I picked it up on the weekend. I had tried to get some pics of the underjaw through a clear bottom tank but the light was crap, visually I wasn't really able to see it, I fished it out aswell, still difficult. I suspect 4-5 pores. I am letting it settle and I will try and get some shots, fortunately it seems to sit upright with its head raised in the air. I would say the previous underjaw shot is a good representation of the alignment. I would say there is a definite U rather than V.
The fish was exported from Venezuela originally. Does anybody know, is it typical for a northern i.e Columbian, Venezuelan exporter to export fish from the southern regions.
