Fahaka's vary in pattern alot! Although yours looks like the pictures of tetradon mbu puffers.... whether these are different i dont know, its hard to keep up with scientific names of a species you dont really know about, let alone one you do!
If you type in "tetradon fahaka" into Google image search it does come up with a couple which look alot like yours so i guess it must be a nice fahaka!
