Yeah, probably east african, tanzanian.
It may be a whacked out punticulatus, or closely allied species, or "morph", Hyperolids are really hard.... Cool-looking frog. It should have come in with similarily marked frogs? Why did it come in with a South american set of frogs? Is this to a petshop or something? Thanks, JVKPretty sure you are right.....looks like a reed. Maybe marmoratus or argus. I know that they are quite variable. I think stem is spot on, most of the reeds are exported from Tanzania. Beautiful frog though.
