The head shape of this lungfish is much broader than the small annectens I have here:

Both of them are at about 4".

The shape gives it the appearance of a Protopterus amphibius. However, the mottling in the caudal area leads me to think this is a young Protopterus aethiopicus. (I have P. amphibius and it has never had any dark color or mottling).

(I have P. amphibius and it has never had any dark color or mottling). It could be one of the african sub-species of either Protopterus aethiopicus aethiopicus, Protopterus aethiopicus congicus or Protopterus aethiopicus mesmaekersi

Hmm... Can you elaborate more and list out the difference between the few sub-species?

I have never known about any sub-species.

Thank you.
