Kind of hard to see n without the damage he has an underbite?
It's crazy how similar these fish are (if it is a true Brevis) .
I only question what you have because I have been informed from a well known Vendor that Brevis are from Sudan n he has tried to get them b4 with no luck.
Not saying they don't exist or are not floating around... I'm saying the extremely rare stuff he gets n can't pull these guys just lowers the % on getting true Brevis in the States.
Also, fishbase has lots of miss-ID species.
So... I hope you do own a Brevis or anyone else who claims to own one
