be a hit in the trade.

The fish of the third pic it's very similar to this Ancistrus, I buy it as Ancistrus sp. "Maranhao" and probably came from Brasil.

Image

The Ancistrus in the first pic, I´ve seen them beside to this. The fish of my pic weighs around 10cm, but the juvenile fish, around 4 cm, they're equal to the first pic. But the fish I've see, came from Colombia or Venezuela

We have the first species in Australia. We call it orange spot bristlenose. And yes we have no idea what it is either?????

We thought it was a hybrid.....

The above red spot <i>Ancistrus</i> is L110 I think. The picture I posted is a juvenile colouration and it may well lose that colour. I collected one specimen very similar to this in Amazonian peru; I suspect it changes appearance with age. L110 keeps the red spots but they get smaller like the picture above.

BTW, it would be nice to use the two above pictures in the Cat-eLog...

BTW, there is a danger here that we can't ID them becuase we restrict them to the drainage they're found in. I mean, we're coming up with very similar fish from elsewhere. I was of the same view with the first picture (the orange barred species) which i though was VERY close to L59.

Yes the main problem is L59 is coming from the Rio Puraqequarama near Ourém, so close to the mouth of the Amazon river... basically totally opposite from these, there very little chance that these 2 belongs to the same "species"...

So unless proven opposite, I would considered these as 2 seperate "species", with the Peruvian Ancistrus having no L-number know so far... also there is little Ancistrus species coming from Peru having a L-number, and the ones that have do not look similar to any species shown here...

cheers

I have received several shipments of "Ancistrus sp. mixed Peru" during the last couple of years. In every shipment there are a few specimens of the first depicted Ancistrus. All the specimens I have received have been about 5 cm (2"), and in quite poor condition. I don't know which exporter in Peru they come from, as I get them from dealers in Sweden and Denmark. Nonetheless it's a very striking Ancistrus, and apparently it's not extremely rare either.

Woops, glad you resurrected this thread! I ran down and took a few pictures, but only this one came out. I'm going to have to pull them from the tank to get anything better I think!

This thread popped up to the top of the time heap this morning because a spammer replied to it overnight.

I've removed the spammer and the spam, but now I'm curious about the photos that were in the OP by @Jools. The photos have a planetcatfish URL in a folder called temp. But I don't believe we still use that file structure anymore, since the photo links are all broken.

Jools, are the photos still around? Did they get incorporated into CLOG pages?

Cheers,
Eric

I don't know for sure, I don't have a record of that from 2005. They were from Lance Peck at Go Wild Peru, before it was sold on I think. These will now likely be the ones in the L393 page. And if they were different spp., then maybe one or two of the L5xx Ancistrus sp. from that area.
