These were also collected in the same blackwater habitat as the Hypoptopomatinae. These are some big
Ancistrus. Color immediately after collection was very black with white spots.

Hi
Really nice monster...
Did you managed to catch females as well?
Would be interesting in giving a try at breeding these guys... I wonder how many eggs could contain a single spawn.... the kind of species that turn you tank into overcrowded in one spawn...
It has a rather high body compare to other species.
Any idea if it is already descirbed and what would be its name?
Cheers
Yann

Ancistrus shanelinderi ;)

Sadly no females but I have my people in Leticia looking for some. I agree that these things should put out a few hundred fry per spawn with ease. If I get my hands on a female I'll certainly try my best. No
Ancistrus sp. that I can find has been described from that area. I am surprised that it does not even have an L Number.
Thanks for the name suggestion

Janne,
L 150 comes from the upper Orinoco near Puerto Ayacucho. Different river system altogether. Also, notice, as Yann pointed out, how deep the body is. The fish's head is over one inch (2.4cm) thick. Any other ideas?

Shane that looks VERY much like the big male starlight bristlenose I had a few years ago. He was 7-8 inches SL when I got him, and didn't grow in the 3 years I owned him. I had 2 females for him, but I lost him about the time one finally started to fill with eggs. The hazards of moving around too much I suppose. I never did find out his collection location though. He was a very neat guy.
Mine was a rich chocolate brown with cream/gold colored spots, and a tiny bit of light tips on his finnage, but no reddish leading fin rays or anything. Yours definitely looks awesome

I'm not 100% sure that mine are L-150, I got them from a shipment out from Colombia and they was around 6-7" (15-17 cm) TL and the color of the male was black with light spots and the female was more brownish exactly like your picture of the male.
My pics dont really show how big they are but the head is very big for an ancistrus species and when they spawn they give between 350-400 eggs and fry each time.
There are several of them that look very similar so it's not easy to know what species it's, are you sure there not are any conection between this river system ;)...

Janne,
How did you determine that they were L 150? If they were shipped from Colombia they could have shipped from Leticia (making it a good chance that we have the same fish) or from Puerto Carreño on the Orinoco making it a good chance they are L 150. There are three main collection points here. Villavicencio in the llanos shipping Ancistrus triradiatus, the llanos Corydoras, and Rineloricaria. Puerto Carreño on the Orinoco shipping the L 120s, L 200s, etc and Leticia shipping mainly tetras, angels, discus, doradids and Amazon Corydoras.
Do you have a close up pick of your male? Yes the two rivers are connected for part of the wet season when the upper Orinoco bleeds into the upper Rio Negro. A few spp. are shared between these two systems but not many make it past the Rio Negro since at Manaus it connects to whitewater in the main Amazon channel. The major exceptions being the large pims that live in white and black waters and are found in both the Amazon and Orinoco systems.
One key characteristic I noted is a large black spot between the first and second rays of the dorsal.
Barbie, there is a good chance that this fish was exported from Leticia at one point or another so it is possible that you had them in the past.

They was listed as L-183 from the exporter that was Romeiro something...I dont remember the exact name of the company, I have search for a long time to find what species they are but the closest match is the L-150. I know they are exported from Colombia but did'nt know which river...but they prefer a little cooler water around 24-25 C and the fry have a much higher surviving rate at a lower temp, maybe that is a clue.
I dont have a really good picture of my male but this show him in the real color, and yes he has a black spot between the first and second rays in his dorsal very near the body.

Hi,
I have some that looks a lot like yours and Jannes.
One key characteristic I noted is a large black spot between the first and second rays of the dorsal.
Mine also have these.
But so does L182 (or Ancistrus Punctatus or both!?) - see:

It's impossible to determine this kind of fish only with pictures
