A LFS has GATF available, these fish are not that common here. Are there any telltale characteristics that I can look for to be sure that what he's selling and what I may be buying is indeed a Hydrocynus goliath. Please remember that there are no other species here to compare it with. I'm hoping that there's something obvious, because from the pics that I see the only distinguishable difference is the stripes. The specimin is supposedly around 7 or 8 inches.
