Anyone able to verify if this is indeed the Heterobranchus Longifilis ?
Note: There is a missing chunk of fin missing on the top fin.

Well, it is a Heterobranchus, but difficult to be sure beyond that.

What are the names of the possible Heterobranchus sp, could it be?

I only know of two that look like this. Bidorsalis and Longifilis.

Bidorsalis often has a black spot near gill as shown in this pic.

There is also but it has a limited known range.

Where was it imported from, mind you the two you already mentioned cover large distributions.

PM me your email, I can send you something...

Importer isn't telling me the location. Probably Nigeria

I don't think it is the longifilis as the head is fairly small. Here you can see a picture of a Heterobranchus longifilis (here it is crossed with a Clarias gariepinus

Its wild caught so its not cross. I did look at the longifilis x gariepinus link you posted. The adipose on the cross isn't at the same with what I have. The adipose on the cross is very short relative to the body length and dorsal fin. The H. Bidorsalis has the smallest adipose but interesting pic though, 100% this is not a aquacultured cat and the adipose on my cat 3x in length as the one in the link pic of the cross.

Here is a picture of the hybrid your suggesting. As you can see from the picture this longifilis x gariepinus hybrid has a much different (smaller) adipose.

Hi i believe this is the longifillis its exactly the same looking as mine and ive seen in person the bidorsal (sorry for spelling) ive never heard of the 3rd type mentioned mine was labelled as longifillis when imported and is also exactly the same looking as one ive seen at blue planet aquarium named as longifillis.

Always so difficult with these fishes.
Sold to me as C. Nieuhofi but fairly sure its Gariepinus
