Amblyceps laticeps

[Silurus]

Snapped these pics today, from material sent by an Indian friend (also acquainted with Jools). Gravid female on top, male below. The cheek muscles of the male are a little more developed than in the female.



Apologies for the thumbnail, but the forum is not resizing the photo.

very interesting HH - i's the caudal typical - i'm trying to id a fish i got as a malnourished freebie that was an odd one in a group of (what i think are) mangois.

It sort of resembles protentum (wrong distribution?) but the caudal lobes look longer. I have seen it feed briefly so i'm hopeful it'll recover & then maybe get a photo.

Yup, that is the shape of the caudal fin of A. laticeps. This species is found together with A. mangois in some places.

[Richard B]

my fish is something else then as the caudal lodes are quite elongated

Cheers for the clarification HH

[Silurus]

Your fish might be Amblyceps tenuispinis (or what I identify as this species anyway).

Those are large eggs!

Are the differences in the adipose fin consistent for sexing them as well?

[Silurus]

I don't recall the shape of the adipose fin as being different in preserved specimens. Which is not to say a difference does not exist. It may, but I don't recall ever observing any (I was also not looking very hard anyway).
