It's a kamalau and it looks like a male to me. Was it recently moved? Give it time to settle and it will be a nice one. Kamalau look really bad over black substrate also. Mixed colored gravel will really bring out this fishes colors.
This fish doesn't have any Thai Silk pearling at all, it would be either a Kamfa cross with a ZZ or a Thai KML. Kamfamalau is also a possibility on this fish no doubt. As far as being a male or a female, I can't say anything about it just yet.
thanks all for the info,
I will redo my tank soon, it was a used tank for my bichirs before, and I haven't done any setting for the FH just yet recently, I'll leave the homework till Sunday,
cheers
