No thats not a Black Belt but it is definitely a Vieja. My initial thoughts were V.Zonatum but had a quick flick through some pictures and Vieja Guttulatum could be a match. Cant tell from the pic but not ruling out Bifasciata female as well.
Could do with clearer pics of the face markings if possible. Also do all the unpaired fins have a red edge to them?
