Its ok. If you have a better ID, whom am I to complain? Unfortunately, I found a picture of Strongylopus fasciatus to deny your ID. Strongylopus fasciatus is a striped frog, hence the species name - fasciatus, which means striped. This frog is spotted and at first I thought it was one of the leopard frogs, until I notice the poster's country. Opening Alan Channing's "Amphibians of Central and Southern Africa" I found two frogs that looked very much like the frog pictured, but only one was found in the range of the poster. That frog is Ptychadena uzungwensis. Sorry, but Strongylopus fasciatus just doesn't look like the poster's frog at all.
