There are a lot of fisheye options, but it all depends on what you want to spend. That camera has a 49mm filter, so you'll need to match that thread size. You best bet is to find a lens that is closes to 49mm (in filter size) and if you need to get step up, or step down rings if you need to. You will only need the step up or step down rings if you get a lens that is too big or two small in terms of filter size. You can use the step up and step down rings to adapt your fisheye lens to the camera lens threads itself.
Hope that was not confusing and helps a bit. Below is a link of lenses you should be looking at. Specifically the ones closes to the 49mm filter thread. You can narrow the results on the side bar, in terms of thread size, brand, price, type of lens. Thanks!
