ATF is probably too small to identify at this point, I don't see any coloration anywhere. His snout doesn't say goliath to me, but I'm not an expert at this. My TATF has a dark blue adipose fin, and that pic the fish looks to have a clear fin.
Hard to say... If I had to guess I'd say FATF but I wouldn't put any money on it until it grew out another inch or so.
