Re: Rio Tapajós
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.backstreetgambler wrote:could you post any water parameters? I would be particularly interested in the water temp
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:Are you very sure about the ID of the fish in the picture as L140?
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.Narwhal72 wrote:Did you see a lot of variation in the L140 type fish?

Re: Rio Tapajós
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.Silurus wrote:I'd be interested to see what kind of non-catfish you've been catching.

Re: Rio Tapajós
? Only got one of these. Appears rare.
. Found quite a few of these. Relatively easy to collect.
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.

Re: Rio Tapajós
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.

Re: Rio Tapajós
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.

Re: Rio Tapajós
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

Re: Rio Tapajós
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.

Re: Rio Tapajós
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.

Re: Rio Tapajós
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.

Re: Rio Tapajós
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.JamesFish wrote: Sad question but any idea if that mud like rock can be bought?
Yes, they are similar indeed. Will have to check in more detail.kruseman wrote:The Centromochlus sure looks a lot like C. concolor.
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:Ageneiosus Looks a lot like A. marmoratus, but the paleness of this fish.....
Nice one. Thanks. I was struggling to work out what that one was.Marc van Arc wrote:Given the fact that it lacks an adipose, this should be Trachelyopterus coriaceus
