Nice!!!
I have no doubt to call this
Key features I see are the spot pattern on the body and the caudal...greyish color and the grey barbels, in the second image it shows the highest point in the adipose is halfway as opposed to the posterior of the fin, only two of the current species are like this.
Tooth patch shape would say for sure, it is unique...we would have to figure out how to discern tooth pad shape, if it can be done with a photo of the mouth I am not sure at the moment.
That does not go with being from around Lake
Tanganyika but everything else points me to senegali.
You have the Revision if I remember correctly?
You can send these images as well...nicely done!!
