Philippe, I agree that it is the same Tilapia species which is figured on your website (having checked back my sources, I found that I was completely wrong with Sarotherodon g. boulengeri), but I am not so sure if this is really T. louka, at least it is apparently not the species figured in Lamboj's book under that name. But there is certainly not enough known on the variability of life colours of this and related species.
