What is this Pimelodella?

[MCampos]

Hello friends

A friend bought this catfish but dont know the species.

Could you help us?

[sidguppy]

how big is it?

kinda hard to see, it looks small, but it might be 4 cm or maybe 8 cm.

these are quite hard to determinate and also: juveniles of

Rhamdia quelen

look a lot like certain Pimelodella's too.

the latter can be distinguished by the caudal fin; in Pimelodella the lobes are pointed, in Rhamdia quelen these are rounded.

I've had a few of these. Never gotten a firm ID on them. You can find some in these photos, if interested http://www.planetcatfish.com/forum/view ... t=+120+gal

This may be relevant too http://www.planetcatfish.com/forum/view ... =7&t=33289

Sorry, not much help.

The lobes are rounded. Is it a Rhandia? Whats species?

My first thought was

Rhamdella leptosoma

but I think the base length of the adipose fin is too short. I am not sure even if this is a

Pimelodella

. Sorry I am not much help.

well, the headshots are good; it's definitely not a Rhamdia, that's for sure

in Rhamdia the lower whiskers are long as well, only the innermost pair on the lower jaw is short

these fish have 2 long whiskers and 4 short ones.
not Rhamdia.

2 long whiskers and 4 short ones + rounded lobes. One suggestion? rs

Do you have another image showing the full caudal fin, it is the shape of the whole fin that is needed.

Hello Ian

I have this:

[The.Dark.One]

Based on the supraoccipital process meeting the nuchal plate this is a Pimelodella not a Rhamdia IMO.

see this thread and the links therein http://www.planetcatfish.com/forum/view ... =7&t=33289

perhaps, especially Silurus' ACSI web page

[MCampos]

and Pimelodella avanhandavae?
