ID this Pimelodella sp.

[amiidae]

My first pick-up of the year.

Fish is abt 8cm TL. Not too sure abt the origin but either Peru or Brazil. unlike the upper tail fin, FYI, the lower fin is rounded in shape.



Thanks.

Seen these described as Pimlodus Gracillas (wrong spelling) but cannot find any reference to those in the Family section of here

[Acanthicus]

Do you mean

Pimelodella gracilis

?

I´d agree with this.

[Martin S]

Pimelodella odynea

?
[EDIT]But looking again, the adipose on the suggestion is smaller than the fish pictured, so I'd go with the above![/EDIT]

IME, notoriously difficult to ID. Ben, please see this thread, possibly of help - http://www.planetcatfish.com/forum/view ... imelodella. Many look alikes in that family. See also the links in my posts (especially my second post) there and HH's (Silurus') linked site - if he says it is hard for him to figure out these guys, I have no chance. Other experts, like Jools giving up and The.Dark.One (Steve) and SidGuppy (Alex) being uncertain are additional pointers in the same direction

[amiidae]

Thanks for all the input.

The fish is more settled this morning and look pretty much like this - with that black marking on the dorsal.

That confuses matters even more!!
The large tail extension & dark markings on the Dorsal fin also suggest that this catfish could be Hemibagrus Olroides...see here http://www.planetcatfish.com/catelog/he ... roides.php,
also called Dragon fin or Rooster Catfish for their elongated tail extensions.
I'm the proud owner of one, however the line running along the lateral line is very faint & not nearly as prominent as in your 1st picture.
I'd say either P.Gracillas or H.Olroides

.... this catfish could be Hemibagrus Olroides...

Read this?

impossible, since Hemibagrus has 8 whiskers and Pimelodella only 6

South American catfish have no nasal whiskers, with exception of the Trichomycteridae.
most Old World catfishes like Bagrids do have those

the first picture clearly shows a catfish lacking nasal barbels; so even if the origin wasn't known, it could never be a Bagrid

my bad.. I was referring to the black markings on the dorsal. The shape and finnages just refer to post #1.

[Redtailrob]

That's what happens when i read posts too quickly!
didnt even see the origin as Peru!!
And paid no attention to the number of whiskers!!
So yeap that would certainly rule out Hemibagrus!! DOH

I can confirm that the fish in this picture by me also looked like the fish in the original post, when it was smaller though the adipose might be longer in these? Also the 'females' didn't get the top caudal lobe as extended. Here is the topic showing them when smaller:

We thought they might be Pimelodella metae.
