Unfortunately my conductivity and temp meter packed up on me; batteries ran out unexpectedly. What I did measure was that the water surface of the slower moving lower Tapajós was 33C (also very soft, only 20 us or so). Upstream where the plecos were caught, the water ran faster, and it was also colder down a few metres near the bottom. I estimated the temp to be upper twenties. For the aquarium, I'd say about 28-30C is about right.

As far as I know, this is the only type fish from the Tapajós, and was the only one we found near Itaituba. If your fish look the same as this, and they really did come from Itaituba, then I would call them .
Narwhal72 wrote:Did you see a lot of variation in the L140 type fish?
Yes, but the distinctive thing about them was the very yellow colouration, but unfortunately the ones I photographed were a bit washed out. Here's another below. Look at the colour of the mouth. Also the banding will tend to get narrower as the fish gets older, I think.

As you know photography in the field is difficult and very time consuming. I couldn't photograph everything, so I prioritised the catfishes. Here's a few more pics. Let me know if there's anything in particular you are interested in.

Along with the , both of these guys were caught hiding among mats of floating grasses in shallow water (as pictured earlier). Water was really warm here, maybe 35C.

The water was very warm here, over 33C where the Peckoltia L140 were found.
DSC08387.JPG

The holes the Peckoltia L140 were residing in. The "rock" was very soft here, more like hard mud, so I think they actually dug the holes themselves. They were about 2" wide and up to 12" deep.

Last sampling site, the city of Santarém, right at the mouth of the Tapajós. We collected these fishes under a pier at a boatyard in the city, very close to where this photo was taken, just round the corner to the right in fact.

A discus. Also under the pier!

I think. Not sure where it came from. It was a gift from the fishermen, and I forgot to ask.

Thank you so much for sharing these wonderful photos, not only of the fish but of their natural surroundings as well! Great timing on your part as this is exactly what I've been looking for recently - very useful for my upcoming aquarium project, and I'm sure many others' too. Do feel free to post up any more you have, I'm sure we're all enjoying them :-BD

Great great stuff! Thanks for the temperature readings, really appreciate it. Was surprisingly high to me but I guess it's in the height of the dry season now.

Thanks again some great pictures and lots of information.

Sad question but any idea if that mud like rock can be bought? Sorry just thinking allot of cat fish if they cant find a suitable spot make one perhaps others would dig holes in it and make suitable breeding spots.

The Centromochlus sure looks a lot like C. concolor.
As far as I know, this species has not been found yet in the Rio Tapajos, though.

Nice idea, but don't think it would work. It would make a horrible mess of the tank, as the water would go very cloudy for sure.

kruseman wrote:The Centromochlus sure looks a lot like C. concolor.
Yes, they are similar indeed. Will have to check in more detail.

Marc van Arc wrote:Ageneiosus Looks a lot like A. marmoratus, but the paleness of this fish.....
It was pale because it was very dead and starting to go bad. I don't think it looked like that in life.

Marc van Arc wrote:Given the fact that it lacks an adipose, this should be Trachelyopterus coriaceus
Nice one. Thanks. I was struggling to work out what that one was.

It's not, some people rather exaggerate this point and have created this misconception.
