ID this cat fm Colombia

[amiidae]

Came in as Mastiglanis asopos. Fish abt 2-2.5in TL.



Thanks

[Jools]

Think it's probably

Heptapterid sp(3)

which I never did ID but I thought was mostly likely to be a species of

Imparfinis

.

Thanks, Jools.

Comparing the adipose fin of Heptapterid sp.1, 2 & 3 on PC, I notice they are slightly diff. Is it because of the age/size thing?

Here is another photo of my cat.

Cracking little fish Ben! What size are these? Are they behaving like Imparfinis, i.e. hiding in the sand?

[amiidae]

Thanks, Martin.

They are abt 2 to 2.5in TL. They stay under cover most of the time but don't go under the sand. Pretty out going whenever I drop food into the tank. Not fussy when it comes to feeding.

[Jools]

The photo in the cat-elog of sp(3) is an adult fish, but I do agree the adipose looks a bit higher in your fishes Ben. I am not sure,

Mastiglanis asopos

eyes look really different and this is a less likely feature to change with age. There is an outside chance they are young

Pimelodella

as they have large eyes, but I don't think so.

They should reach adulthood in a year or so, hope you can keep taking such great pictures of them.

Thanks, Jools.
Probably I wasnt clear in my first post. It was a wrong ID during import and definitely they are not M. asopos.

[amiidae]

Abt 3-3.5inch TL at the moment.

Any clue/guess on the ID ?

[Martin S]

They've really chnaged! Darker colouring and the shape of the snout has become more rounded. Very similar to a Pimelodella though the caudal appears to not be as deeply forked. Sorry that's no real help, but thanks for sharing the photos Ben. Really interesting to see how these are changing.

Thanks, Martin.

All 4 are still going strong. I doubt they will grow much larger. Probably top at 4-5in (I hope) which is really great for me.

Based on the initial photos and the first photo of the catelog, this overall look fits

Pimelodella sp`nhamunda`

Pimelodella sp`nhamunda`

I thought that too, but the fork on the tail is much deeper on the Pimelodella that Ben's fish...but yes, I can see the resemblance elsewhere. Maybe @Jools can chip in more thoughts?

[nvcichlids]

bad question, but is it possible that the picture in the catelog had a fin snip taken, making the tail a deeper fork than it really was? I know nothing about fin snip sample things.

[racoll]

Definitely looks very similar to that fish I collected in the Nhamunda. No fin clips were taken of the tail.

Fork depth looks similar to the first pictures posted, but maybe in the second photo the tail is bent slightly toward the camera, appearing to shorten it?

Check the dorsal for a faint dark wedge that could be present.

Yes. both are true for my fish.

Thanks for the tag, just following up as I can't really add more to what Rupert has said. These things are really hard to ID and the above noted species is from a collected area and fits the bill visually.
